So I just rebuilt my motor and blocked off the injector but now I have no idea what to rejet with. Stock carb fmf pipe and soon a k&n air filter in the box and bored .10 any advice would be great.
 
stock pilot, airscrew around 1.5 turns out,
stock needle on middle clip position
i'd start with a 290 main jet, and work down thru 280/270
doing plug chops to confirm until perfect
