KFX 80 cheap performance tricks
 

Looking to improve low end acceleration for my son and have a couple of follow up questions.
When removing two rollers and cutting the clutch shoes down to 180 grams what part of the shoe am I cutting the weight from?

Do I use the same springs?

Do you recommend shaving the head .030 in combination with the clutch mods.

Thanks in advance

Yes, shave the head.
Yes, same springs.
Your going to cut the shoe off approx 1/2" from the contact pad.

Thank you for your repeated help.
