Nice, perfect post. I know you will, but be sure to post back what jets you go with. Plan on doing an actual dyno tune or butt dyno tune?

Probably gonna butt dyno this bad boy because I’m cheap but I’m reading into wideband o2 sensors, that would be interesting to try out.

Had some grime on my kickstand lever and exhaust flanges so I brought out the big guns. A 17 year old can of oven cleaner. The older it is the better it works, right?


Came out vomit green


Turned brown, looks tasty.

Was also able to polish out some deep gouges on the stator cover.


Before


After, used a die grinder with some sanding and scotch brite discs

Currently working on shortening the wiring harness about a foot to relocate the block connectors that were in the headlight bucket to under the tank. My new headlight has no room to fit anything inside.

That Easy Off oven cleaner looks like my cat's vomit!! I hope it works -- the cleaner (not the vomit)!

Managed to relocate all the headlight bucket connectors under the gas tank




No fitting issues, nice. I’m planning on moving the ignition switch to where they’re  located on the early CB’s, under the tank.


Hooked up some front turn signals and a couple of handlebar controls I had laying around. Gotta get started and finish the front fender and brake to call the front end done.


A delivery? For me?


Wow, thanks USPS. It was a crankcase cover gasket, luckily it wasn’t bent too bad.


I was digging around a crate of parts that came off the 650 and found this. A spacer of some sort. Anyone know what it is or where it goes?

Could be, but it looks aluminum. Might be the oil filter spacer.

Last post are the measurements.

Yeah that would explain why it was a bit oily. Put a new filter and some oil in the engine a couple of days ago, don’t know how I forgot this, thanks!

Another quick dumb question.


Does the exhaust hanger bracket fit in front of the passenger peg mount like so? Or behind?

It appears to be fine in front of it. I suppose you could bend it (gently) to mount behind it.

And you may need to use that bracket on the right side pair. I seem to remember there’s a locating pin so you can’t just flip the bracket. But I only checked out my 650’s exhaust for about 20 minutes and then trashed it during the tear down process.

Thanks for all the insight guys, very helpful.

On another note, I burned out my 1 week old $9 starter solenoid. I guess you get what you pay for.

It’s been quite awhile. Took a break from my project and was able to get back to it the last few days. Did some little things like cutting the front fender and stripping the bad paint job on the rear fender that a previous owner did. Gave them both a brushed finish because it’s better than rusty scratched up chrome.





Decided to try to turn it on once again with no luck. I was really working against myself using old gas and no air box. After fitting the air box on the carbs I was able to get it running! It’s idling a little rough but I still haven’t synced the carbs, hopefully that will clear the issue. Not gonna lie, I’m pretty proud of myself for turning an old junker into a running machine. Still need to rebuild the front brake caliper and sort out a tailight situation to make it road worthy but hearing it run for the first time relit the motivation I have for finishing this.

Drilled and tapped a hole to relocate ignition.


Slapped on the front brake caliper after paint and rebuild. Used a braided line and got rid of the splitter. I can only assume that this bike used to have dual calipers due to the splitter but I only received it with 1 caliper and rotor.


Also sanded down the airbox side covers to match the fenders and painted the side covers black to spruce it up a bit.


I was able to take the bike on its maiden voyage around the neighborhood a couple of times. No issues with the zx carbs and fuel delivery. No smoking or backfires, all seem well. Takes about a minute of choke to warm up but afterwards it purrs like a kitten. Couple minor fitment issues, boots from airbox to carbs are too big. I had to ditch the metal clamps and crank down some zip ties to get them to seal, haven’t looked into a replacement yet. Also the airbox won’t bolt onto the stock location of the frame, it would be sitting forward about half an inch. I could fix these issues with airbox boots that are longer and sized appropriately.


Next up I’m gonna see if I can do anything about the seat. Might cut it down or something to have a slimmer profile. The tank needs some attention too with all the small dings, missing badges, and scratches....dry rotted tires too, looks like my wallets gonna get a bit lighter.

Maybe zx airbox boots and a custom breadbox?
Then the mounting is all up to your choosing.
70CB750 has a simple design on hos 750 that is both co pact and light using stock airbox boots. Maybe something to look into.

Bad news, had to call a tow.

After a couple highway miles I met up with traffic, pulled in the clutch and started to downshift. The revs went down and the engine shut off. Wouldn't crank over afterwards, seems like the battery died. Will check it out tomorrow, hopefully it’s an easy fix. Maybe regulator/rectifier?
