Hi Guy's
Any tips on removing the primary gear off the crank when doing a bottom end rebuild, Gear Puller maybe ??, Also any advice for fitting primary gear onto the new crank.
Cheers

There are a number of tools you can use. The easiest one to make, is a thick brass plate with a slot cut down the middle. A thin U shape. You slide this under the little end of the conrod (with piston removed). It needs to be long enough to bridge the gap in crankcases and sit flat on the base gasket both sides. This stops the crank from spinning when you turn the bolt on the end of the crank. This works whether you undo it or tighten. The use of brass prevents damage to conrod.

The cheap way is to get a thick sturdy piece of cloth and feed it between the two gears on the crank and back of clutch. This jams the gears and stops everting spinning and you can undo or tighten the bolt.

Cheers

Proper tools on a two stroke is cheating!

Cheers for that guy's,
I have the nut off but cant seem to get gear off the end of the crank. Would heating it slightly help?

Absolutely not! Under no circumstances whatsoever should it be heated, levered, or hit with anything.

Use a puller.
