71' CB500 monoshock with no name...O2 sensor success!

Re: 71' CB500 monoshock with no name...but she runs now (vid on page14)

I've been toying around with some pipes on this. The pipes on it now are cool, but someone gutted and kind of destroyed the "muffler" part of them. I was thinking of running dual pipes up the back a little. Found these duc pipes and thought it might be cool. Eh?

They are cool. I have a single one and am running it under frame on CB450

Nice! Got a pic or a link to your build thread?

^ +1, would like to see how you have that set up. My brother offered me his stock Duc cans and I wasn't sure whether or not to take him up on them (also, they weigh three hundred pounds each)

Yeah, that's the only reason I'm going back and forth on them. I bet they weigh a ton.

The one I picked up is aluminum and titanium and weighs alot less than one of the stock silencers from my bike. I haven't put it on yet, so a pic would be of no help, it's laying on a shelf with a bunch of pipe in my garage.

Hadn't considered that - I haven't hefted the Sportster exhaust I have on my CB450 for a long time, they were probably at least as heavy.

Thanks for the input guys. Maybe I'll go see how much they weigh and give him a price based on that? haha ::)

Well, I found a setup from a Hayabusa that was relatively cheap. $80 for headers, and 4 cans. 1 was damaged, so I started to tear it apart to see if I could make some shorter (and far lighter) mufflers for this thing. So far, it's a no-go. Aluminum outer casing that I can't seem to slip the insides out of. I'm sure I'll eventually get it. But for now. I have adapted the GSXR1300 headers to the cb. I like them, and it seems that I can still get to my oil filter up front without too much trouble as long as the bike isn't too hot! ::) There's a mounting point in the rear of the pipes where it crosses. I've got to make some new collar spacers up front, and then weld a point for it to attach at that X point. So far, so good.

Made my own exhaust collars since I didn't have any to fit this set.

Took me a bit, but I just went through your build from start until now. I'm loving the way this is turning out and definitely like your style. Can't wait to see the finished product!

Thanks a lot. I appreciate it. I hate how long it takes me to get to the bike though. I'm driving down to Georgia for a wedding...so progress won't happen until next week. I'll be starting and finishing the seat pan when I get home Wednesday if all goes well! Thanks again.

I've lived in GA for about a year now. You should enjoy the warmth while you're down.

Dang, just got all of this. We were in Augusta. Great wedding, little chilly, but better than the snow I had here!
