I have a chance to obtain a 1982 Yamaha XT550 for free. The bike runs and all parts are there except for the turn signals...which is fine as i am not interested in a road bike. The owner has the title and rode the bike last year. Here's the problem.....at the point where the engine bolts to the frame on the top end, the engine is cracked and leaks oil. The owner sealedit with some epoxy and rode it all day with no problem. The epoxy then cooled and came loose. He took it to a local salvage yard looking for parts and when they did not have what he needed, he basically gave up.
Parts seem pretty available through the internet so I am thinking of taking it and trying to fix it. First, what is this part called? I know , I am completely lost when it comes to engines but I am not worried about learning.
And, am i wasting my time with this bike?
