Very easy to do.

remove the kickstarter lever. remove the black cover and the foot well.

inside the clutch, you will go to the front clutch. there is a single nut on the clutch. remove it.

*****************BEWARE**************

HAVE SOMEONE HOLD THE REAR INNER SHEAVE TIGHT AGAINST THE MOTOR!! Or else all the C VT bearings will fall out from behind and they are difficult to get back in

Once the cltuch nut is off, remove the front cover and sheave together. remove the spacer. reinstall the front sheave and the nut.

Definatly do it. with the spacer in it'll do a whoopping 14 mph. with the spacer out, it'll do ~32 but you can easily cut that back with the throttle.

it's much easier to ride without overrevving the crap out of it. I find it was better for them to have it removed.

Did it tonight in about 20 minutes. Very easy. Agreed, it's a much better ride now that I don't hear the thing bouncing off the limiter constantly. It's much faster like John said, and has no problem pulling my 200 lbs around. My son is actually kind of intimidated {good!} by the new-found "power" and is taking it easy. If I find him going crazy, it's nothing more than a tweak of the limiting screw at the throttle......I thought at one point that I would have the collar machined down to half it's dimensions to come up with a happy medium, then decided to scrap it. He seems to be careful......:eek:

Thanks John, this is great info. I have my son's kfx 90 opened and ready to remove the collar. One question, how do u keep it from spinning when trying to loosen the nut?

Did you figure out how to get it to stop spinning. I am currently at that part right now and cannot figure it out.
