Re: Weak-Sauce Acceleration
if your bike ran great for a week, and then started having the same problem as mkingsley's, there's no way the main jet could be too big for the carb, unless you've changed it.
it's not like your bike works great one moment, then thinks, "y'know? i don't like this jet. i'm gonna stop working good.."
look for an airleak, if it's the same problem. you might wanna check the fuel flow, too. make sure it's not clogged up with rust or dirt anywhere.
