Okay, i have a yamaha 250 that i just bought like 4 days ago and the engine blew that night. I dont want to part with the machine so can someone tell me what i should do about it. Ive been told to bore out the engine and others have said to get a new one but i dont know where to get one and perferably thats what i would like to do is get a new one because i have the money and i love the threewheeler so if someone can tell me what they would do then that would be awesome thanks. anyways if any other info is needed on the matter message back!
