Jetting question.

[DannyMotor]

On my GS750 project the po had short pipes and a dry k&n filter installed. they also had 120 main jets in the carb. The vm carbs ran 102.5 as stock in 78' as the info chart on Basscliffs site suggests.

I'm going to oil the filter and run a 4-1 headder system. Are these jets going to too big to tune properly?

Thanks in advance!

Your 120 might be about right, as a starting point. You might have to raise the needle too.
