Can any one comment on, or recommend, a good tank liner for my cafe racer project? The tank is very clean inside but the slight mod may have introduced a pinhole or two. The seams seem OK but I'd rather be sure. I have bought some "KBS Gold" sealant but are there any problems with this compound? I'm mod-ing one of my '85 XJ900 bikes to a cafe racer just for the fun of it. I did a search for "tank liners" on the forum but it's really hard to find the references because the ref. doesn't show straight up, just the whole thread (I'm sure the reference would be in there somewhere), or maybe I'm not doing it right.
