I think I figured it out. I think it goes between the 2 & 3 carbs and acts as the bottom anchor point for the throttle return spring.

Now one more part I'm missing... There a tube joining carbs 1 & 2 and 3 & 4, and carbs 2 and three have a angled brass fitting that is lightly pressed in. I pulled one out thinking there was an o-ring in there. The second one I don't remember pulling out, and this is the one that didn't get bagged. Somewhere along the line it came out, and I don't know where it is. Shit.

I got my carbs back together today and only have one extra part!

Trouble is, I don't know where it goes.



Any ideas? (it's not hollow.)

Got some work on the frame done yesterday.

Picked up a spare tank from my friend's house to I could stick it on the frame with the seat. I think I might base my cafe seat off this pan, that way I can use the stock hinge and seat lock. Started grinding off tabs. Those two on the left are for the brake light and pedal return spring, right?


Anyone know what this one is for? I didn't cut that one off yet, but I don't think I need it.



I was going to remove the brackets for the center stand and weld the side stand from my other frame onto this bike where it's broken off and taken a chunk of the frame with it, but I'm wondering if I should bother with the side stand and just patch it up. I think a center stand is more handy anyway, and it's not such a big bike that I can't always use the center stand. Removing the center stand would shave a few pounds though.

I also brought the wiring harness home with me so I can start dissecting and recording it. I'm going to make a new custom harness, and maybe a couple stock harnesses for sale while I'm at it if anyone's interested (and depending on some rubber boots).

It's a pretty good looking bike just sitting there on my workbench with a tank and seat on it though, isn't it?

Carbs are just about ready to be put back together with rebuild kits. I cleaned them up with a soda blaster. I think that's been my best cleaning tool investment yet. It put a really nice, almost brand new finish on the carb bodies, and clean up is just warm soapy water.

Ran into a couple problems two weeks ago when I was bolting my case together. I applied the Hondabond and started bolting everything together, when I realized that I forgot to check the torque on the cam adjuster. So I had to take it all apart before it dried. I cleaned everything up and started over. I reapplied the Hondabond, then I misread the torque specs on the M6 bolts, and broke the M6x100 and had to tear it apart again. I put an order in for new M6 bolts, and the should be here Monday.

Today, I went to my dad's shop where the frame is, and had a visualization session. I brought out the frame and stuck a tank and seat on it to try to figure out what I wanted to do, and where everything is going to go, and what tabs I'm going to grind off. My conclusion was, stock tank (there's a CL350 tank on it in the pic), custom seat, scrap the center stand, battery box, side covers and air box. The only problem is that the plastic bit from the carbs to the filter box is thin because the outside two carbs are pretty close to the frame. Will pods fit?

It's a good thing I went to check up on my project! I'm been working quite a bit on my engine sine the last I posted.

The cam cover and side covers are polished, head and cylinders are clean, and the cases are painted. I have one stubborn bolt that didn't want to come out of the bottom half of the case, so I've had to drill it out and am waiting for my uncle to return from China so I can bring it into his machine shop and drill it out for a helicoil. Other than that, the engine is ready so go back together, and it will be time to start on the frame.

I was about to order an alternator last week, but I already have one! It's in the pic at the top of the page!

I moved into a new house with a big, under used basement, so I have my own workspace now. I hope to have a lot more progress this winter.

CB400F Project

I decided to start a blog for one of my other projects, my CB400F, which I got along with a parts bike from a friend about a year ago.

Below is what it looked like when I got it. Just a bare frame with an engine.

I also got a parts bike with a nearly complete engine. This one had a bent frame.

As soon as I got them home, I dug right into the engine. The top end is removable while in the frame. I actually think that you can't get the engine out until you take the top end off. (I'll have to remember that when I'm putting it back together.

Top end off, with pistons sticking out.

This is one of two oil pumps. It's only about 2mm thick, and as big as my finger. I think this one oils the top end, and the larger one oils the crank shaft.

The case is split open. From the front, you see the crank with connecting rods, the main chain from the crank to the transmission. The basket holding the clutch plates has been removed from the right side already, and the left side is the output to the final drive chain to the rear wheel.

For the last month or so, I'm been polishing and cleaning all the external engine parts and rebuilding a set of carbs I bought on eBay.
