If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Hey there gs'ers, got a question...i got an 86 gs 1150 efe and a Vance Hines 4:1...today i took the clothe wrapping off the baffle , just to see what it would sound like....and it sounds awesome...but is this bad for the bike or the pipes? I just got them and I'd hate to ruin them with discoloration or anything.....thx
 
i HAVE A 4/1 PIPE ON MINE AND THE FIBERGLASS IS JUST FOR ABSORBING OR MAKING THE SOUND DEEPER. i DONT THINK IT CHANGES ANYTHING BUT THE SOUND. iF YOU LIKE THAT SOUND THEN TAKE THE BAFFEL OUT ALTOGETHER AND ROCK THE WALLS 8O 8O :D :D
 
I have the same pipe on one of mine. I run thier performance baffle. It sounds and runs better. The more open the baffle the leaner your engine will run usually. A more open baffle usually requires a step up in main jets and possible move on your needles.

baffle

what if you can`t remove the baffles , can you drill more holes in the end to make it louder ? someone told me you could do that , just wondering , thanks :oops:
 
The main difference with the performance baffles is the hole in the center and inner tube that the fiberglass wraps around is much bigger. The result is less back pressure and better flow. I`m not sure drilling holes will help a lot.

i have done that on more than one bike and found that it doesnt usually effect anything but the sound. One thing that i have done is to stick a steel rod into the end of the muffler and knock out the small restriction that is usually welded into the system. It is usually just a washer that is tack welded there on the end of the tube--inside .
 
Well I took the fiberglass out and cut it down to a quater of its original size and I wrapped the very start of the baffle , cause i found there was abit of a metal on metal sound from where the baffle touched the pipe. So the end of the megaphone has no fiberwrap...this gives me a good balance i find...loud but still a deep sound. Also when i took the fiberglass out completly it deffinitly leaned out my settings , but all seems good now, didnt need to mess with the carbs at all...and thank god, cause I've spent countless hours finetuning those damn things :wink: :wink:
