#27790 Greeny (User) Expert Boarder Posts: 502 Exhaust flutter 5 Years ago   The Samson Shotguns on my 06 Silverado have an irritating flutter on decel. I have the Samson baffles installed. Stock carb and airbox. I haven't touched the carb or PMS. Would taking out the baffles tend to help reduce the flutter? It doesn't sound bad, but I know it can sound so much better. I'm also thinking about just changing pipes as I haven't been very happy with the Shotguns. The slipon portions have an ever increasing gap between them and the head pipes. Plus, the upper slipon turned gold the first long day after installing the pipes. However, 500 miles in 100 degree heat on the way to Sturgis didn't help matters. Any ideas on reducing my flutter?

Platinum Boarder Posts: 4368 Re:Exhaust flutter 5 Years ago   If I'm not mistaken Greeny.. adjusting the pms helps minimize the flutter. I'm sure someone here will know exactly what to do. good luck   Logged     04 MIDNITE SILVERADO   The administrator has disabled public write access. #27795 Big Bear (Moderator) Who loves you , Baby? Moderator Posts: 6997 Re:Exhaust flutter 5 Years ago   If the AIS is still on the bike, you might be hearing some noise from the exhaust because of that. Flutter=light popping on decel? If so AIS will contribute.BB   Logged       The administrator has disabled public write access. #27821 Greeny (User) Expert Boarder Posts: 502 Re:Exhaust flutter 5 Years ago   Big Bear - I took the AIS off about the time I put the pipes on. blackroadie - What pipes are on your bike? They sure look a lot like my Samsons. Anyone have a thought on baffles vs. no baffles? I wasn't sure if their sole purpose was to quiet down pipes or if they add back pressure as well?

I have Vance &amp; Hines Straight Shots. Baffle sniffle. Trying to pull air back in in the absence of positive exhaust flow. Don't worry about it! Just don't decelerate! Just keep going full throttle til you see God! <br><br>Post edited by: archangel777, at: 2007/05/24 21:57   Logged     Rev.

I have taken the baffles from some pipes and cut about 3/4 of it off to dampen the overal sound but change the tone. Had a lot of pop with my new pipes and found I had an exhaust leak and had to run a double exhaust gasket to fix it. As for the gold color it sounds like the bike is a bit rich, you may have to jet it.   Logged     My bike site If you\\\'re not living on the edge, you are taking up too much room!   The administrator has disabled public write access. #27863 Greeny (User) Expert Boarder Posts: 502 Re:Exhaust flutter 5 Years ago   I appreciate all the help. I'll check for an exhaust leak this weekend. I've always assumed the bike runs rich as it's my understanding most come that way from Yamaha. I haven't messed with the carb yet. I'm getting just under 40MPG on average if that's a sign of running rich too. I've heard of these getting closer to 50MPG tuned right. Tried pulling the baffles out and they're sealed in pretty good. Any good method on removing baffles that have been in place for a year? I didn't want to pull too hard thinking I might mess up something. I remember them being pretty tight when installing. Nothing I had to pound a hammer on, but snug nonetheless.

(a small slide puller works well here) Probably what is keeping you snug is a ridge of carbon built up that you have to get past. I have the same flutter with my Bub Stubbies, and I am hoping that going froma 3/4 in baffle to a 1/2 in baffle will help. Another thing is to pack the baffle with fiberglass or steel wool may help.   Logged     http://www.hellrisercustoms.com/jjsnet   The administrator has disabled public write access.
