Hey Guys, I've been checking out this site for awhile and decided to join and ask a question that's been nagging me.
I recently bought an '82 GS750T with about 35,000 miles on it. It didn't have the airbox so I installed a dynojet kit and pod filters and aside from it running just a little bit rich it's running pretty good.
Initially, I was having a little trouble with cold starting and I attributed that to it running rich, but I finally decided to do a compression test and I was getting in the 90's all the way across, so I thought that this might be a contributing factor as well.
After a wet test all the way across, it looks like it is the cylinders that are leaking compression and although I don't know the service history of the bike, judging the guy I bought it from I am pretty positive the engine has never been rebuilt. Also, there is a nice ring worn into the top of the cylinder.
My first question is this: Does it sound like the next step I am planning on taking in boring out the cylinders and going up in piston size and rings sound like a logical next step? I like to do whatever work that needs to be done myself, but I will have to take the cylinder somewhere to do this.
And if that is what I should be doing, I live in Mississippi, and I have had to do a considerable amount of calling around to find someone who even does this. Most mechanics want to send it off and I know I would be paying much more than necessary.
But I finally found a shop about a hour and a half away that will do it and they charge $68/cylinder in labor and they charge an hour per cylinder putting it at about $272 total for the boring alone. Does this sound reasonable, or should I keep looking for a better deal. This isn't a stealership and I've heard good things about the work they do, but I don't want to pay more than necessary. I only paid $300 for the whole bike!
And sorry, but one more thing, I have priced OEM pistons and rings and wow! Any ideas where I can get a deal on some pistons and rings, not necessarily OEM, but they should be of decent quality.
Thanks!
