Swingarm Assembly to frame 1980 CR 390

Washer against the frame. Remove the paint both in-board and out, same on the front mounting lugs and motor plates also coil mount. If you don't motor will not be solidly mounted and will loosen all the bolts then the swingarm bolt will oblong the hole in the frame, then it will get ugly as will have to weld it up and start over.

Good job George!

Does Coffee have you on the payroll as an expert advisor?

Great advice. My friends dad when I was growing up had the Husky shop here in town, in the back of his muffler shop, heh its a small town. When assembling the new bikes he always took the front engine mounts off and buffed all the paint off of mating surfaces. He also did the same with the coil mounting and voltage regulator mounting also. While he was at it he would run a redundant ground wire from the ignition to the coil. He said it was easier to do that and keep them running good than deal with the warranty paperwork that never paid enough! When I worked for Caterpiller nothing went together with paint between it.

Good tips. I have actually had to add the extra, direct ground wire on bikes that I could not get to run right any other way.

On the older KTM's with rubber mounted handlebars, they used a braided ground strap between the handlebar and the triple clamp so the kill button would work.
