Upgraded carbs and no longer need these Keihin VB42A Carburetors from 1979 CB750 DOHC. Bike was a marketplace rescue and came with pod...

Well I don't have anything to compare it to, but staring at it for a while it seems like the lever arm is bent. Was able to find the...

Update: got the RS34 from Ken & Suzi at Cycle X, 10/10 would recommend. I described the exhaust system to them and the current...

I had the swingarm off to strip & paint it, and also installed a new chain and sprockets. When I put everything back together the rear...

Brilliant, thank you both. I did spot the bolt location in an eBay pic after knowing what to look for. I did some ridiculous swing...

So I'm mildly considering tracking down an airbox and reinstalling it, however at least in the manual I've got I don't see much...

Here's said clack, sounds like the #1 area Yah kind of hard to tell right now since I went from running on two cylinders to running on...

Yes I'm glad I found them too, but those carbs were not involved in the reassembly plan haha. I got it running and there's good fire...

So actually they were backwards on #3 also, but that one had at least a little fire based on the plugs. Also the gasket between the...

Also after further inspection the primary jet and secondary jet on #2 are reversed, could that prevent fire? Normally I'd think yes but...

Well I've got the carbs off the bike and I think it's kind of a miracle it ran at all lol. #1 is missing the little rubber plug where...

Nah it will be awesome. My understanding from these forums and others is that even if I get those carbs dialed in, this bike will not...

Yah there's definitely fuel in the bowl on 2, I drained it the first time, and it filled again and has a slow drip leak out the bottom...

No I laid the plugs down in order from the other side of the photo, so they're backwards 4 to 1 as pictured. #1 has 150psi, spark, and...

Well I answered the question of this post lol, motor is a teardown for sure. Have spark on all cylinders, no fire on #2, and...

Definitely no fire on #2, and was not firing before the valve job either. The plug looks like it just came out of the bag. Reverse...

Not 100% sure, before the valves I was more concerned about the smoke, burning smell, and oil streaming from the valve cover lol. It...

Alright so I got the valve clearances sorted on the bike. Everything on the exhaust side is .005 or .006, and one .007, and on the...

Well if you're here and looking, both the JTF339-17 and the JTF339-17RB with the rubber cushion fit. There's way less clearance behind...

10/10 would spend lol, cool idea thank you!

I did a bunch of research to find the right size sprockets to convert from 630 to 530 chain on this bike. got a JTF339-17RB with the RB...

Yah it's twice as many carbs though haha. Maybe I'm just excited about Mikuni because I had triples on my Datsun Z back in the day...

Probably should have specified, looking at the quad setup.
