    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.

How the hell does this happen?

So what I thought was just a missing bolt appears to be a sheered bolt. Additionally (not sure how I missed it) I noticed the connecting collar is broken. By the parts catalogs I've looked at this doesn't appear to be a replaceable part. (UGH!) Is it is?

I'm going to have to see if I can find a local shop that might be able to back the broken bolts out, but the broken collar seems like it's going to be a trick too.

Thankfully there doesn't appear to be any major exhaust leaks and the pipes 'feel' secure.

Anyone have any thoughts/advice?

This is a picture of the broken collar as best as I could get to it. It's the left outer-most pipe. The break is on the inside-top:

This is a picture of the left inside pipe. You can't really tell from this picture but the bolt is actually sheered off, not just missing. You can see the other sheered bolt just to the right:

Excessive heat then cooling over the years makes them very brittle. pop the whole downtube out of the couppler and slide it off. ive got new clamps if you need them. and downtubes
 
Danny,

The problem that I see is the outside header is welded to the muffler so there is no way to slide that (broken) coupler/collar off without cutting and rewelding the parts (not something I'm crazy about doing but I may have to.

Weren't you planning on a nice 4-1 pipe anyway?

Not me. If I could find some nice aftermarket 'pea-shooter' style pipes that'd be cool, otherwise I'd prefer to stick with stock as much as I can.

Sounds like I need to find a good welder so I can replace the collar, as well as a shop that can back those broken bolts out. Neither of those seem like DIY jobs I want to try to tackle.
 
Are 650E down pipes the same as 650G?
If so I may have some if you are interested.

I'm sure they are. Same engine, just different drive mechanism. How is the condition? Have any pictures? The ones on ebay are beat to crap. (of course I can't expect perfection after 30 years)
 
PM me, I am switching to a 4-1 pipe hopefully today, if everything fits I will have no need for the stock pipes. I'll take pics when the pipes are off.
 
Wait, it is these pipes...

Already cut off to do the Harely pipes. I guess they won't work for you.
 
Nice looking bike! I may have to steal the paint scheme, though I'd go yellow with red accents (maybe).

Those pipes look cool. How loud are they? I don't like the obnoxiously loud bikes.

Steal away, I didn't copyright it. :confused:

I reserve the right to see pictures.;)

These mufflers are very quiet, probably even quieter than stock, but very restrictive.
The bike is slow, the engine has zero top end kick, it runs rich with stock jetting, just a dud performance wise. Hence the 4-1. It's a Kerker, it might be too loud for my stealth philosophy.
Can't imagine pushing the exhaust from a 1200cc twin through these mufflers if they won't flow enough for a 650 four cylinder to run well. Maybe that's why the Herd Tards need such loud pipes to stay alive.
