As the title says...what do ya'll think? The speedo has been broken for several years, and it reads almost 4000...I was thinking that it might time for a top end rebuild.
I know alot of people say if it ain't broken don't fix it, but I'm into preventative maintenance and it seems a shame to redo the suspension, track, and body without touching the motor. I ride alot alone, and can't really afford to have my motor die 50 miles into the woods.
I already deleted oil injection with my own homemade plate, and I think I should rebuild before I blow it up and put a hole in the block. If you look at the piston through the carb mount on the right side it looks like there is some scoring or black carbon streaks or something like that.
Looks like a kit to do gaskets, rings, pistons, clips, etc. is pretty cheap, probably well worth not being stranded.
I was wondering if someone can school me on overbore.
http://cgi.ebay.com/ebaymotors/84-88-91-...dZViewItem I saw this kit, and some others, but it looks like it only comes with one piston? Anyhow...do I want a size up here to accommodate for wear? I'd need to get it bored out at a machine shop, right? Anyone know of a comprehensive kit with both pistons, etc?
This would be my first motor rebuild, but I think if I take my time I can get it done right with all your help, of course.
Thanks!
Jesse
