Well I finally got it put together and running today. I moved the Handlebars closer to me than factory settings and I also went ahead and striped the racks. Its about 30 degrees here in North Carolina so I didn't ride maybe an hour or so. :'( The power is real strong, it just has a slight low end bog about it. It handles fairly well but the turning radius is sad. Do they all do this or what? I really like the seat and the lights as well. I have a pipe on the way and I am going to pop out 2 rollers of the clutch and the low end bog should go away. But so far I am very happy and with a couple of mods I will be on my way to a 2008 lites class championship. :o ;D
-
Allright.....been waiting on your review.
Yes, you reported everything just like I thought....
Power is strong, except there is this low end bog. Removing the two roller weights does wonders here as well as just getting through the break in period and looseing up the motor some. I run 26" XTR's and I can spin them now....before I could bog it down with my 25" stockers.
The pipe will wake it up as well....what pipe is it?
The handling is ok, but the a-arm improvements that 500Racer2 and Dan (he rode the Mongoose last year) are working on will eventually make it to stock units and that will drastically improve the front end. Make sure your toe in is set right...that adjustment helped me a lot!
Please keep us informed on what you think and what mods and all you do.....it helps us regular guys out alot :)
-
First of all, why does the newest member of the team have quads and last years riders don't?? Second of all, taking the rollers out will not remove the low end bog completely, it is the fact that the machine weighs 700 lbs. and there is nothing to strip when it is race ready, and third of all, 2008 class championship over my hairy @$$!
Waa, Waa, Waa, its 30 dgrees here in NC, suck it up, its 8 degrees in Ohio.
Bring it, Newbie !!!!!!!!!!!!!!!!!!
-
Yea as soon as the AC pipe gets here I am taking off the airbox lid and throwing in a K&N along with the clutch mod. That should wake it up nicely. I am just wanting to get that GT thunder front end on there and that should take care of my little problem. I have a set of GBC dirt tamers going on it shortly. Stockers don't cut it.
-
I am surprised to see you guys running dirt tamers....aren't those like the Maxxis Bighorns? I figured those would be too heavy for you racing and you guys would go with something lighter. Don't get me wrong....I might get me a set for Summer riding (when it is bone dry and rocky....the XTR is not the best there I found out this year).
500Racer2.....you d man.....I am glad I am not out there racing against you....you'd have me all spooked :D
You guys are gonna be a hell of a team....four Kymco racers all on the line side by side going for the hole shot every race...look out.
-
I live fairly close to the Kymco distribution plant so I went and got it. I like dirt tamers for all around use. Check your messages robey. I am gonna bring it and you aint gonna stop me. :o
-
ROBEY QUIT WHINING YOU GOT MORE QUADS BESIDES YOU WONT RIDE IT WHEN YOU GET IT. YOUR TO BUSY EATING TWINKIES AND GETTING FAT. :-*
GIVE THE KID SOME SLACK I MEAN HE REALLY THINKS HE IS GOING TO BEAT US!! HE DONT REALLY THINK WE WOULD TELL HIM ALL OUR SECRETS!! ::)
-
This is BS, I want to speak to the Assistant MAnager!!!!!!!!!!!!!!
-
HAHAHHAAHAHHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHAHAH :o ASSISTITANT MANAGER!!! UH OH!
-
Don't make me call HER!!!!!!!!
Hey Newbie,
Try puttin some Maxxis Mudzillas on that quad, it will help you wth your Holeshot!!!!!
-
Mudzillas huh? You need some 32 inch silverback's. They dig real deep. :D
-
You need to get the EPI clutch kit and put the white spring in the secondary, you will be amazed at the speed you will gain.
-
I beleive you ken. Well guys I made a mid pipe for the LTE muffler I had laying here and man that opened her up. I also put in a polaris 800 K&N air filter with 3 holes in the lid and an outerwear on the filter. The stock filter is a piece of crap. I also took out 2 rollers in the clutch and that helped it out a bunch too. Now I need a white secondary and maybe the lowend bog with go away. I wish I had some video of my exhaust because its so loud. ;D
Mxu_red are you close to durhamtown, because I need to make a trip down there one weekend.
