all the motors turn over. The parts bike motor gurgles, so it seems the head has some rain water in it . I decided from the get go that I wanted to tear the motor down, if for nothing else, just to learn. But also you have to realize that these bikes are 35 years old! I have no clue when the last time was that they saw combustion, and I have no idea why they were left by the wayside. Just because they turn over, doesnt mean all is well. I could fire it up and seize it right away.
All that being said, I did find some fun in the motor that Im nearly done taking apart. I got the head and cylinders off and took out the pistons. This was a few days ago and I set them aside to be cleaned since they had a bit of carbon buildup on them. rings moved freely and did not catch. All seemed well. Today I took the propane tank to refill and while I was out by the garage just took a quick look at my progress. I picked up one of the pistons, and wtf... a HUGE chunk is missing out the bottom of it, lol. I do have a bunch of metal flakes in the case, but I thought this was simply from the camchain roller/tensioner/guide being worn down. It may be, but nonetheless the chunk of piston is nowhere to be seen. So I def have to crack the case open and see what I can see.
So I may have to use a lot more from the parts bike engine than I had planned on.
Btw, thanks for the support chase. Youll def be getting some pm's from me when I get stuck. And thanks for the autozone tip. How exactly does that work? I just leave a deposit for the tool? I was about to go buy a honing tool, you saved me some $$$ it looks like. But as far as the hot tanking goes, I think I still want to get the compressor/blaster. It will pay for itself in the long run Im sure...
p.s. I have zero experience with this stuff. but Im atleast slightly mechanically inclined, so Ill find my way through to the other side.
