My sons TTR90 fuel tank has cracked in two different places. Used tanks appear to few and far between. The TTR 110 is much easier to find. I know the bikes are very similar. Will the TTR 110 fuel tank fit on the TTR 90 frame? I know the fairings are different, but I can buy a 110 tank and fairings cheaper than a 90 tank. Anyone have any knowledge or suggestions?
