What ever lenght you had to the front subtract that from the swingarm,i.e. +2+1 a-arms put a -2 swingarm. That way you move weight off the noise and get it towards the back for traction. Get nerfs, killswitch, better handle bars, wider axle +2 or +4 and 20in front tires and 18in rears, change your gearing to suit the tire sizes. PRACTICE
