Need Some Jetting Help for 850 BB

[Shonuff]

Just got my BB 850 back from Group K but have a mild bog on the low end that I can't seem to tune out.

Do I rejet? and do I rejet larger?

Add an extra carb.

[Shonuff]

Stock SX-R carbs.

What's your jetting now?

 

[Shonuff]

Stock jetting.

Your are too lean. I would say try 80 low, 150 high, 95 gr spring, 2.0 needle and seat. The stock jetting from Kawwi is pretty lean for a boat out of the crate let alone a big bore set up.

Tune with jets, the low end screw is for idle tuning only. The high end screw can be used to fine tune the main jet circuit for upper RPM mixture.

Why are you not running Harry's True-Bore carbs?
