Here's some more DOHC CB trivia.
The 750/900/1100 all use a different style of ignition advancer. The 750 is on the top, 900 middle and 1100 on the bottom. The 750 has 2 weights on one side, the 900 has one on each side and the 1100 also has 1 weight but it is lighter so it will start advancing sooner.

I don't have many pictures of Old Yeller. I came across these pictures on a forum I used to be on daily before FB came along. It was my 1st attempt at a road race bike back when I still followed Mr. Hyde. These pictures were at Willow Springs in 2015. My good buddy Phil Buie came along for support. This was my 1st time racing. I had Dennis Parrish race the bike. Unfortunately it didn't last long. I learned the oil pump doesn't like 12,000 rpm for very long. Live and learn.

I used to race motocross. I'm on my custom made 1980 CR480 that I built in 04 with the help of some good friends Jay Lael and Nobby Toledo (RIP). I used an '80 CR250 frame and many parts and the engine from an 82/83 CR480. She's a ripper for sure. It eats Maico490's for an appetizer. 🤔😁😎

In this album I will do my best to show what I will be doing to install this ignition. I am not a tech guy so if you see me messing up feel free to share your experience with this ignition. I don't care what you did with your Dyna 200. I have messed with plenty of those. Lets stay on track and maybe all of us will learn something and get a better running CB-F.

This is what Ignitech supplied me with. I needed the connections to connect it to my laptop and they supplied the connections at a good cost IMO. I have also had them send me a TPS (Throttle Position Sensor). Because of the TPS. I decided to also buy their universal wire harness. It is capable of doing way more functions than I plan to use. With the addition of the TPS. I can turn the ignition into a very simple 3D system which is way more accurate than the mechanical advancer on the bike. In the middle of the picture is the billet piece I got from RICCI Engineering out of AUS. Ignitech does not supply this. I also had to drill and tap the throttle shaft end for the carburetors. Then make an adaptor to control the TPS. You can run the ignition with all of the OEM parts as they are. I wanted a bit better for Hugh.
I will keep adding to this album as I go about it all. Stay Tuned.

Ok, here we go. This will be my 1st Ignitech ignition and I have chosen to make it a simple 3D ignition. I have to add a TPS to the carbs to make it 3D. I will also need to make the wire harness for it. They sell a universal 22 wire harness, so that makes this a bit easier. I doubt I'll need all of the wires. I'll find out shortly. Stay tuned.

Here's an FYI on the CB750 and CB900 clutch covers. If you are experiencing clutch issues? You need to look at the fine adjustment bolt. If it is not nice and round on the back side and is looking like a mushroom??? The adjuster bolt will need to be replaced.
It should look like the one I am pointing too. I have seen quite a few that got destroyed at some point.
I hope that helps some of you out.

Here's an FYI for the people with 83 CB1100F US model bikes. If you need a new wind screen. Look for an 82 CX500EC one. They fit in the same hole. I will have a link to the place that sells them in a couple days. Picture of the bike in the link.

Im getting the next engine for Ken Kenneth Roosa ready to be steam cleaned. I needed something to seal up the exhaust ports so I don't get water in the engine.
These plugs will do nicely.

The rain finally went away so I got 2 good 4 mile rips. My Gopro didn't want to play so this is the best I could do Hugh. It does WeeWee's.
💪👍😎

Today it was time to fire off Hugh's engine. This is the 1st crank. Freaking AWESOME.
