Just bought my Sherpa.I bought this bike for the reason that it could be tagged. I used to ride an xr250r and liked that suspension very much. The suspension on the Sherpa seems a little soft in the front,what might be a good fix for that. I also ran across a posting about air box,jetting and exhaust mods. Has anyboby done any of these? One of the mods was to drill out some part of the exhaust, will this make the bike to loud for those decibel tests? Thanks for any help.
