This blog is chronological description of my 78 CB750 chopper project which I began in April 05. SOHC (Single Over Head Cam) CB750 motors were produced by Honda from 1969-1978.

Quiet spell...

Its been pretty quiet in the shop the last couple of weeks. We were in NC last weekend for Thanxgiving. Maybe I'll get some pics up of that. However the weekend before I put a couple miles on the chop. My next step is rejetting. With the straight pipes and pod filters I need to put larger carb jets to make up for the increased air intake. I've got the jets, and hopfully I'll get that done this afternoon. I also mounted the FZR rear wheel I have. It looks good and I think I'll be able to use it. Its gonna take a litte fab work, but nothing major. New spacers and a brake arm should do it. However for now I'm gonna stick with the spoke rim I have. Maybe I'll get the FZR wheel on before the Mytle Bike Ralley. Also in the middle of changing the head gasket on the stocker. Hopefully I'll have it on the road in another week or so. I also bought a 77 Supersport a few weeks back. Its up in Arkansas waiting for me to pick it up. I'll head up there in a couple of weeks and pick it up. I'll update with some pics ASAP.

Cheers!!!

Day 224-Maiden Voyage

Yesterday at 1414 hours Central Standard time it happened. I took my chop on its first ride. I think the last time I posted the motor was running, but I had some cylinders that were not firing. So last week I pulled the carbs that I rebuilt and put the carbs from my stocker on the chop. I knew these carbs were good and clean. After putting them on, the bike started with no problems, and ran great on all four cylinders. At this point I just had to get the wiring in some sort of resonable configuration so the bike was actually ridable. Jason came over Saturday and we got the bike off the platform. I bought a battery and charged it overnight. Yesterday I cleaned the wiring up and tood it for a spin. Didn't go far, just around the block, and barely got into 2nd gear. The chain was slapping against the fender when I got over 15 or 20 mph. The motor felt good/smooth, with a little popping out of the #4 carb. I can probably remedy this with the air/idle screw. Front brake is VERY spongy, so I won't be going very far or fast until I bleed the front brake. Turning radius is a concern. The handle bars hit the gas tank pretty quick. My goal for the weekend was to take it for a test ride. I accomplished that so I got no worries. Ground clearance is horrible. I have maybe 2". Dragman from the SOHC board says he has a used set of MAC drags...hopfully I get get'm on the cheap. The MACs should run paralell to the frame and should give me a full 4/5" of clearance. What else? Kickstand, seat and gas tank mounts, forward controls, rear brake, head/brake light wiring, coil mounting...I think u get the idea. Still plenty of work to do, but, its on the road and thats motivation enough to get me through this other stuff.
