i have a 2004 yzf250 with full pro circuit t-4 and filter and i think my bike needs to be jetted, or something is sticking or messed up in my carb. it cuts out like crazy in the warm weather. it idles high after i give it gas and then goes back down, it sounds like its getting not enough gas. and up high on the rpms it cuts out and down low when i try to accelerate. when i punch it and when i get on it easy. im thinking a bigger main jet? does any one have any ideas for me?
