Bolt and sleeve Identification

I have obtained a bucket of bike parts for a 1986 VFR 750. I have most of the bike together and running but cant identify the following. At firt I thought it may be off the swing arm or shock assembly but I have those items all together and cant see where this bolt may fit.

 

I can assemble 86 VFR chassis components with all the hardware in one box. I have no idea what that is.

 

That's great because it at least puts my mind at rest that I may have missed something.

 

The "sleeve" looks like a piston wrist pin that was just slid over the bolt. The other stuff, no idea. As far as the bolt, knowing whether it was a 6mm or 8mm might yield some clues.

 

the white plastic spacer does not belong on a vfr. the bolt and bearing look like parts of the shock linkage.

 

My guess was that it was a small end rod bearing and that it went with the wrist pin. Don't know for what machine. Gonna know right away if it's from this engine, rofl.

 

Thanks for all the input. My guess is it came in the bucket of parts by mistake as there were a few other very obvious items not related. Engine has been swapped out for an other engine as the original one was seized. Bike was put away in 1988 with a 1/4 tank of gas and key turned off at 10,000km . Mice got into the air box and destroyed it. they got into the carbs and the bodies of the carbs were damaged so badly I had to get a new set. The cylinder and #2 piston was corroded so badly most of the top of the piston was gone and everything locked up. I'm putting it together to run test everything first to see what else is needed to bring it back to original.

 

rodents bit your ass, man.

if mice get into your airbox for a long winter nap, their pee is very acidic and will destroy any metal it touches, carbs, valves, pistons. with a partly open valve the airbox pee can drip onto a piston and seize the engine solid. not to mention biting through the airfilter and filling the area with peanut shell and sunflower seed fragments and pee-soacked unidentifiable debris.
