It would be great to get our scoots together and work on them . get them all tuned in perfect . Korn , I'm really glad the uni setup worked out . would you happen to know about how many MPG you are getting ?

I put in a new variator in, however I was wondering what else could be causing the belt to slip? I did put a 1500RPM clutch\torque spring last year which is much tighter than the stock one. For example I cannot press the clutch down by hand, so it is really grabbing onto the belt very very tight. In my head that make sense that it could cause slippage. Should I try a 1k RPM spring? what is your view on this? thank you - Luigi I suspect that the 1500RPM tourque spring you have on is causing the slippage. I would try a nother torque spring, perhaps you still have the stock spring and can try it... If the 1500 rpm main spring is causing the belt to slip , then there is an issue somewhere else. Even a 2000 main spring should not cause the belt so slip. The only way I would expect to see slippage would be if the variator or clutch pulley had oil or grease on them , or if the clutch was locking up somehow , not letting the pulley open like it should. Or if the variator itself was getting caught up while opening , keeping it from opening the way it should. You may be partially correct wilds , maybe the if he would try a loosed main spring , the problem may dissipate some . this could help point towards the real issue. |

Ok I just bought a 2008 "sunny 50" scooter. Further research showed its a gy6 139qmb. Bought it knowing it wasn't quite working right sure but it sounded to me like it just had bad gas and a dirty carb. So I drained the 3 year old gas. Hosed the carb down and it starts just fine. All sounds good and twist the throttle it sounds great....while its on the center stand that is. Once the back tire hits the ground it won't go. Idles fine but give it gas and it just barely gives a small tug. That's it, didn't matter where I place the air mix screw at that's all I get. Going to pull the carb off and tear it down and clean it real good. What I'd like to know is this. My first time with a gy6 carb, any thing I should keep an eye for? And any ideas of what else it could be in this situation? Coil maybe? How's it going? How many miles ? The problem could be a number of things. From the carb to the CVT to the valves needing adjusted. Does it bog down when you give it gas " while sitting on her" . |

Nvm! Didnt see yhat last post. I think il do something similar I have some sheet metal laying around. Im not planning on going for a larger piston unless I need to rebuild my engine so I think my 24mm carb should suffice for now. With my bigger exhaust header and free flow exhaust I went from like 52mph to 60. Iy seemed to get to 60 faster with a 108 jey but I didnt wana blow it up so I went to 110 and It takes a long time to make 60. Hopefully with the uni and a114 or115 it will get to 60 faster. ill be happy with that honestly. Maybe in the future ill use a 28 or 30mm carb but if I can get it to cruise at 60 a little better with the stock carb ill be happy. When this engine craps out maybe ill get a bigger cylinder intake n carb who knows. 30seems like overkill on a stock motor but who knows maybe it would help. Anyone else running a 30mm without a big bore? Honestly buddy, I think these scoots should come stock with a 26mm carb. So if you plan on staying with a stock bore , I'd at lease go with a 26-28mm carb. I only have a 58.5 mm bore compared to the stock 57mm bore, and I'm running a 32mm pumper carb. |

Found the issue. Removed the intake manifold and I found the O ring smooshed a bit and off.. Used 2 dots of grey stuff to hold it to the manifold and she is all set. Taking her to work tomorrow You will probably need to drop the main jet to the 125 , since you were sucking in extra air from the manifold leak. |

I always assumed it would be better to have the fuel filter before the shutoff valve to prevent a clog. My scooter came with the filter after the shut off valve and I never changed it. Perhaps I will get some fuel line and change that setup in the near future. What up bigmac !! , just buy a manual shutoff valve . they are much more reliable. |

What way is better? Do yall think? And thats exactly what i was going to do i have my filter and a carb i can take to the store and make for sure. In my opinion , the uni setup with the homemade intake is Better . it pushes the uni out further towards open air. The heat from the engine moves backwards , so the filter that is right against the carb will pull in more heat . cooler air is always better. |

How's it going ? I made a couple for some members . here is what it looks like.  You can get the parts at most hardware stores. Except for the uni. There is an ATV shop and a motorcycle shop near my house that sells the uni filters. |

Kenda's are good tires , by I always buy shinko's . I've never tried any other brand so I cannot really say which is better. I say , as long as you buy a reliable brand , you Should be riding smooth !

I thought u meant the farm truck always racing those types of cars. I was surprised the foreign car did as good as it did, although it still got slammed. No, Im referring to a local Squid in a Acura Ive handed i his arse to. Lets just say his computer shuts it down at 131mph. on my CBR or in my Porsche they feel some need to test me. I'm getting bored waxing there arse weekly. I'm gonna start racing my scoot , lol |

There is a chance the voltage regulator went bad . I would recheck all the wiring , and if every thing seems OK I'd go ahead and replace the voltage regulator. You can always check the regulator to see if it is putting out as much voltage as it should. If you end up just buying one , and it's not bad , it's always good to have a backup , and they are pretty cheap?
