Good luck with your project. Selling some of the extra stuff will pay for what you are doing, or part of it anyway.

At least that r100 went to an inmate. I bid on it to try and revive Jo-Nathan's r75.

Where are you located in Arlington? I'm in the Del Ray neighborhood in Alexandria. I'm slowly putting together an airhead project bike, might be interested in some parts once you have leftovers.

On the right side cylinder the the cylinder seems okay but it has been burning slightly hot their is evidence of detonation at the top of the cylinder their is a little bit of scoring on the walls as well but not as bad as the other one the left.

The bike will shift into gear but it will not rotate at all meaning the back wheel or motor is completely locked up also the bike has a small oil leak as well."

So the engine is toast from what I read. However, I picked up a 82 r100 frame, engine, tranny and drive train from ebay for $950 and I'm gonna port everything over this winter. Should be a fun project.

Gonna have a ton of /7 extra pieces this winter so be on the lookout.
What does "Blown Rings" mean?
I've seen them broken and worn out but never "blown"....maybe the mechanics terminology for "shot"?

I'd go as far as questioning his qualifications to work on anything that goes suck - squeeze - bang - blow -..........

The good thing is, your damn motor can't read. If it says oil on the container, it's pretty much OK to dump in there.... ED.

Hmm. I'm pretty hands-on, so I'd be inclined to just tear it down myself and find the real problem(s).

If it does look like that...unless you want/need the experience, don't even bother with the tear down except to get good parts. You've probably got metal bits in all the oil passages and pump. If oil pump gouged, block is gone. Rods are probably frozen on the crank, bearings seized, etc, MAYBE good lifters.

Take your new engine, put a set of new rings,,,maybe a timing chain - and ride. Use the old block for a door stop.

Ouch. This is what happens when you figure that the noise will go away if you ignore it...

Makes me wonder how long that one was run before the owner got tired of the noise and lack of power.
