Clarke Tank Question?

[Boomhauer]

Okay guys I got my clarke gas tank in today and came up with 2 problems one of which I really don't like.

1st off my bike is an 04 and the pet cock has an o-ring on it. The tank came with a flat rubber gasket. Which one do I use? I installed it using the o-ring and the Gas Gas factory bolts instead of the bolts and gasket that clarke provided.

2nd problem is that the shroud bolt that came with the tank is rubbing the heck out of my seat cover because the head of the bolt is so big. So have you guys had the same problems and how did you fix it?

I like the tank and it does not get in the way of my steering damper.

Thanks,
Boom
