That is a spacer isn't it?

A bushing or bushings. Theres a space in the center that I can get a punch in, but, I hit several times and even put some heat on it with a turbo torch, but no go. I gotta drill it out, I think. I just gotta get a 23/32 bit.

Parts list shows those to be pressed-in bushings;

Should be able to knock them out from the inside.

That's what I was thinking. Best way to do it would be to get a long punch and from one end stick the punch into the hole until you can get it to hit against the lip of the bushing on other side. Then hit it little by little until you can get a good wacky at it.
Use some PB blaster also.

I hit em and they aint moving. If I'm ever going to have both motors in a bike, then I need to just drill. But, I bought a $32carbide bit and it wont even scratch it. So, I got some abrasive stones for my die grinder and grinding my way thru. Got one side done! Off to the hardware store for some more stones. They don't call me the human milling machine for nothin! :lol:

If you go down to your local bearing shop you may be able to get a set of needle bearings to go in there.

Ugh! Nevermind.

:lol: I gotcha. It needs a good cleaning. When I get the other motor overhauled I'll give it a good cleaning when I put it back in.

yes those bushings are removable and you can buy the proper ones that will fit the swingarm bolt. just buy the bushings for the chassis you squeezing the engine into.  the 465 was made in 1981? those bushing have been in there over 35 years so they will be tighter than the hinges of Hades. If you are dissembling the engine completely remove everything from the cases.put the cases in an oven and then turn it on to 400degrees   do not preheat   remove cases. leave oven on, pop out bushings, pop in new bushings, put cases back in oven and then shut oven off, let cool slowly

not sure if it would even be a problem but the relatively slow heat up and cool down should help prevent warping.

Here's the front  mounts. I didn't realize how much frame mods had to be done until I had the motor out. He utilized the I.T skidbars if you will.

Heres the center bolt. Pretty simple there.

Some mods were needed to the main frame to accomodate the exhaust port. And some grinding of some of the fins. The fins on the head are chopped some to facilitate head removal.

And I never pressure wash my bikes. This ktm has never been pressure washed. It was a roach when I got it a few months ago. 3 different sized brushes, some simple green, soap & water and some elbow grease.

Before.....
