86 GSXR punched out to 1109


Recommended Posts

I bought a half started project and it has the motor bored out to 1109.

So my question is anyone running a 1109 kit with a slip on and air pods? I need a starting point for jets on the stock mukini bst34ss.

The bike starts and idle only with tthe choke 3/4 on.

I saw on this site someone was running a 145 main with .02 but that might be a stock motor.

i know this very dependent on each bike but if the gurus have a better idea that could get me in the ball park it would be very much appreciated.

Air pods and slip on will lean it out a lot ? 

What have you got at the moment in the rack ?

135s mains

I am nrew to carb rejetting. I think the factory pro kit 3 is 145 and one size up on the idle jet.

I hoping someone else may have a setup or an idea to save me some time and money to get me closer to the ballpark I need to be.
