omg i am so pissed off. i put the expansion chamber onto the silencer and it wasnt qite right. i cant get it off now. i slightly bend out the folds of the outer shell. i heated it to but theres still the black steel on the inside that is tietly around the pipe. i cand get it off please help!!!!!!!!!!!!! mohave addict!!!!!!anybody.

 

anyway at my last wits end my dad saw a can of wd40 and said males try. and to my surprise after about a minute it slid right off. that stuff is amazing i swear by it now. that my pipe still doesnt fit that good we had to modify the braket and mount it on the inside instead of the outside of the frame bar.

 

you have an expansion chamber on a 4 stroke?????LOL!good luck with that!
