125-200cc WR125 to CR ignition mod - notes

Kelly,

Only difference was the ignition and pipes?

Hi All,

Thanks for the tips (yes, it is for my WR250), now just to find someone who sells a flywheel holder!

Thanks all!

You can use a piston stop to hold the crank or a poor boy piston stop is a piece of cotton rope fed through the spark plug hole just be careful not to start with the piston down far enough let the rope get in to a port.

A paper towel left down in the airbox by the back of carb works too! It sux it in nicely!

You dont need a holder to get it off, just the airgun with proper size socket. To tighten put it in a high gear with the brake on.

Any updates with this? How is the new KTM ignition parts working out? I'm thinking of doing this on my '06 WR125.

The KTM stuff worked fine, but the after-market stator quit after about 5-7 minutes of the first race out west. I put a genuine Husky stator in it, but it no longer had the lighting coil. We sold this bike a couple of months ago to get him a WR250. At that time we put the unused 125 cylinder back on it and the WR ignition. The remaining 150 seized at the end of he fist lap at the 4th race out west. I put the 150 off the sold bike onto this one and we still have it. I may even put the WR ignition back on so that my son can use it to go to work. That's the reason we kept this one, because it had the street license.

We got the 250 because the western races were brutal. 2 broken bikes were all we got out of it. Even though 150's are allowed, there is not chance they can compete. Pat was the only pro rider on a 150 and he had to kill it just finish the laps in the allotted time. They had times tests straight up a hill. Talk about unfair. Most horsepower won every time. As much fun as these little bikes are, they can't hold 9 minute hill climbs against a 250F. So now he rides a WR250

BTW, I did have a chance to test the KTM vs. Husky module. There was no difference in performance.

Has this setting for timing been corroborated?
