View Full Version : '81 CB650C "Chopped into Coleslaw" build

05-28-2016, 7:21 PM
This is my first bike. I went with a friend that was experienced enough to tell me if the bike was decent or not. We had no idea that this was a 2 year bike and parts are a bitch to get. I dropped $1k on it, which may have been too much to be honest. What I'm planning to do with it has been called "chopping it into coleslaw" by a less adventurous friend.

The sissy bar set-up, seat, mirrors, airbox, and taillight/rear fender had to go. We also pulled the carbs for a good look over/cleaning, and the tank for painting.



When I had the carbs on the table I noticed the rubber "T"s between both set of carbs were rotted out. Once I did some research I decided I was going to make another set as opposed to buying them. When I got to the shop I found someone had already done the job. Instead of running them back to the original hose, a few other guys advised just connecting the set of carbs straight up without running a vent. Now I'm waiting on the pods and jets to get in.


I ripped the emblems off the tank and painted it, and started working on a seat. I've cut it out of a Creature skateboard deck. I'll be padding it up and working up a few other things this next week.

I'm looking forward to seeing what your inspiration produces. I've seen it before but where skateboard seat come from?

@WarMullet Thanks. I'm flying into it with what I have on hand as much as possible, partially because of budget and partially because it's more Mad Max that way. I bought the deck in '06. I don't skate anymore, and I needed a seat. That's basically all of the thought that went into that.

I got some hose from Lowes and cut a line down the middle. I stole this idea from a guy on youtube. The idea was to staple the underside of the hose in place, but I bought wrong staples. I've got 3" springs on the way, and also bought a hinge from Lowes. I'll be adding some cushion (probably a yoga mat) and wrapping it in a few bandannas when I get everything drilled and ready to mount.

Pretty kewl, gives it character. Let me know how that yoga mat ass pad works for ya. Can't imagine anything more than scooting round town, my back hurts thinking bout extended rides like that lol.

Yo do yourself a favor and ditch the seat springs unless you're hard tailing the bike or strutting or just like looking silly

Silly to whom? Builders taste trumps outside opinions. But more to reflexion's unstated point, you may end up doing a tone more bouncing than you want over bumps if you keep your rear shocks. But honestly that's matter of riding preference.

@Reflexion I've discussed strutting with a few friends. I'm fairly short so I think it'd make it all the more easier to ride if I went that route. Not sure exactly how low or how I want that to look yet.

@WarMullet "Builders taste trumps outside opinions." haha Fully agree with you here.

Made any coleslaw yet??

It's been a minute since I've updated.


I changed the jets. I'm running 130s on 1 and 4, and I put 132.5 on 2 and 3. I got the bike to start, but then it was leaking gas from one of bowls and from the diaphragm pump. I ripped the carbs back off and checked the insides. The rubber on the vacuum pump had a slit in it, and the metal was covered in rust. Also the gaskets around the bowls could be in better shape.


The diaphragm pump is no longer a part you can buy, and the gaskets would take me weeks. So, the coleslaw crew did what the coleslaw crew does. I bought gasoline proof gasket sealer and covered everything in it. It took a long time to dry, so I took the time to tackle other projects.

Changed the bars, ripped off the blinkers, and finished the seat. Tomorrow night is go time.

Got everything back together, and she fired right up. Throttle stuck and I had to kill it. Took a look at the cables and noticed the push (return) cable was shot. Another set-back, another part ordered.
