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.

Is a Supertrap 4-1 worth fixing?

When I was picking up a GS parts bike today I was also offered an old Supertrap 4-1 exhaust..

The down pipes are really beat (altercation with the pavement) but it's solid otherwise..

Is it worth trying to fix the dents?

I left it there but I'm going back in a few weeks to pick up another GS so I can still grab it.
 
If you were in Australia, I believe it would be worth it.
Personally, i like the look of a supertrapp, and i would pay for an old one in good condition.
I dont know about the US?
 
I always figured you would have to make a tool to fix them, some way to wedge a split ID matched steel ball to expand it and push the dents out. It would have to be on the end of a flex shaft. I think wall thickness is a real issue on old pipes they are thin to start and all of them have rusted away quite bit of the wall. At least around here in the great white north.
 
depending on your ability you could cut away the bad section and weld in new i would think...tough part would be the bends..i saw someplace on the net where you could send your pipe in and have it fixed...for the life of me i cant remember where...old age setting in.

No, send it to me.....
I smacked mine hard enough to split the collector on one of those fuel tank lids at a service station. I brazed it up , that lasted a year.
I took it to a guy who can tig weld stainless, He gave me 5hit for fLIcking with it, but fixed it for $50. He said the worst part was cleaning out the bronze. That was 7 years and 40000 km ago.

I have heard you can put water in the pipes and throw it in the freezer, the ice expansion will push the dents out. Might take a few freeze/thaw cycles. Don't know if it works, never tried it myself.

Might take a big freezer too.

I've heard of people doing that with dented tanks also. I also have never tried it myself.
 
do a search, sometimes it works sometimes not; one of the great GS mysteries :?:

OK that gives me ideas.. I wonder if you could fill it with sand and pack it in to drive the dents out..

If all else fails I can tig in some patches..

I'll be sure to grab it when I get the other bike..

Thanks for the ideas!
