Gotta love it when a bike cooperates this well. Its just a little gem and has been nothing but a pleasure to work on so far, despite a couple challenges. Just goes to show how good we could all have it, in a world without idiotic previous owners. Everything I have inspected on this bike appears t o be untouched.

Sean, big congrats to your bike!
I have exactly the same recently. That green is really special one

Really nice write up and very good looking 500

seanbarney41 · « **Reply #28 on:** May 19, 2019, 12:59:47 am »

Thanks guys...it is a 550 though...not that they are very different.

Ain't nothing wrong being a 550, always been my favorite. It's getting really hard to find them in that condition anymore, no rust, seat rot or faded paint... and unmolested.......almost like buying her new. Great find!

seanbarney41 · « **Reply #30 on:** May 19, 2019, 07:00:25 am »

Thanks for stopping by, RB. You are definitely THE 550 guy.

The candy jade green paint is in such good shape, too.

seanbarney41 · « **Reply #32 on:** May 19, 2019, 11:02:31 am »

I have not even cleaned or polished the bodywork yet. I will certainly try to post some quality "golden hour" pics when I do.

BRG-BIRD · « **Reply #33 on:** May 19, 2019, 06:06:45 pm »

Oops, my bad! Sorry

Stev-o · « **Reply #34 on:** May 20, 2019, 07:39:45 am »

Nice score Sean! I'm a 750 guy that loves 'the middleweights" too.

That looks like one Eric would have picked, how'd you find before him?!

seanbarney41 · « **Reply #35 on:** May 20, 2019, 09:29:56 am »

Heh heh, Facebook market place tends to bypass various old curmudgeon buyers. Ordinarily, that would include me too. But I got people looking out. Plus, Eric don't got much love for the little bikes.

Tews19 · « **Reply #36 on:** May 21, 2019, 06:53:12 am »

Wow! Impressive survivor there and she cleaned up really fast!!!!!! What's the plan now Sean?

seanbarney41 · « **Reply #37 on:** May 21, 2019, 09:43:11 am »

I want to enjoy some riding, take it to a couple shows, then sell. I got a lot more 750s that need the space! Also, it is not finished yet. I need to find a number 1 323 pipe and a grab rail, and some other small parts.

Stev-o · « **Reply #38 on:** May 21, 2019, 03:03:24 pm »

Those pipes pop up on ebay all the time. I'm sure you know the CB500' uses the same ones.

Here's one that has a crazy price but make him an offer?

Member Dave has a #2 listed, maybe a #1 as well?

So...i grabbed a number 1 pipe off ebay. It's not in great shape, but the baffle was intact (or so I thought). I had a welder friend braze up some damage with silicon bronze. Then I noticed the baffle was very neatly drilled. So still sounding like a thumper single

only wasted $60, and $60 More for the brazing

seanbarney41 · « **Reply #40 on:** June 28, 2019, 09:39:01 pm »

I went ahead and mounted the new pipe anyway. Splashed out for some rather approximate repro exhaust collars sold by 4 into 1.

seanbarney41 · « **Reply #41 on:** June 28, 2019, 09:52:15 pm »

Sooo, I guess I better fix the front brake. The master cylinder was totally packed with a substance that resembled, err, well, mud? So I bolted up a working spare. Found the bottom brake line clogged with a similar substance. Stabbed a long wire through and got it to squirt across the shop, then flushed the lines clear with brake cleaner.

seanbarney41 · « **Reply #42 on:** June 28, 2019, 10:10:12 pm »

I really want to rebuild the master cylinder that came with the bike, as the anodized finish is in close to the best condition I have seen. I bought a Honda oem kit and carefully installed it, but so far the master cylinder won't build pressure. So back to the trusty spare.

Yeah! I really feel like Michigan is one of the best places in the world to be finding these old bikes. They just keep turning up. Really happy I get the chance to save another one.

they really are endless here

Just saw this...very nice find and good luck sorting out the brakes.
Too bad about the MC...
David

seanbarney41 · « **Reply #47 on:** September 30, 2019, 09:27:22 am »

Yeah, I tore the mc back down again, found nothing amiss, put it back together, and now it works. So that is cool. Actually the first time I have successfully rebuilt an mc.

You are better than me. I just go the re-pop route on the CB's and the Kawasakis...
