Pressure test that coolant system to make sure the bottle, hoses, and radiator are good. You can get a test kit cheep at auto parts stores.
Had a couple Busa's...so far. Both had little/to nothing for coolant in the overflow tank when I got them,never had a problem.
If the paint is comming off in sheets,I would guess it was done poorly. I'm no expert painter but it sounds like a lack of flex agent and/or the use of an' adhesion promoter or blocked out to smooth or blah blah blah. This might be a good time to fix all the body work. Sanding costs next to nothing and has only one draw back. One arm get bigger than the other.
Just me maybe,but I'd be tempted to fix all the plastic now,before spending more money on that one planel,only to have it come off as you say "In Sheets" later on.
RSD.
I was going to say the same thing about his paint but didn't want him to feel bad because he said it was a $3000 paint job, lol. Sorry to say bud but IMO, you (or whoever paid that much) got ripped off on that paint job ;(
The good thing about a lay down is that you get to play and experiment with things. Look up how to plastic weld the cracks, sand it down and paint it yourself. It will not be perfect because you're not a pro but it will hold you over until you can afford to replace the plastics or pay for another pro to paint it. Have fun.
lucky for me i didn't have it painted or pay for it, just have the receipts. i got the bike from a repo company, and other then checking title, frame to make sure its straight and adding gas, haven't had to do much.