-
So 4ooracer...
With the new pipe and K&N and the holes in the airbox....how responsive is the throttle at low end? When you rev' it up , is it real responsive or does it stumble at first?
Just curious because I can not run with a open air box lid...it stumbles real bad from idle to a throttle stab. WIth the airlid on, it is good.
Anyway...I am about 1.5 ours from Durhamtown. Also about 1.5 hours to BroadRiverATV park (Broadriveratv.com) , which is closer to you). I am thinking about making a trip myself real soon...When you wanna go?
-
I left the lid because I don't want to risk water jumping into it. Its smooth right off the bottom all the way through. I am impressed with the power. I need to know how to stall this thing??? Let me do some checking on where I can go and when we can do it.
How tight are the trails at broad river? Are they tight?
-
......
How tight are the trails at broad river? Are they tight?
Broad River ATV has a big variety. It has a 12 mile main loop and 100+ miles of trails off the loop. Most of the trails are not real tight, they are pretty wide and the turns are mild. They are mostly rough, mud hole type trails...good Utility ATV trails.
They have some real tight trails that were made when they cut some courses in for the woods racing series down here but thoses trails are not always open.
The good thing at Broad River is that all the trails are one-way.
Carolina Adventure World is a good place to ride with some tight trails, off camber, you name it.....you ever been there?
-
Nope, the only place I ride is Buffalo Valley and i81 motorsports park in Tennessee. We need to get together and go ride. The tighter the trails the better it is for me to practice on.
-
400 racer can you come over friday and stay sat. ? Dan and i are going riding so be prepared for old school riding..
Robey well break him in right !!!!
-
I'll smoke you guys. :o We gotta go the Mid-East banquet saturday at 3:00.
-
you wil be to tired !!!!!! us old guys will be fresh as daisies..
-
You on a 300, your arse is had with me on the 500. You'll be deaf when I get through with you. ;D
-
400 racer....you'd love riding the trails I have on my property. They are tight and full of roots and small stumps.
I try to race them (yeah.....sometimes I pretend I am a racer.lol) hard and do ride them pretty hard but with these stock handlebars ('07 bars are swept back too much) and these 26" XTR's.....the 500 is a handfull. I have to man handle it WAY too much to stay off a tree or make the next turn. I guess this is actually a good thing if I were training for a race. My son on his MXU150 can rip them up. I can do a good job on the 300 too.
A few years back I would invite you all to come ride here, but it has growed up around me so much lately (subdivisions everywhere) that I can't make as much racket as I use to.....somebody always complains eventually...
Sound like the 'Manager' has some good riding places....you going?
-
I beleive I will. He needs to learn how to keep up before we get on track and he go's :P :'(
-
Remember, Rubbin' is Racin'
Show him how its done, Kev
-
LOL :o
-
I need your address Kevin. ;)
-
He doesn't have an address, he lives in a trailer and moves it from Wal-Mart to Wal-Mart.
-
Awesome!!! Guess what Robey! I ordered some PINK powermadd handguards just for you!!! I heard you would like them so... ;D
-
Dang Kevin, I forgot to say thanks to LOONEY TUNED EXHAUST. :D
-
hahahahahahahahahahahahahahahahahahahahah ??? silence...... i kill you.... lol
I LOVE JEFF DUNHAM HE IS FUNNY
-
Yea he is funny. I found a z400 steering stabilizer, will it work? ??? OH yea and why don't you have my seat covered yellow where the one you gave me was blue and then I'll swap with you whenever. ;D
-
I know Ken was running a stabilzer on his 500 last year. He said it helped a lot...I have been meaning to ask him what brand/model it was.
Walter for President! :)
-
PRESIDENT SAID NO YELLOW AS THAT IS CAN-AM COLORS !!!!!!!!!!!
kaboooom
-
What? Are you joking? A little yellow on a big blue 4 wheeler? Come on Kevin...help me out a little.
