Why do some petrol tank change colour
I have 2 ty monos and one of them has changed from white to a faint rust colour .
I have noticed it is not only Yamahas that do this.
is there something that can be done to prevent this.
I was going to powder coat the frame on my 240 and have moved the footrests and thought I might steepen the fork rake how much do you steepen the forks or is it not worth it.
I there any one with pics to show where to cut.
