hopefully someone has some experience and can tell me if any of this sounds right. ive rejetted my carb probably 15 times in the last 3 days and im running out of patience. 03KLX125L, white bros pipe, no air box lid and a 26MM procycle carb. i can not get it to run right no matter what jetting combo i run. i like to think i know what im doing but this thing is fighting me like no other. im currently running a 35 pilot and a 112 main with the needle on the leanest setting. i cant open the throttle wide open from idle no matter what jetting i run, thinking its a lack of vacuum. i got it running pretty well my house which is at about 600ft elevation. took it el mirage in the high desert and it was VERY rich in the mid ranger but still idled great and ran great wide open. went to the leanest setting on the needle which helped tremendously and made it rid able but was still a little rich in the mid range. now i got home again and its so lean in the mid ranger i can not ride it but it still idles great. so now my questions, is it flat out to big of a carb for a stock internal motor? do those jet sizes sound close or do i have some issue in the carb somewhere? ive cleaned it twice thinking there might be something plugged. thinking about ditching this carb and putting the stock one back on. one more thing i forgot which confuses me, the main jet should play no roll in mid throttle power right? everytime i swap main jets i have to play with the needle again. it seems to change the mid range a ton which doesnt seem right to me.
