Hey all! Get ready for a long single paragraph rambling post! OK~Here it is. The Malossi 47mm jug ran up 67mph new. 64 after 2 years. 60 from the third on... The whole set up was a 28mm Delorto (48 pilot/150ish main), K&N style air filter, Malossi reed block w/ Boysen .30 carbon reeds, Technigas r2 pipe, Suatai re-programed cdi, Malossi Delta clutch (2000 rpm fly springs, and Yellow Contra spring), Malossi Var. w/ 5.5 malossi rollers. All of these bits were tweaked a bit to get more out of them.
The new setup is Oko 24mm pwk carb (47 pilot/115 main) K&N style filter, CT intake, and fiber glass reeds, Ruima 50mm jug, Ruima "capped" 44mm stroker crank, Jiangwayne stainless pipe, Same Suatai cdi, Malossi delta (2000 fly/Red Contra) Malossi 6gr rollers.
First the crank. The bearings are a BIT*H!!! Use the hot/cold method, and use the case bolts to get it together. Check the clearence of the Con. Rod big end after the crank is in. It may get too tight, and you will need to re set this. (I used a fiberglass wedge to adjust this)You have all seen Bat's Picts. of the case porting soooo. I added a few things to the cases. Remove the tabs left after the boost port is cut, Remove the large support opposite the boost port. Drill the crank oilers to 5/16", and chamfer top and bottom of these holes. Remove all the material in the intake passage. Match the cases to the jug. Match the cylinder skirts to the cases. Chamfer all the port edges inside the jug. Polish the exhaust port w/o changing the shape of the port roof. Mirror polish the top 1/2 of the cases. (intake thru transfers). This step will allow the oil to slide down the cases to the crank where it is needed. Also Scotch brite the bottom of the cases to make the oil "stick".
The Ruima jugwill plug, and play alone, but needs attention w/ the stroker crank. (1) gasket top, and bottom results in 13.7:1 compression. Can you say hand grenade? You need to bring the jug up 2.4mm., and for breakin use an extra head gasket to keep the compression low (10.2:1). There are no locater pins in this jug/head so you will want to add a pair to the stud holes. The jug timing is very good for the exhaust duration, and the Intake is just a little low. (188* exh/127*int) but is is good for everyday.
Now the piston... The piston SUCKS!!! Cast alum, and not very well finished, Drill (2) 2mm oilers for the wrist pin (chamfered inside, and out) Dimple the exh side of the dome 1.5mm from the edge I used a 1mm wire bit to drill 8 dimples. These will attract heat away from the edge, and prevent melt over on the rings. The skirt also needs to be beveled to a negative 22* to push oil onto the cyl. wall vs the stock removal. Chamfer all the piston edges when done.
This kit MUST be run on Pre-mix. I tried the pump. and adding 2t to the tank but it just is not efficient enough, and you will get 4 corner scoring on the piston.
Run 7-8gr rollers for break in
Run 1 clip rich on the needle for break in
Run 1 turn rich on the idle mix screw for break in
Use a BR9HSA NOT the BR8HSA
Now for some fun stuff... Use a Ruckus Variator. They start at 94mm, and go to 104mm over range. I have a Prodigy Ruk. at 97mm, and love it. You need to remove the electric start motor to use this, but it is worth it. The Var. will not fit the cases unless you remove material from the starter housing, and you will need a NEW zx/50 drive boss. I say new cause the Ruk uses a 15mm crank, and its drive boss won't work. Your old zx boss will but it will be worn, and for 15 bucks why blow a case up? You will need a longer belt now... 735x18.5x30 is the new size. I had to shim my boss .3mm to get a good bite at full stop. I forgot to say use your orig ramp plate. you want the belt to be running ON the boss at full stop.
More fun... I "glassed" all of the rear body pannels into one piece. I remove two bolts from the seat pan, and two nuts from the tail light, and the whole saction comes off for easy access.
Now the fan has sort of a screen in front of it. Remove it!
Same w/ the cvt cover. There is a circle over the clutch that says Kymco cut this out to cool the clutch.
Here is the bottom line... The scoot now does 143mph in the power band, and 127 cruise. It will run on Vodka/gin/ whiskey, but I'm not sure about beer (Slinger) Maybe a fatter jet?.?
Nawwwwww Really is MUCH quicker at take off, and hits my old top speed at 3/4 throttle. I haven't opened it up yet as it takes too long to get pistons. My guess is approx. 73-74mph. I have a few picts. to post, and I'm sure I missed a few fine points so I will stick around to answer any ?'s.
I love my Bro's here, and think this set-up will be one for the books~ CHEAP (yes)/FAST (hell yeah)/DURABLE (?) My camera is at the shop but I will get some more Picts. Mass Iridium to all~
-
Totally awesome! MOre pics with it together please! Go Zombie! I did like your old color scheme, I guess that's gone now.
-
Just Awesome!!! Glad to hear you're still around...it's been awhile!
Mass Iridium!!!!!!! ;D

