Do gas tanks grow over time? I have a Sherco and a Fantic. On both, it looks like the distance between mounting holes has increased. The distance could have grown up to 1/2". The tank material does not look like the poly used in Jap bikes. Is it nylon? Nylon does absorb moisture over time so does it grow? On the Sherco, this affects the fit between the tank and fender.

It has been quoted to me to be one of the side effects of running race gas.

Not saying true or false, but have heard it more then once from folks I trust.

Probably polyethylene,

Most plastics are not chemical resistant.

Yeah they could grow, move and not fit right.

Not a big surprise, just a big pain sometimes.

My 2000 has the same problem, the rear fender has been trimmed and the mounting screw for the fender and bottom of gas tank starts at an angle, I also had to drill a hole just above the stock hole for the top mounting screw, it ended up being a slotted hole but works well enough.

I always blamed the poor fit on the fact that the previous owner had a big crash and broke the frame piece that comes off the shock mount and the 2 rear holes for the fender attach. This was welded back in place and I assumed it was just a little off.

I run 93 octane pump gas, not sure what previous owner ran.

Maybe my next step is BIG HAMMER!!

or a Beta

Kinell if you can get Zippys wife to buy him a beta or even gas to get to an event once in a while or even a new pair of socks then you are a god!

When my socks get old I have to loan them to my friends so I can get new ones.

Hey Biff you gonna forget your socks on Sunday?

I know a guy that has a Beta and had to get 60 stitches in his shin from the foot peg. Them Beta's is blood thirsty.

Al,

You may be on to something there!

What have you been using to clean the bike? I have been totally trying to avoid using toilett paper, because the same thing happened to my wife's butt!
