Yoshimura MJN jet kit tuning

[DrRipper]

Anyone knows a mech who's good at tuning a carb with the yoshi jet kit?

double check your FC mileage again then check the simple things first like tyre pressure, chain slack, free rotation of wheels to make sure the wheel bearings are not busted.. then move on to fuel leakage checks before deciding on tuning again since you did it recently.

Checked them all. There is a small leak on one of the fuel pipes (after the fuel pump and split into 4, one of them towards the carbs). It doesn't leak until you touch it. Planning to get it fix.

 

I don't trust the tuning, although the carbs are synced with a flow synchronizer. On foreign forums, there were opposing instruction even on leaning or richening as the needle in this kit is vary different from other kits. Most agree they run great at low and mid, so would rather keep it than go back to stock jets, if possible.

 

Thanks
