The 83 XR5 I bought a few weeks ago is LOUD. It has a Supertrap. I got a rediculous deal on the bike and I've done all basics, oil/filter, air cleaner, LED tail light, full suspension lube, fork seals. Should I try to find an old stock muffler or is there an economical aftermarket alternative. I still need to go through the carbs to get rid of a low end stumble when pinning the throttle from low revs, shouldn't be a big deal, if I roll into it slowly into the low/midrange and pin it it's awsome...just received a factory manual in the mail. I want this thing QUIET. If I can shut this thing up I'll be able to ride just about anywhere here in NM. Thanks.
