i recently purchased a 1996 yamaha pw50 for my four year old. :)
it starts easily and idles good but smokes quite a bit, stumbles at open throttle and there is a little spooge at the end of the silencer. i know running the bike on it's center stand is not the best way to tell but it's all i can do right now plus there is some load from the back wheel spinning. i adjusted the oil pump cable the best i could and the jetting is stock except the needle clip was moved to the top groove. my thinking is that it is rich but i am a novice jetter.
the plug looks pretty clean and brown just a little wet. i don't think that it will bark like carmichael's cr250 but i know it can run better that this. any help is greatly appreciated. thanks.
