Checking ball diff on KF2
 

Hi,

Is it possible to test the ball diff tightness by checking it through the traditional way on the KF an KF2?

This is by holding the 2 rear wheels in place and then blip the throttle to see how far the nose rise up?
I tried it once before and it killed the spur.

Thanks!

The best way of doing it is to hold the LH wheel and spur in one hand and try and rotate the RH wheel with your other hand. then look to see if the belt is moving (belt moving = diff is tighter than the slipper).

Hope this makes sense?

What should it be like i,e tighter than spur gear?

I check mine that way... helps keep the adjustment consistent if you ever replace a part mid race day slipper adjustment easy to duplicate. my only suggestion on the KF/KF2 is to not stay in the throttle for too long. There is alot of strain on the belt

I do the same method as hazeandfizz. The slipper should slip before the diff, you'll kill the diff if the diff slips before the slipper.
