Hey guys,

Trying to get the bike tuned a little better,

Right now from at Idle when I give a large throttle blip there is little response/ the bike almost dies. I cant be a bit more gradual and its ok. Same for once I'm at a bit higher RPM. Fuel accel pump is working.

Currently only non stock jet is Idle jet Size 40
No Vacuum leaks
stock airbox and exhaust

What could you recommend in terms of jetting or adjusting IMS to help the bike out?

Should I also be checking the carb sync after changing IMS screws?
