Picked up a 2001 Yamaha Dradgstar 400m one exhuast is getting the blue look on it. I'm told that it is running hot more then likley because of a lean fuel mixture.

Is there an adjustment on the carb. or does it require rejetting?

Free advice - normally there is not an adjustment. rejetting is normal way.

Thanks next step is trying to figure out how to get a Thai mechanic to understand that. We do have several good mechanincs here but some times communication can go very wrong LOL.

Maybe the approach would be bigger jets ?

Well it's good to have friends a friend came over today and checked the bike, turns out it had two different kinds of plugs in it, the side with the heat showing up was a hotter plug. Changed the plugs back to the original specs it's running fine and the problem may just be solved.

So what do you use the clean up the blueing on the chrome?
