If you've demickey'd then you should do full length fibrosleeves. If not or until then I'd suggest that you move them back towards the end of the pipe.Well I did the debaffle, demickey, and then I followed your instructions for the 6" fiberglass baffle thing. I had a slight issue however because once I wrapped the wire mesh and the 1" fiberglass packing around the 2" pvc pipe it wouldn't really fit inside the pipes that well. It was too tight a fit and I had to really push on the pvc to try and get it in there and the fiberglass kept sliding off the wire mesh because I guess the fiberglass was getting hung on maybe the sharp edges of the old baffle plate mounts. So anyhow, I took the pvc out from the wire mesh, I just rolled the wire mesh a bit tighter using my hands, then I wrapped the fiberglass around the wire mesh as I held the wire mesh in it's rolled position. Then with the help of a friend hands, I was able to get the wire mesh and fiberglass inside the pipes. I pushed the 6" fiberrod up to within 2" of the 3rd plate and it is sitting rougly 3.5" from the end of the pipes (if measured from the bottom end of the pipe).
The sound is a little deeper than it was without the fiberrod in there, but wow what a difference in total from the stock baffled sound. I did notice however that now when I am riding and I let go of the throttle quickly I will hear a little pop or backfire once in a while. Is this normal? is there something wrong with the fuel/air mixture from doing this mod?
everything else on the bike is completely stock and it's a 2006 m50
