automatic kick start freewheel upgrade

What framenumber do you have on that 250 Auto? Is the engine an 2085 or a 2078?

motor for sure is 2078 I know the frame number shows up as a 250 wr I will look and post it later

Guys,

If your cranks and drums are galling.

Have you thought to lap the drums to the crank shaft?

Like people are lapping the magneto flywheel to the crank on early bikes without a key way.

I always give it a gentle lap every time I refit. Never had an issue.

I have 2078 on my 250 Army, Is it a army model you have on it then.. 14 hp or is it a WR/CR cylinder on it?

Frame number is wn11088 the top end is a wr and a wr pipe had to have been built this way as it has never been apart, shows 233 miles on the vdo, it was only used for enduro for a couple of years then sat from 1985 till I got it

With a galled taper I lightly file off the rough spots that are rolled up metal on the tapers surface. Then it's emery cloth to sand it as smooth as possible. I used high spot red and black on the mating tapers to see how close they are. This shows up high areas and low areas. You scrape the high areas till there pretty much equal with the rest of the taper. The final fitting is lapped. Both mating tapers need to be fitted together.

Be aware of the engine case numbers, I ran into this online buying a engine. The seller advertised it as a '82-AM- MP 2087 that a military police 250 auto. There's a listing on a '81/'82/'83 430 wr/xc numbered 2087. I purchased a 430 but it was advertised as a MP 250. I seen it was a six speed and the pic of the exhaust port showed a bigger bore than a 250.

Buyer beware I see guys selling the late '70's / '80/'81 cylinders and calling them '82/'83'84 there ac but the reed box I'd different and the base gasket is different. The base gasket sealing on the blocks are different they do not interchange. Again know your husky years and parts.

i have a 420 auto and the kickstart has never been an issue . dont know what is inside it . its is likely not stock as the bike came from sweeden and has lots of trick bits .
