I have a 2007 Kymco Super9 2T AC 50cc 2 stroke scooter and I am
haveing trouble getting it to run right, I bought it from the original
owner and it was not running right when I bought it, it was running
weak and had low exhaust presure so I thought the pipe was stopped up so I put a new leo vince pipe on it and that did not fix it so I ran
the compression on it and it only had 80lbs on it so I took it apart
and it had a broke and missing ring in it so I bought an airsal 47.6mm
bigbore kit for it and it is still running weak so I have checked the
carb and it was clean and look like new then I changed the cdi box the
coil and the stator and flywheel and there is still no change in it, I
have also checked the plug and it looks good and it has 145lbs
compression, I also put a set of 5.7 rollers in the variator and it
was already derestricted and the belt and clutch and variator all look
good, the only way I know how to discribe how it is running is like
one of those cheap 4 stroke chinesse scooters, it does not have the
quick snap like most 2 strokes and it will only run about 10mph up hill and about 30mph downhill, I have 2 of these scooters and I
changed to parts off the other one to test with, does the scooter have
any other electrical parts that could cause it to run weakly and do
you have any other suggestions .
