I just got an 87 Zilla and I can't wait to ride it. As of right now it is missing the silencer and the pipe is shooting hot exhaust on my leg (The pipe directs the flow right at you and man does a zilla have back pressure!!!) Its a little too dangerous to drive considering that every once in a while it backfires flames through the pipe when you go to kick it. I don't even want to mess with it until I get the silencer so I know its safe.

P.S. I have a silencer on it but the pipe is short... I think it was taken off a 500 mx bike or something cause it has a bigger bore than a 250 silencer. It just is about 2 feet short of meeting up to the stock zilla expansion pipe that my quad has so basically its there for show and does absolutely nothing.... the guy that sold me the zilla said it needs a connecting pipe between the expansion chamber and silencer but I just think its the wrong silencer and he didn't know what he was talking about. The expansion chamber is definitely the correct one though.... a 500 pipe is unmistakeable!!

Thank You for your help