-
If you want Yellow, go to the DARK SIDE!!!!!!!!!!!!!!
-
Already been there and I found the light! :o
-
MANAGER AND ASS. MANAGER DREW COLORS.
KEN GOT PINK
DAN GOT ORANGE
JORDAN GOT RED
KEVIN GOT WHITE
NO YELLOW........ ITS AN EVIL COLOR...... ANY ::) QUESTIONS ?
-
Where's my red powermadd's, red and black omf's and red spider grips? ??? My shocks will be here next week. ;)
-
SHHHHHHH NO ONE LISTED omf !!!
-
And my red, black, and silver seat cover. :o Oh my ksa tall bend bars and nice red rox risers. ;D Kevin you're gonna be busy...
-
i THINK YOU RELIZE IM ALWAYS BUSY...LOL ;D
-
LOL. You are gonna be ??? before the race seaon even starts.
-
sounds like the Newbie has got you all tied up, no time for us other racers, with all the tour dates and autograph signings in Atlanta.
-
Kevin knows im gonna beat you old guys so he's helping me out as much as he can. :D
-
And my red, black, and silver seat cover. :o Oh my ksa tall bend bars and nice red rox risers. ;D Kevin you're gonna be busy...
400racer...I'll take your stock bars (if they are the newer bend -08's) :). I have been waiting on the new ones to come in but months have past and they still have not arrived. I am trying to avoid going the riser/aftermarket bar route....want to keep it closer to stock if possible.
Sounds like that 500 of yours is going to be one pimped out racer 8)
-
Once I get my Ksa bars and stuff I'll bring the stock ones to you at a race. ;)
-
Thanks 400Racer :)....if I haven't got them from Kymco yet I'll talke you up on that.
I should be at the race in Washington and then maybe a few more after that...
-
Pimped out racing quads don't look as good when they are sticking out of tree limbs.
-
500Racer2....how long do you give him before he has a stick through the radiator ?;) :D
Hey.....why are you not down at the big autograph signing coming up? As I recall you were the one on the top of the podium last year , right? They not giving the love.lol
-
I know ken, your's looked awful after snowshoe. :D You were :'( wasn't you?
-
I know , not getting any love up here. Raced my heart out last year and never gave up. Helped Kevin build that Kymco Team but must have got lost in the shuffle. Funny how the guys that help you get to the top are always forgotten. Got to go to garage now and freeze (18 degrees), while I transfer my old quads to new frames. That's OK Newbie, you don't have to help, just enjoy riding your brand new 500 around and also that brand new 400 that I will never get a chance on. Guess thats the way it goes, the Team sees other talent and forgets all about the ones who help put them on the map.
Ken "No Love" Robey will be on my old chest protector this year.
-
I would help but you're a long ways from me.
-
Heres a side shot of her.
-
Front shot.
-
Rear shot
-
Angle shot
-
Looks good......looks like a MXU500 racer!
I got to get me one of those seat covers like use guys use...(a red one of course)
Hey 500Racer2.....don't forget poor old Dan too....the unspoken new 4x4 lites racer.....he has always been with out the love too ;) ;D
-
Boy, would like to know where you got those nice nerf bars, going to have to speak to the YOUR manager first thing tomorrow.
-
I made them fit. I thought you had some too??? ??? I did the diamond plate myself.
-
That is a great looking quad. :o Nice work.
Who makes the exhaust? Is it a slip on or full system?
-
Ac racing slip on. Thanks for the props.
-
That quad is ugly, here are some pics of a real quad, with real racers, and a really pretty WOMEN!!
Click on pictures to intensify your viewing pleasure.
-
Who said I was done??? ;D You got a quad together yet Robey??? Are your nerfs mounted to the plastic? One more thing, do you have a pic of that stabilizer up close?
-
Awesome!!!!
-
One more, Newbie
And, Yes, that is Kimberly Pressler, Miss USA 1999, with her butt planted firmly on my seat!!!!!
