my 96cr250 just dosnt seem to have the pull it should when im really reving it. over the winter i put boyesen pro searies reeds in, a fmf scilencer and regeared it(1 tooth higher cs sprocket). now the weather is about 60-70 degrees and dosnt seem too humid. i think i have the pilot jet dialed in but the mid range seems like its not right and wot feels lean(revs like mad but the power dosnt seem to be there)i cant really tell if the mid range is lean or rich but im thinking lean. would richining the main a step(180) possibly clean the mid range up a bit(and of course wot)? another thing i was pondering was if leaning the needle a notch and richening the main a step would do anything? where is a good place to find tires? what would be the best rear i could get for gravle pits, mostly soft terrain? another thing is does it matter if you put the master link clip on backwards? i put it on today and rode but didnt realize it was backwards till i washed my bike. sorry for all these questions but knowledge is power( i could use some more spelling power also lol)
