Title: What to do?
Post by: Rottamies on July 27, 2020, 09:17:27 PM

I installed tecnigas next r exhaust and it doesn't do wheelies anymore because the peak power is so high that i cant lift it anymore.
Should i change variator rolls to get peak power to lower rpm?

You did just the opposite of wanting more power at lower rpm. Maybe change out the centrifugal clutch with a higher stall speed where it let's the engine rev more before engaging.

The peak power  with your setupis where it's at.  You can't lower it.  Your best bet is to change to stronger clutch springs. I prefer the yellow springs, others prefer the red springs.  Your clutch will engage with a bang at a higher RPM.
