So, here is the story.
I had a 380SX and love the bike. I saw a good deal on a 380exc and decided to jump on it. The guy forgot to mix one ride and it seized. I picked it up for $500.
I asked a couple people what to do and they all said just get it replated(it is all aluminum). Not only was it seized, there was a small crack in a port. Munn racing said no problem about the crack they just weld it up. So I got it fixed, put back together, and took it out riding. I was riding easy, just to break it in. After a few hours it was still working perfect. It was running cool, getting plenty of oil, and then it seized. After taking it apart it looked like it did when I bought it. Completely scraped cylinder and there was a crack in another port.
I don't trust this jug anymore. I think the best thing to do is get a new cylinder or get a steel sleeve.
What are the suggestions? Any places that have good prices?