-
/\
I like.
-
No stabilizer pics, could get you one tomorrow when I get the chance.
-
I would appreciate it. Do you just have a pipe and filter? When its cold mine backfires quite a bit on decel but runs great WOT. Do I need to rejet? I got the white spring in and it did help out a lot on acceleration.
-
Mine backfires on decelleration as well..I have not rejetted although 500Racer2 recommended going to a 148 main.
500racer2...love the pictures.....did you say there was a quad in the picture? All I saw was the flat bellies :P
Hey guys...how would the white spring be for a trail rider like myself? Since I am running a larger/ heavier tire I would think it would be ideal. Would you recommend it (going to white spring)?
-
The white spring is a good, cheap mod for you. I have a question to you mxu, why do you use 26inch xtrs? Are you in that much mud? Robey tell more about rejetting... ???
-

Excellent question about the tires .... When I first got my 500 it it was rainy season and all the places I rode were mud parks. I thought then that the 26" XTR's were ideal. But since then we have had a drought and most of the riding I do is not on mud anymore. I really would like to switch to a tire like the dirt tamers you are using ( I was looking at the bighorns already) . I just don't have the cash to go buying different tires at the moment.
Get some feedback from 500racer2 and the Manager on the jetting. They both actually have different opinions/experiences with jetting on the 500. One uses less and one recommends more.....I'd like to see what you come up with.
-
Both of my quads have the 148 main in them and they run flawless. Remember Newbie, more air out the tail means more air and more fuel in. That is your Physics 101 class for today kids.
-
One more, Newbie
And, Yes, that is Kimberly Pressler, Miss USA 1999, with her butt planted firmly on my seat!!!!!
Nice looking quad! ooo, 1999 and she is still looking hot!
-
Mxu you could buy a set of GBC tires and sell your XTR's and still make money on them.
-
Robey, where do I get a 148 main at?
-
I tried that white spring at New York last year and for racing, it is not the choice. For the woods, I think it would work great for you. It grips the belt really well, gives you more low end because it takes longer for the secondary to open up.
-
I believe its a Keihn Jet. Should be able to get them at any dealer.
-
What spring are you using? I put in the white and I was impressed. Did you you a pro design or pro armor kill switch?
-
I believe its a Keihn Jet. Should be able to get them at any dealer.
Boy Robey he is a rookie LOL, I found my jet in the clothing section at wal-mart lol J/K good luck this year.
-
I saw one fly by at the Pittsburgh Airport the other day too. I use a Pro Armor on all my quads. But, remember, just because you are using the equipment that I tell you to use, that in no way will make you even close to being as fast as I am. Yes, that just happened!! Shake & Bake!!!!!!!!!!!
-
Pro armor is what I thought you said but i wasn't sure. The only thing that will be shaken is you after your quad gets through bakin'. LOL :D
-
400racer....have you got a chance to change the jetting yet?
I got a guy ordering a few jets (diiferent sizes) and we are going to experiment on mine .... maybe next week. I will try the 148 first and go from there.
I want to get the white seondary spring in as well. Now I put the stiffer spring in my MXU300 and I like it on tight fast trails but don't like how it is on the open straight runs. It seems like it needs to shift to a higher gear but never does.
That is my only fear with going with the white spring on the 500....is is going to do the same...
-
I am getting the 148 put in tomorrow. As for the spring, I like it a lot. No matter what, the 500 will top out at 61 and the white spring will help you acceleration a bunch.
-
;D mine will go past 61!!! get ready rookie!! they call vets and past CHAMPIONS for a reason....
-
And you talk about Can-am, blah blah blah. I think I won the 2007 MID EAST HARE SCRAMBLE SERIES and I place higher than you in both GNCC's I raced. :o You just worry about the real riders (ME) and get my stuff ready. lol :D
-
you guys crack me up. :D
Any races near Chicago this year?