Yoooooo! How's my big Bro doing? Still got the ZX? This build has me stoked. So far it has more power than I expected, and runs like a DREAM. I kept up w/ Bats. thru this, and he can tell you it had some pitfalls. 1/2hr. pistons, and such. I truly searched the world for the parts I have in it, and am still looking for a flat top Forged piston to finish it, but for now (breakin) the Ruima piston will do. I have a box of variators/pistons/different types of rings/belts/rollers/ cylinder head experiments/carbs... I just took my time, and researched EVERYTHING! This build can not be beat! The best bit is the smoothness compared to the Malossi. Power is constant all the way, and it really does Huuummmmmmmmm! I had to share this as I believe it is as good as it can get. It actually sounds more like a 4t Formula car than a 2t dirt bike. Oh yeah... NEVER use a 4t qmb engine on a Goped. If you do just break your arm FIRST! (saves alot of walking)

..mass iridium!!!
..look at this...th gangs all here!...
..wheres batty??

He's been MIA for a few days. No posts/emails... I think he is holed up in a brothel somewhere... I just got the pun!
-
Oh yeah. The old paint job is still there..W/ all the others.
-
Here are a few more picts. Still not good but that is why I don't post many. You can see the extension kit I built in one of the picts. It added 3.25" in length, and lowered it by 2.25" This can be done w/ (1) piece of pipe, and (2) 1/4" steel plates. Nothing on the scoot wiring/controls needs to be changed to add this. I did add a spacer to the shock to gain back 1" I can't say why the Factory scoot is so short but the handling is 100% better stretched There is one Pict. of the open fan. I added a 3" collar to the shroud to get the air intake out to the open air. Can't see it in the shi^^y pict. tho. The engine is sprayed w/ Nason 2 part urethane enamal.(fuel proof). The whole scoot is done w/ Awl Grip 2 part urethane enamel. NEVER needs waxing/fuel proof. I also mod'ed the seat by removing 1" of foam from the front 1/2. Lower look, and better feel. The last bits to do are install Pirelli Diablo 130x70x12 front, and rear, and spray the rims. I am expecting my 5 year old grandson will be having this scoot in a few years so it will be a Zombie forever. Next 50cc project? Aprilia sr 50. (Found one today). Maybe that one will be a 103cc in a month or so... Ps. I had my Malossi jug bored to accept a JN 47.5 mm yamaha yz80 piston. This will ONLY work w/ a 46mm crank so if anyone wants to get into a stroker project on an af18 or newer engine let me know, and I can hook you up!

Forgot the F'n picts.

I hate posting picts.

Great thread z. I thought i had emailed you. Oops, maybe i didnt.
I havent any good news to post about lately along with the crash of my computer.(hopefully it's fixed)
I hope to have mine repaired very soon and ride my lil demon...lol

..nice work z-man!

