If it is an 85-86 model then throw that DG pipe in the garbage where it belongs and put on a Paul Turner Hi Rev pipe. The DG silencer is OK, I haven't ditched mine yet. Also did you raise the compression at all? I run 215-230psi (150psi is stock)on 114 octane race gas, compression will make the bike alot snappier off the bottom revs. Definitely a noticeable improvement. Lastly I'd say put a bigger carb, I run a 39mmPWK on mine, don't believe that B.S. about it being too big for the woods, I rode mine for years with a HiRev pipe and "too big" a carb through tight woods with no problems at all. When it is time for a rebuild again then I'd consider a big bore but I am not totally convinced that they are worth it yet, I think the extra RPM's and smoothness of a standard bore make a good argument for the standard bore.
