Ok, I know that the bluing on the pipes is due to the lean mixture...and I know that there are products to take it off...to that's been covered.
However, here's my story: I bought my bike from a dealership, used. It had 412 miles on it...but lately, I'm beginning to be a little suspicious of the bike history.
For one thing, when I took the bike to the shop for the belt adjustment, the mech there asked me several times if I'd ever replaced the rear tire. I told him no and told him where I got the bike and the mileage...
Second, and this is my question: The discoloration on my pipe, up near where it attaches to the engine is NOT blue, but gold. Somebody told me that means the mixture is too rich. Is that possible? Is it possible that my carb has been modified and I didn't know it? How could I know?
I don't have a lot of backfiring issues but there are some. When I stop the bike, I get a little muffled "poot", and I've only had one real shotgun blast all season.
Any thing specific I can look for without taking anything apart to know if modifications have been made?
EDIT: Oh yeah...my bike is a 2003