A little updating...No major issues till 3-4 days ago. I wound up at 9gr Dr. Pulley rollers. Rpms were spot on at 55. Right on the pipes 8500 rpms.
I have had to replace the small plastic sliders in the var 4 times since the build. (rattles at idle). Soo the other day I thought my torque drive locked up because I had no low gears. Opened it up to find the rollers were in dozens of pieces (metal, and all) The Ruk var is SHOT. So I dug out the Malossi I have used for 4 years, and a new Malossi belt. Got about 20 miles, and the sliders broke again digging the ramp into the var, and shredding the belt. Back to OEM var, and Bando OEM belt. 50 miles this time, and I started hearing that sharp LEAN pop thru the pipe. Throttle down to get home, and never made it. The Jw pipe had cracked at the mount, enough to lean, and melt the piston.
I have called them tonight, and will let you'all know what happens.
To top this off I took the old Malossi jug, and the spacer to install on the cases, and it wont fit due to the porting (boost port) There is a 1mm air space behind the cyl at the boost port. Soooo back on the spare engine... Spare in the zx... Old pipe, and 19mm delorto. Even stroked the Malossi has NOTHING on the Ruima. I still get 60mph on the set up, but it takes forever to get there compared to the Ruima.
The bottom line is the Ruima makes so much torque it SHREDS variators/sliders in a couple weeks. I have had three variators, and 5 belts blow in three months. Anything bigger (125cc drive) is too heavy, and lowers power.
After I build it AGAIN IT IS FOR SALE. I can't be wasting time replacing all the drive train every few weeks. This scoot is really more race than street. If I tune it down I am not happy with it. I tune it up, and parts don't last. I have considered jack shafting, and running external pulley sets but again too much trouble for everyday. The scoot will be rebuilt, waxed, painted, and sealed in a glass box till sold.
Aprilla here I come.
In the mean time I am running the Verucci 4t Ruk style. It gets 50mph on a 50mm bbk, and that is just fine for now

Is this zx been raised?I want to raise mine too does it look better like this i cant tell from the pictures.Do you have a picture before it was raised?

Not raised but lowered, and extended. The scoot looks bigger due to the extension. It is 3.25" longer at the wheel base, and 1.25 shorter at the seat.
The zx is weird. It has an extreme rake on the front end (chopper style) that benefits from raising the rear but then the wheel base is so short it wants to under steer when rolling the throt. out of corners. Look close at the frame picts. and you can see how I extended it. (compare to yours...)
...dammit man!!
That's exactly why I'm selling, and how I feel about it.

I never thought I would be upset it is too tuned. Like having too much Hippie grass... Well no. Like too much poontang... well no. Like having too much too much... Yeah. That's it! Too much of a good thing.

If they still have the same lead in C & C, she was smoking hot.........

I'm still around guys....
Don't freak out!
I think you all have my # too so....?
Nothing new on my end...just trying to ride!
I'm done F***ing with her till I have too!!!!
Everyone's bad luck better not trickle down!!!!!!!!!!! >:(

I pray it doesn't... 2 is more than enough... ;)
I don't blame you there, leave her be......... for now.. ;) :D
-
I thought it was GOOD luck. You know when a scoot hits warp 11, and all. Mission accomplished...NEXT!
Good to see/hear/read you Shaka.
Slinger...Poontang/Twiffle/Snatch/Cum Dumpster... Get it! I thought not
-
...i was just surprised you could get too much.....
-
Slinger...Poontang/Twiffle/Snatch/Cum Dumpster... Get it! I thought not
I like the phrase "Nut Rag".... :D
-
Hahahahaha!
Yeah, possibly...I'm still at warp 8, no need to exceed 10! ;D
-
I don't blame you there, leave her be......... for now..
Beat that bit(h till you can't stand the sight of her. That's the answer to tuning. Like a NOS Yugo! Beat it till it is out of blood.
Step two is: Find a Voodoo Priest, (like the minister at my last marriage) and bring it back to life as a Zombie, and KILL IT AGAIN. That is the tuning TRAP! When does it ever end... ZOMBIES ARE FOREVER!
-
..,see.....
-
Mine won't move.... Wouldn't be any fun beating an idling handicap.... :D
-
Hahahahaha!
Yeah, possibly...I'm still at warp 8, no need to exceed 10! ;D
I guess that's why you are you. Ever rolled a Hippie smoke in a corn husk? One lasts for hours... WARP 11! Eight = tiny pipe!
-
Lol!!!
I know...that is the trap! At least till you get it figured out enough to hit warp 11!!!
I'm actually been rebuilding my car, so the Z has been neglected.
Really need to tweak the carb on her too.
-

