Default Re: Riding in hilly area

Depends on the carb you have, the stock china one will be ok as long as the jet is properly sized, a good starting point is .o26" or a #72 drill bit, put s drop of electrical solder over the mouth of the jet, don't fill the whole thing, flux it and try to fill just the tip, a quick shake while hot should remove exxes, then take the drill in a micro hand fixture, twist the drill into where the old hole was, slowly, keep the drill even, roll the drill until it goes thru, make sure ya get the shavings out before yer done. The stock carb does NOT have a mixture(air) adjustment. Hope that helped.
