Wowee

I think it’s time to remove the carbs, disassemble them, and do a proper and complete cleaning. With the tubes out, you need to also clean their passages.

That’s actually what I was working on while i was pulling those out. Air screws, slow jets, emulsion tubes, all that Jazz. Blew them out with the air compressor, poked the goop out of the tiny holes, etc.

Didn’t get those new plugs yet, so the other part of this process will have to wait.

Got the bike back on its own two feet and rolled it outside so it could see the sun for the first time since December. Also so I could clean up the work area a little bit.

What happened to the paint?

Scramps · « **Reply #180 on:** June 03, 2018, 04:59:48 AM »

There were some really bad runs in the paint, so I sanded it back down to try again. I think I’m gonna try to find something a little closer to the color of the 750 I posted a while back, the yellow I had was a little too bright. Also there’s some dents and pitting that need to be addressed

Found a couple of wires that had pulled out of the connector for the coils. Thought my plugs were fouled, but they weren’t firing because they weren’t getting a signal.

I’m going by O’Reilly for a couple sets of plugs for testing tomorrow after work. We have a commercial account with them and they pass those discounts along to us, which is pretty nice.

calj737 · « **Reply #182 on:** June 04, 2018, 02:30:31 AM »

A weak spark will ignite the fuel, but insufficiently to burn it all, so that fouling is definitely a byproduct of poor voltage. Nice that you've found a simple repair to a serious problem.

One of my carburetor bowls developed a leak during the disassembly, cleaning, and reassembly. No biggie, just a squished o-ring.

I put my kickstarter on, had been ignoring it.

I'm having some difficulties with the clutch cable. I can't seem to be able to make it actually depress the clutch, and I haven't had much luck finding any information about setting up the actuator to make it do its job. I either get it so tight that it can barely be pulled, or so loose that it has no resistance.

The push rod is intact, and the ball in the actuator is still there.

Really enjoying your build thread Scramps. Bikes coming along nicely

Scramps · « **Reply #185 on:** June 14, 2018, 04:37:18 PM »

Thanks, crazy horse! I’m enjoying building the thing.

But about the clutch lifter, I’ve installed it as is indicated in the original shop manual, but it’s not working. I’m going to drain the crankcase and pull the clutch cover to make sure I didn’t screw something up or miss a part on it.

Dave500 is needed to chime in if Calj doesn't. PM Dave...

CLR can clean up brass, just don't soak it a long time, 30 minutes loosens up the crud on brass usually, fwiw.

Scramps · « **Reply #188 on:** June 17, 2018, 10:34:53 AM »

I haven’t even had a chance to get into the garage all week, and the coming week doesn’t seem too promising. Thanks for the tip RAF

Scramps · « **Reply #189 on:** June 20, 2018, 12:28:35 PM »

I don’t think that it was the culprit, but I am ruling it out; a large portion of the dividing wall that divides the inside my sprocket cover was broken and missing. I had thought that it wouldn’t be a huge issue, but now I want to fix it. I have ordered an intact replacement, along with a factory air box, which will change some things for my carburetor setup.

I’ve been rethinking several of the design choices, namely the paint scheme. I took a little time today to try and restore some semblance of smoothness to my side covers after I mangled them several weeks ago. They don’t look amazing, but they don’t look like a horror show anymore.

I sanded and cleaned and primed and painted them white for now. This will be a base layer for something else.

Feels good to be working on the bike again! I can hardly stand to be away from it for long.

Scramps · « **Reply #190 on:** June 23, 2018, 07:09:01 PM »

Okay, so, pulled all my components out that are supposed to move the clutch. From what I can tell, I’ve got all the things, but I am absolutely not an expert. Does anyone see anything amiss? Any help would be very much appreciated

Scramps · « **Reply #191 on:** June 25, 2018, 05:33:48 PM »

My apologies, I know that the clutch lever is a perennial issue on the 500s and has been discussed endlessly over the years. I should have done some digging before I pestered you fine folks with the same questions that have been asked a thousand times.

Scramps · « **Reply #192 on:** June 26, 2018, 07:55:10 AM »

Would I be better off just swapping everything over onto the 550 bottom end that I’ve got?

calj737 · « **Reply #193 on:** June 26, 2018, 08:31:42 AM »

Nah, because then you need different clutch cable and rear mount on right side. Just fix it, you’ll be fine.

To Dave’s point: what worn out female thread doesn’t suffer some lateral play when you’re moving in-out?

$:-\$

On that note; does the rod in the picture look to be the correct length? Size does matter in a purely functional sense here

Looks stock length.

So I’ve been on a kind of forced hiatus lately with all the hours I’m having to work, and what little time I have had to work on the bike has been rushed and in a state of exhaustion.

I know I can figure out this clutch thing and get everything back on track, but today I had another annoying setback. I put the clutch cover back on the engine and put some oil back in the crankcase, and of course that cover is now leaking like a sieve.

I’m strongly considering cutting my losses at this point, but I know that would be a foolish mistake. Instead I’m going to try to take an actual hiatus, if my brain will allow it, because I’m going to end up breaking something important if I keep working on the bike in brief, rushed sessions while sleep-deprived.

Godspeed to you all in your endeavors, and I’ll be back sooner or later

calj737 · « **Reply #197 on:** June 26, 2018, 05:39:21 PM »

A real sign of maturity; to take a break when things go badly. It’s jot rocket science, but often the solution eludes you from staring it in the face for so long. Take your break, come back refreshed, start anew, and it will all fall into place.

Another magnificent YouTube channel to watch if you’re into building motorcycles is BMCO (Born Motor Co.)

https://www.youtube.com/channel/UCsJU17u9dqtsG8Dy7VF067A

It’s these sped up time lapse close up shot videos of bike builds (mostly trackers) by this Spanish guy. They’re mesmerizing to watch

DurangoCB · « **Reply #199 on:** June 29, 2018, 05:13:36 PM »

That’s maybe my favorite YT channel. The sped-up videos are good for however it is that my brain functions. Love all the little fab parts and brackets he makes.