-
Last race of the year, Crawfordsville, IN. I am going to let these two battle it out on the track and I am going to just cruise on by. I hope this Rookie can ride, he sure does do alot of talkin', if he doesn't perform well I will be talkin' to the bossman about him walkin'. Goodnight, hittin' the gym at 3 am.
-
Hittin' the Gym my arse. :D Boss tells me I get rookie strikes like Nascar guys and my new nickname is Rookie. ???
-
You guys are having too much fun :)
(I can see 500racer2 carrying those logs on his shoulders through snow right now... :D)
Rookie...sounds like you'll have more Kymco blue marks on you than stripes from all the other competition....
I seen 500racer and 500racer2 share paint on the start at Yadkinsville....now 4 of you.....how many piles ups we gonna see at the holeshot line..lol
-
Did Kevin also tell you that YOU as a ROOKIE get to wash of all quads after each race. Hope you have a pressure washer and a 100 gallon water tank for the back of your truck. Sorry , but this is what ROOKIES do to earn their stripes>
What is the deal with these shocks, can't get ahold of Kevin for some reason today, I just got home from a hockey game and I have a set of new ___ shocks on my front porch. The packing list has Jordan crossed out, Kevin crossed out, and my name wrote in. Is this supposed to be a surprise. If so I appreciate it. Wasn't going to be able to get these for at least another month. Money is tight. Who do I owe the money too. I hope you have me on a payment plan. They are really great looking shocks. Going to bolt them on later today and see how they work. That is racer respect, giving these to me before you guys get them. Thanks you two, you really made my day!!!!
-
I love helping people. ;)
-
Hey Rookie, "How did the race go today? Want a full race report asap.
-
Ken thanks for the nice screen background pict. it looks cool lol
-
You got 2 pms racer...
-
nice pic! Is that 400racer?
-
You got 2 pms racer...
Hey.....no fair....you share race results with all of us ;)
No Turnbuckle....that was a pict of 500racer2 himself on the MXU500 last year...right racer2?
-
Yeah, thats me. 400 racer would be the one upside down in that shot. your welcome bombman.
-
LOL boy's you and Kev. are sure giving it to the rookie LOL. ;D
-
Thanks Pappy off of Atvriders....
-
400racer....looks good.
I see you got the new wheels and shocks on.
Did you ever get the jetting done?
That was a race you were in?....How did it go? How is the 500 running?
-
The front shocks, wheels and tires are managers just for temporary testing. I left the jetting alone also. The race didn't turn out well, fouled a plug and didn't even make a lap. It looked good though.
-
That sucks man. Lucky for them. Next race they will fee the wrath of Kymco!
Cool pic!
-

Wonder what caused you to foul the plug?
-
Excessive choking.
-
Excessive choking.
Yeah...that would do it. I think the 500's run real rich already in the idle range. I got a guy tweeking on my 500 as we speak. We have the 148 main on order but I think it is the primary is where mine needs a slight adjustment and where I will see more improvement.
Even with K&N filter and AC Racing pipe....you can see exhaust rich fuel smoke when I first gun the throttle. I think the primary is rich. Going to the 148 main will help the top end now I would think, but I think maybe tweeking the primary will help my throttle crispness and response.
What do others think?
-
I think the 148 is gonna kill it. It has a 128 in it right now and it is rich so you put in the 148 and bam. I would drop it a couple of sizes. There is no primary Jet. There is the main and pilot and a few others like the choke jet.
-
Yeah...I was meaning "pilot" when I was saying primary (thinking CVT I guess).
I meant that the pilot is real rich but the Main is the one that everyone has talked about changing after piping and K&N filter.
I am thinking the pilot jetting or needle valve is what needs to change to lean it up some on the low end....the 148 main would only show up at wide open throttle. I don't know if mine is lean or rich at wide open thottle.................ok...my eyes have crossed ;D
-
Interesting, keep me informed.
-
do you guys have a part # for the K & N air filter?
when I go to their website I don't see Kymco
-
Inside your airbox there is like stop plate for the stock filter. I broke it out and installed a polaris 800 K&N filter. Works great for me.
-
thanks 400 racer
