Re: Gas tank
I'll take a stab. Over tightening any or all of the four studs that hold it to the frame can crack a weld. Other than that use something like Teflon tape on the petcock threads and don't forget the lil ol gasket washer thingy. All I do it place a section of cut garden hose under the tank in the frame cradle and snug the nuts so that I can't easily move the tank left or right with my hands. Can't see the hose, saves my paint, takes up some vibration and tank is secure.
