2013 Super8 2T
--- 8g Dr.Pulley sliders
--- exhaust "derestricted" by cutting off and plugging the extraneous tubing (yes I did the plug-the-end test and it stalls out and 'pops' showing no leaks)
--- 82 jet installed
--- opened up the inlet box opening from small round hole to about 1" square
now it idles so fast it will accelerate away unless brakes are held,
and when moving, just cracking the throttle a little causes it to bog and slow down,
and cracking the throttle a lot just kills the motor entirely....
great; now what ? I've gone from a usable but disappointing scoot, to a can't ride it at all.....
-
Re-engineer the inlet opening. That opening is very sensitive to dimension change. I have diff size pieces of plastic I use to resize that opening once I opened it up.
Cant rule out a sticking auto choke or whatever that thingy is that can controls RPM's on cold start. Mine revs up fast too on cold start,but mainly when the weather is on the cool side.

Interesting, thanks, I'll try that.
If you search my earlier posts you'll see an "expert" advised ripping the inlet restriction out, even after I asked if the carb needed the pressure drop upstream of it. That's the joy of online forums, all you need to do is sound authoritative LOL

Hmmm from the sounds of it you are blaming me for this mishap? Sorry buddy, I've been working on scooters for 6+ years professionally and more than that on my spare time. You only have yourself to blame when things go wrong, no offense. First off if you opened your airbox you will need to go higher than a 82 main, the 82 main is the "stock" de-restricted jet size. Also did you adjust your mixture or idle at all? All of these things will play into how high the idle is. I've derestricted 2t scooters in the manner I suggest on here HUNDREDS of times, if you don't do something correctly that is not my problem exactly. I can understand the frustration, I've been there, but your biting the hand that feeds you by flaming me for "bad advice".

I'd beat his ass Ian. He lives in Portland!
Seriously now... Easy brother. You were given good advice on what to do, I won't defend anyone but I will point a finger. YOU sir did the work.
There is either an air leak at or near the carb or the idle mix, and / or the idle speed screws are set wrong. The jet you have installed is also wrong. It was suggested to you to install at LEAST an 85.
We don't get hurt feelings around here so please step back, take a breath, and we will help you sort it out if you like.
If you're that convinced it is someone else's fault... sorry to hear this, and I'll see If Kymco will send you a "T" shirt.
What size do you wear?
-
yeah, I fully expected the "you did it yourself" replies from the "advisors"........ blameless in their anonymity
long before I posted I tried 85 and 88 jets, they were worse;
and just because I dont know 2 stroke scoots intimately, dont assume I know nothing;
there are no vacuum leaks, the float hasnt sunk, its been apart several times looking for things loose or come adrift....
dont reply, I'm not coming back to this forum, will figure it out logically myself
-
Everyone here knows who, and where I am. Sorry you feel that way.
-
So sad, instead of raging and blaming others, you could have posted up: "hey this is what's going on" and gotten great help. I don't give a rats ass if you think my advice was wrong, it wasn't and you messed your scooter up. f***ing entitlement generation no damn accountability. How about others that followed my exact same advice CORRECTLY? Oh yeah they are doing JUST FINE!!!!! Like i said before, i have done exactly what I told you to do on HUNDREDS of Kymcos, with perfect results. If you haven't played with your mixture, that's your problem not that I really care at all anymore.

I'm off to on line classes. I'll make a pill to fix all this. (No not the morning after one)

I already got something to forget about it, just have to go pick it up at my friends house ;)

I have read all of Ian7 posts, all 26 of 'em. And all of your replies. I have concluded that all who responded were convincingly concerned with passing valid information to get him going. JUST LIKE ALWAYS ON THIS FORUM. Not that the Zomb nor B&L are gonna lose a lot of sleep over this guy but they gave it their best shot and Ian din't quite "get it" enough to finish the project. We probably won't hear from him again ever but at least he did not start out with, "URGENT!! Help needed! Real fast!"

We love ya Karl.
I did sob for an hour or so but that was for humanity in general. Ian was just the trigger.

Good evening.
I'm going to pass around a plate of warm donuts.
Zoomy please pour the Seattle's Best.
Now that we're all comfy, I'd like to quietly suggest that folks stop buying anything with a 50cc engine ('cept maybe weedeaters) b e c a u s e (calm down, now) b e c a u s e they get tired of going thru life at 28 MPH and start messing with it.
Remember what the great Navajo, Two Sox Standing In River, said before the tribal meeting in February, 1851 : "DON'T Mess-whid-it"!
Would that people buy at least a 125 in N. America.
There'd be a lot less strife on 2 wheels, and elsewhere.
There are very, very few folks in N. America that do "slow" as well as the Stig does.
(I still wish I coulda got that Vino or Metro 2 yrs ago!)(http://i61.tinypic.com/mv4vvo.jpg)
Just sayin'
Stig
-
But Stiggy... Both of my 50's are, less expensive to purchase, operate, maintain, and faster than either of your bikes.
Plus there is something in the "just too cool" factor.
I'm sorry man. I do love ya but your overpriced, slower than a paid by the hour labor hall worker bikes suck!
HOWARD STERN RULES!
-
Stig you nailed it. I ALWAYS try and talk with customers thinking about buying a 50cc and go through everything, make sure they don't want to take the motorcycle class and get their endorsement and have WAY more usability on their scoot. This kid wanted his scooter faster, I gave solid advice, and he did something wrong. I don't know why he couldn't just ask for more help rather than instantly blaming others for "bad advice". Like you said no sleep lost, i deal with this almost every day at the shop, enough that I think it would make a decent reality show lol.
-
Et tu, Bet&lute?
I have another advantage... IF I crash, I am already at the point of impact. Hell my bed is higher than the seat on my bikes.
You'll never convince me that 4-5 times the cost + DMV issues + required classes on riding (been riding for 43 years) + insurance + greater likely hood of hurting someone other than myself + looking like a dork w/ 600.00 bucks worth of AGATT on a SCOOTER is somehow better, safer, more economical, or in ANY way cooler than a bad ass 50cc
It's a lifestyle choice first, and foremost. Like tough guys wearing pink. If you can't pull it off...stay home.

I only say this because in Oregon, you still need a license, insurance, and registration on a 50cc. It only costs $200 for the endorsement, class and all. Don't get me wrong, i LOVE hopping on my 50cc and doing wheelies around the block. But if I'm going across town the zuma gets half the mpg as my 250 and gets there half as fast lol. I love a badass 50cc but MOST people are not like you and I, making a 50cc much less practical. If Oregon was a DUI state and didn't need a license for "mopeds", i would have a different outlook. They make it hardly beneficial at all to be on a 50cc in this state.

Maybe I have to pick my battles better... My apologizes. I'm forwarding my Beer Assistant...

I'd gladly add a Ruckus,Zuma or other easily modded 50 cc , if I didn't have other things to spend hard earned $ on . Trouble is , I would keep spending on it to further mod it .
I have the 300cc so I can visit my Dad 100 miles away and make it to The North AtlanticBlues Festival (every year ) and Acadia National Park ( the roads to get there require something that large , unless you want to be squished like a bug ...Cagers ::) ) .

That is the one downside of 50cc riding. 30 miles is about I'd do in a day. I ride out to EastPoint a couple times a month to eat or for boat parts but otherwise I don't really leave Carrabelle.
One flaw in the armor. :'(
