Well at least her innards got another flushing!
Lesson learned.... from now on, close the petcock.

Cool. I'll check it out.

Thanks

id keep a eye out on your oil level for a few and hope it was getting there from the fuel pump not the carbs. It doesnt take long for fuel diluted oil to take out a rod bearing. JB

A little more progress each day, your detail is really impressive.

Thanks. Hopefully fully sorted out when the weather breaks.

I'll keep an eye out. The bike was running well yesterday and I didn't see anything in the intake plenum (not that it would necessarily get there though). There was a significan amount of gas coming right out of the fuel pump when I had it running today, so I'm petty sure that is the problem.

I just went and pulled the fuel pump.







Sorry about the crappy images. I need to get a new camera. I couldn't see any light through the diaphram, but it is cracked and weathered pretty badly. I can see the fiber mesh in at least one 1/2" area around the plate. Oh well. It is dirty under the pump anyway.

I've got a bunch of those cracked pumps. the only use I've had of one was this. Sorry it's fuzzy, I used one to make a mount for an electric pump.

Is that the pump from Randakk's or did you do that yourself?

[Cookie]

It's one I picked up from Ebay. They are pretty standard pumps you can get anywhere. If you use one with stock carbs make sure it is a low pressure as stock I think they run 2 lbs.
The joy of Randak's kit is that it is all developed and bolt on. If you do it yourself you have to make a mount and block off the old holes.

Yeah. I was looking at Randakk's kit after my last reply. I did a bit more research and the 3 fixes seem to be,1. to get a new OEM pump. I'm waiting for the final price, but it looks to be close to 100.00. 2. get a GL1100 pump I guess it has a slightly higher volume, but not too much to push the floats off the needle and have better low rpm fuel delivery. And 3rd go the electric route. I read Randakk's description and the price for the standard kit is $150.00 shipped. I would pay about $110.00 to get a standard OEM pump and I do like the idea of the constant (non-pulsing) fuel deliveryof the electric pumps. Some people are saying that it really does help the motor run better at low rpms. What do you think?

[Cookie]

I think the joy of the electric would be to eliminate the several stalls when starting after sitting a while. My bikes always start but they take some ranking to get fuel up there. We have had about 15 days of rain and my yellow bike did the fire, stall thing over and over like always when it sits. That can't be good for the starter.

Since I need to get the fuel pump issued resolved, the bike won't be running for awhile and I might as well move on to the other parts. The exhaust needs attention. It is basically solid except for the left header at the muffler joint.





The holes are in a good spot to be repaired. I just need to get some thin walled steel pipe, cut off the old and weld on the new. Since I don't have any pipe, I made myself feel better by cleaning up the shields.





Certainly some pitting, but they are about as good as they are going to get. Then I wanted to get the rear wheel on so I could start on the front of the bike.





I think my kitchen sink is going to see every part of this bike except the motor block and the frame.





Then a bit of reassembly.





I got the rear brakes hooked up and working well and the differential fluid changed. So far so good. Then I figured that I won't be getting into the rear of the bike again before the test ride so I started putting the bits back on.





I had to buy some parts that were missing; the seat, pegs, different rear fender and taillight, etc. Everything seems to be good, but I'm not sure about the seat.



It doesn't really look like it fits right. Maybe a later year???

It still needs paint and a few bits, but I wanted to get some of the parts on before I start tearing into the front end. That's it for tonight.

My guess is the seat is a custom one, not bad, looks pretty stock. A number of folks have welded in auto parts store pipe to fix those.

Probably. It's comfy, but I think I'd like something a bit sleeker.

Well, I was debating about getting another mechanical fuel pump or going with Randakk's electric setup. I like the idea of an electric pump and his is nice, but I think it looks a bit out of place for me. At $150.00 a complete bolt on conversion would be delivered to my door. Not that bad considering what you get. The OEM pump would be a little cheaper, but not that much.

In the end I ordered an OEM pump and insulator gasket today. It will be awhile, so still plenty of time to sort out the remaining issues and have the bike ready for the road by the time decent weather hits.

Looks like my '72 CB500 is going to a new home so that will free up the license plate and a few bucks for Gold Member.

I just got a few minutes to get out in the garage today. Got the front wheel off and the forks drained and removed. The left fork had good oil in it...no water. The right fork did have just a bit of water, but it was clear. I'll see when I pull them apart for cleaning and new seals, but I'm hopeful.

The steering head seems tight and uneven when you turn the wheel. I never noticed it before today when I had the front end jacked up. I'll pull the trees and regrease the bearings before I reinstall the fork tubes. Maybe a tapered bearing set???

[Whiskerfish]

The tapered bearings is a very worthy upgrade. You will not regret it. I think I got a complete set from Z-1 for around $30