Like shooting monkeys in a barrel huh? I LOVE monkeys but shooting a barrel full is more fun than a barrel of mon... Oh yeah I see your point!

What kind of car? I'm sure it needs a dual quad set up, and some gears, and a triple shift 6 speed trany. Stick around for the build Bro!
-
Bet you mine will idle longer than yours?!!!
Are we allowed to keep topping off the fuel tank? ::)
-
Just put a new head amongst a lot of other sh*t on my Acura Integra.
-
50mm Pistons? I have a box full!
-
IDK if mine would idle long enough to even need topping off... ;D
I like those Acura.. I loved mine.. ::)

I forgot to post the latest. I spent all day setting the Malossi on the zx cases. Made a new shim, and found I still had a vacuum leak so I tore it apart, and set it on the spare cases. Took ALL the good stuff off the zx, put it on the spare cases, put the spare in the ZX, and was ready to start it around 7:00 tonight to look at the bench to see the wrist pinn cir. clip. NOW I have to tear apart the top end to install the clip.
All the new parts are on the way for the Ported cases. New JCC piston/Jw pipe/Rubber coupler for the intake/Jasil Var/Malossi belt/Dr. Pulley rollers. I am debating leaving the Malossi in the scoot, and having the Ruima as the spare. (New In Box) till it sells.
I should have taken up glider flying...
-
I should have taken up glider flying...
....ummm...no...itsa long fall from 1000ft...
:-\
-
We should all set up a meet. Maybe Skadamo will spring for a week in Belize for us! I promise not to swear. Oh f*** it... Maybe a day or two at the super 8 inns. (ha ha I made a funny)
NO NOT in the pants!
-

One of those really LONG screams no doubt... Might be the best twenty five minutes of your life tho!
-
That would be the shiz nit..... :D
Speaking of glider, did anybody see the like 48ft PAPER airplane in flight?
-
ohhhh Sh*T Z! That really sucks!
I would love to get up with all you guys for a ride though!!!!
Better hurry up though...I'm moving back to Seattle in 5 wks.
-
...skadamo.....
...he a pretty busy guy these days....
...if we could all meet somewhere in georgia.....
-
I understand my Dad lives there. Axy said he would check in the Crow ate Ya cave complex but I think he was kidding. If you see a tall white guy with silver hair KICK HIS ASS, and tell him Zombie sent you... You'll be back.
48' paper? How COOL. In NY as a kid we would ride (elevators) to the top of the biggest buildings, and set paper airplanes loose all day long. You could find some 4-5 blocks away. I STILL love doing it.
-
..i gots ppl in macon and forsythe...
-
if we could all meet somewhere in georgia
That sounds do-able. Savannah is a pretty cool spot. I know all the dens there. (or some of them)
-
Let's keep throwing this around, and see what sticks.
Bed time... Mommy called. (I mean the Jiz rag)
-
..likes that even better...
:o

Sorry to burst everyone's bubble but there is no way I can make it to Georgia on my scoot.
The DMV is F*cking me hard....at least it's not the DOC anymore!
Gotta stick around Wilmington till I leave for Seattle in about a month.
