    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. 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.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    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.

DUNSTALL STYLE MEGAPHONE MUFFLER do i have to adjust the carbs all my bike has is a trait pipe with no buffle.
another question at idle what revolitions does it has to be at.
thanks
 
First things first my friend. What bike are we talking about? what if any modifications to the intake are we talking? Stock, jet kit, air filter or cones?

If you're currently running straight pipes with no baffles and stock otherwise ( carbs and aircleaners), putting on these muffs shouldn't make a tremendous difference other than making things quieter. The air mixture will change a bit going toward the richer side so you may need to lean things up a tad by turning your air mixture screws in a smidge but I wouldn't fiddle 'til you try them.

If it is a stock bike you might even find it runs better with these muffs.

Slap 'em on and lets see what you get.

Cheers and good luck with the project.

Hi,

Most GS bikes idle at 1050 rpm, +/- 100 rpm.


Thank you for your indulgence,

Again, the bike model will affect what you decide to go with, BUT some people (myself included) have walked into their local HD dealer and walked out with a set of stock HD pipes (several different styles available) for FREE. It seems that many HD buyers have the stock, quiet pipes removed and replaced before they ever leave the dealership, and the dealership winds up with a pile of pipes nobody ever wants.

When I walked into my local dealership, I explained that I had an old UJM ("universal Japanese motorcycle") that I was trying to find replacement mufflers for, and that I had heard that if I asked nicely they might have some discarded HD pipes lying around that I could try experimenting with. Five minutes later I was walking out with two pristine mufflers which, ironically I never got around to putting on (they went to somebody else).

Chances are you'll need to rejet after putting aftermarket pipes of any kind on your bike, but at least this gives you more options...

Good Luck and

Regards,
