new to motor bikes
Hello all im kinda new to this i have just aquired a schwinn mountain bike from a good friend with a flyinghorse 66cc engine kit. I helped build the bike from the start and he kinda lost interest so here i am. i have been doing some modifacations to the bike over the past few weeks in hopes of finding higher speeds but so far most have been like back steps i curently have been fighting with a cns carb i have it set as lean as it will go but it still is running so rich it bogs on top end. i have not replaced the stock exhaust yet but as soon as SickBikeParts gets some in im planing on getting a expansion chamber. any help would be much appreciated.
