They don't sell dope in London?

Sheesh I be out of a job!

Oldrusty, I just picked up a spare parts bike, plus my other one. They are both 80's but I bet the fuse system is the same, I'd be more than happy to send one your way if you'd like. I plan on converting my main ride to a blade system as soon as I can come up with the dough. The hardest part will be getting it to fit physically, electrically it really should just be plug and play. I think Evolution (correct me if I am wrong) is making blade fuse swaps for bikes, you could check with him and see if he has done the one for the 650's yet. Let me know if you need any other stuff, if it'll fit I'd gladly sell it to you for a real fair rate. Just hate tripping over the stuff.

Thanks for the offer. I got a fuse panel off eBay last night. Most of the other parts I need are specific to the 79. I'd love to find a parts bike, but no luck so far.

Next on the list is part of the seat hinge. I need the bolt and piece that keep the pin from sliding out of the hinge. I think I may also have a wheel from an 80 b/c it's 16". Anyone with a 79 care to tell me what size your rear wheel is? I'd like to find a nice pair of Z wheels, but I'll use what I have for now.

As far as the rear rims go, between the spoked rims and the mags, the spokes are 17" and the mags are 16". USUALLY.

Any recent pics of what you got going on?

Kit and I found a guy in AL that rebuilds stator/rotors for around $70 each. He's on ebay. Go look on her rebuild thread. She posted pics on the difference just this week. It's amazing and the bike charges like a bull now.

There is a guy local to us here in OR that does a really nice job on building new regulator/rectifiers for a great price too, I think around $100. That one is also in her thread. Very nice work and guaranteed for life. Plug n play and much better quality than original.

Good luck.

Yeah, i read her thread updates at least once a day. I saw the pics and it does look 100% better. I'm going to see if I definitely have charging problems first before I drop that kinda cash on a R/R and stator. I do prefer a modern plug n play replacement versus NOS or used.

Western Hills Honda has a parts list. The wheel is just listed as wheel. The tire is listed as 4.50H17 and also lists a tube for it?

?? Why would they list a tube tire with a mag? The clymer also lists the 79 having a 17" rear wheel. As far as I know the only two wheels on a 79 are the comstars on the US version and the mags on the Z version. I didn't think any of them came with spokes.

Not much to really show in a pic yet. Just a few parts taken off. I think I've settled on not using the Vetter fairing so if anyone needs one, let me know.

I feel your pain, the CB500 was a bit of an odd duck, carb kits were expensive compared to all the other bikes, and nothing else seemed to be swapable. At least nothing I was looking at

79 came stock with 17'' Comstar on the rear and inner tube.

Found some parts this weekend. Got another 79 650 that is complete. It's actually in better shape than mine, so I may end up using this one instead and stealing parts off of my bike if needed. It had the usual charging problems, but the PO already had the rotor rebuilt. As told by the PO, all it needs are top end seals and gaskets and a good carb cleaning. I took some pics and will upload them tonight. The deal also came with a pretty nice 78 750F and a basket case 80 750 DOHC.

Here are the pics of most of it. There are a couple of milk crates full of misc parts too.

First pic - 79 CB650

Second pic - 78 CB750F

Last three pics - 80 CB 750

Man you guys get some deals, stuff like that comes up only every couple of years over here and then they want gold for it.

I definitely can't complain about the deal I got.

RM81 · « **Reply #38 on:** July 19, 2009, 01:24:35 PM »

Melted CDI's

Cracked Coil

The next few are to give you an idea of the general condition the PO left the bike in.
No breather hose from the air box to the cam cover. Can't wait to get in there and clean that out.

Carbs leaking and a bad attempt at a repair.

Ran out of electrical tape. Why not throw on some packing tape. Almost as good as the duct taped headlight.

Can anyone tell me what's wrong with these bowls? Makes draining 1 & 3 a little bit of a challenge.

Yeah, 2 and 4 are in the wrong spots!

I realize most of us are shadetree mechanics, and heaven knows I've pulled some facepalmers, but sometimes you just have to shake your head.

Wow. I've been looking over our 2nd project CB650 and thinking, no one did much of anything to this. Didn't they even attempt to take care of it? Now I'm thinking... I'm so glad they didn't do much to this.

At least I don't have to look forward to discoveries like that. (I hope

)

I wonder how the rest of the carb parts were put together?

Hush · « **Reply #41 on:** July 19, 2009, 03:34:46 PM »

Yum you got your work cut out for you there.

razor02097 · « **Reply #42 on:** July 19, 2009, 06:14:22 PM »

wow... Honda even stamped the bowls to tell you where they go... At least he got #2 right

RM81 · « **Reply #43 on:** July 19, 2009, 06:17:43 PM »

Not sure if it's due to the bolt in the fuse panel, but most of the wiring I've seen needs replaced. I'm on the fence about making a new harness. If I could find a new one, I'd buy it but that ain't gonna happen. I'm hesitant to get a used one on eBay b/c you never know what you're going to get. So I'm left with making one. I've seen some sites for the connectors. Anyone have any sources for the wires? I'd like to keep the same color patterns as stock to help possibly save some frustration later on. I think this is going to take a long time and cause me a lot of headaches.

This is the point where I kick my own ass for selling my only running bike. My riding season is officially over and it's only July.

RM81 · « **Reply #45 on:** July 19, 2009, 08:25:47 PM »

Done for the night. Taking the carbs apart was easy. We'll see about putting them back together

. All the fuel joints were leaky so I figured I should replace all the o rings. I'm also going to inspect and possible replace the fuel joint between 1 and 2 that the PO tried to seal. I'm not sure if the brass joint had a leak or if it was leaking from the o ring, but the PO sealed the whole thing. Here's how I left it tonight. Pay no attention to the mess I call a garage. Everything has it's place and I know exactly where everything is (usually).

If you need help re-assembling the carbs let me know... been there done that

The_Crippler · « **Reply #47 on:** July 20, 2009, 12:42:10 PM »

Here's my two cents on the Windjammer faring: I had one on my first bike. I was a lot more nomadic in those days, and it really helped on long days on the highway. I was a lot less wind-fatigued than without. That having been said, it was about as aerodynamic as a barn door and made me feel like I was driving a two-wheeled car.

So, there's a give and take, there. If you decide to go with it, I think I still have a Vetter radio/tapedeck + housing I'd be willing to part with. No idea if the radio works, but the housing's the important part - you can always mount something else in it, I'd guess.

Thanks for the offer. I'll see what I can do first. Found some carb kits on Z1 for $32 each. I'll check that fuel joint tonight to see if it's busted. I don't see anything visible from the outside. I'm hoping it was just leaking o rings. If it is cracked, solder or jbweld?

If you can do it properly I think solder would be the way to go, but I think JB weld is a lot more rugged than people give it credit for. The key in either case is going to be prep work, getting all contaminates out of the area.
