i was riding my r today for a little bit and im not sure if it was the cold weather or something but at bottem end it was running fine then when it hit power band it wanted to shut off anyone think it could be jetting if so what should i do?

[86 Quad R]

it could very well be the jetting....what fuel are you using and how old is it? what temp was the carb previously jetted for compared to the temp you were riding last? also, how long has it been since you rode it last.

try going richer on the needle and main a bit. see how she acts then. :cool:
