I got the wiring done, my only question was does white/yellow go into white. My factory service manual came out of the plastic bag but I saw no yellow in the diagram except the dyno and ign switch I think. I do have a Pamco but it all terminates at the coils. Anyway everything seems to work. Next, I tried to put on the headlight, I was sure the old one was tweaked and I'd nick paint so I used a new one I had saved for such an occasion. I left the halogen light assembled but off and put on an old Stanley sealed beam.
I gravity bled the brake with towels covering everything painted.

Just then I heard the front garage door make a loud noise and went up front to check. A torsion spring broke and unwound pitching off the cables. Menards has the correct one in stock so that's my tomorrow project.

I added fuel to the freshly cleaned carbies and they're spewing gas. At minimum it's the o rings on the fuel tees. I let them dry out over the winter. Bwwwaaaah.

Next up, testing the petcock rebuild.

I've never replaced those O rings Don, are they a special size? Float needles are my biggest bug bear, but I completely stripped the last set I installed, and used Simple Green to clean everything.

The SG was a bit harsh on the pot metal that the carbs are cast from, but it cleaned all the brass bits magnificently, and the only time they leaked was when I left it on the side stand for a week with the petcock on.

I've still got to drill the jets even bigger as it's still running too lean, but unlike the other set of carbs I had on it, at least the carbs aren't dribbling fuel everywhere..........

I actually own an ultrasonic cleaner so this is the perfect time to try it out on carbs. I bought simple green purple cleaner, I'm told it's easier on our carbs than the green, these things need a good outside cleaning anyway. The engine had a tweaked rocker cover that let some oil seep out and blow back. I sanded it on glass and went back to the allen bolts.
The o rings are 7.8 x 1.8 mm. That comes in the harbor freight o ring kit so I have plenty. I'm told 8x2 mm works well also.

Thanks Don, I've got one of those generic O ring kits, so I'm guessing I'll have the correct size if I ever need them.

Don R · « **Reply #480 on:** March 23, 2018, 04:50:01 PM »

The carbs are apart mostly, I'll heat up the parts cleaner tomorrow. We have a winter storm advisory for tonight and the am so the shop will be a good place to be. The good news is the petcock is holding a couple gallons (with a half oz of 2 stroke oil) when off and with a fuel line looped there are no seeps both on and res.
This k4 836 sure is an ugly motor. When rebuilt, it was going on an ugly bike. Now, the engine holds the bike back. I'm considering a bit of silver paint touch-up on the cases and barbeque black on the fins. I have the carbs off it won't get any easier anytime soon.

Don: send me your address, I'll send you some 2x8mm O-rings for those tees. The stock ones on the K0 with 1 O-ring each side was 2x8, and the later ones with doubled-up O-rings are the more commonly found 1.9x7.8 (or sometimes 7.9) size. I have about 100 of the 2x8 on hand, and they will usually stop the dried-out-leaks problem.

This must be the craziest color to photograph. In some pictures it's too dark and too green. In others it looks light and blue. This is under LED light.

This color doesn't photograph well, it's more green than it appears.

Looks good Don...Larry

Don R · « **Reply #487 on:** April 12, 2018, 07:03:35 PM »

Thanks Larry. The paint that looked so dark indoors in winter really comes alive in the sun. It's got green in it now too. It still needs a set of 300's.

The PO was in town last week, too bad I didn't know. I'd have loved to have shown him and his brother how the bike looks now after all the questionable things they did to it.

I rode the 70 to a Harley bike show and didn't win. Dagnabit.
I realize now the detail on the rest of the bike is lacking. This is the agony of patina, it's OK until you do new paint then the rest sticks out like a sore thumb. The header is butt ugly with the blue chrome and loooong muffler, so the next time I feel like I can spend the bucks I'll get a set of yamiya pipes from DSS.

I wouldn't worry about it Don, folks get sucked into building showbikes then don't ride them because they worry about stone chips or oil leaks marring their over-restored trailer queens, I'd rather see a well patina'd bike out on the road than a statue of a bike at a show.

Gotta agree with that TB.....LBB

Don R · « **Reply #493 on:** April 24, 2018, 09:48:54 PM »

It's mostly the $40 exhaust and engine detail lacking on it. The frame was powder coated and it's a total engine out. new wiring, etc deal so there's really no reason it isn't perfect. Except I'm easily distracted by Sandcasts, drag cars, street rods, goldwings, 400F's, and so on. All of the parts this bike deserved went on a 71 that got sold to David Silver Spares for racing money. lol.

There are parts on the diecast that have been upgraded several times. That right control probably has parts from four or five and the headlight button is up to be replaced again.

I just noticed I have soda in my ears. Off to the showers! Someday I'll build a booth until then I'll use the grey sky blasting booth. The soda keeps the grass out of the expansion joints

Don, buy yourself a sand blasting hood. Other than getting hot you won't have the abrasive or soda pelting you and you don't have to worry with that pesky soda in your ears. Just add vinegar...that would get it out right?
(Probably not if it is not bicarbonate soda.)

It cost some to restore gauges. I have a complete K2 set shipping my way right now, hopefully no beginning of cracks. It need some new parts, bottom covers, faces, glasses, seals, fasteners ... Yamiya has it all.

The old gauge setup is a vital part of the specific bikes design.
Important to be aware of how the gauge is designed to be illuminated. I have a K6 restored tacho that has very bright white light while my stock speedo has a nice green light. I noticed that the inside of top steel covers has to be painted green which must be the answer.
The older gauges might have been painted inside too...

Just drain the wallet!! An old CB750 is like a prostitute, need money all the time and difficult to resist!

PeWe,
VDO used to make bulb covers that slipped over incandescent bulbs to change their color to green, blue, red, etc.
They probably still do. You could put a green LED in the gauge.
Yes, inside and out needs to be painted and the proper color. The CB550 Tach I took apart and then shattered the face on it by someone bumping the shelving unit it was on knocking something else over that caused a cascade of things to drop among them the disassembled tach. So much for that budget refresh job I was doing. It was the first gauge I've opened...for a motorcycle. Done lots of car instrument panels and other stuff auto related. The VDO Cockpit series are not designed to be opened. Requires some careful surgery even if it has a metal gauge body (bezel not included). Then you have to replace the plastic you took away when cutting it apart... as face and rear of gauge body must be a certain distance apart. Better to just replace them. Sometimes the face and glass inside has issues with dirt or dust or ash for a heavy smoker and the bezel needs work. I've even seen the VDO that Volvo put in their 240 series with bezels that were rusting! Smoker's car and it was filthy and the gauges had a coating on the bezel and body that made them feel damp on a rainy day. That was retaining moisture and I guess the acids or dirt broke down the paint enough to make them rust. Most of the Volvo marked VDO gauges are plastic bodied for the Cockpit 52mm/2 1/16" gauges, exception was the small tach and often the clocks were metal cased/bodied.

So, see if you can find a bulb cover or go with a green LED...that would be my course of action. Presuming you don't want to disassemble the gauges. The interior paint is not a flat but a matt and it has a little texture to it giving it a softer glow.

What happens to gauges that people overcoat with a vinyl sticker? The original gauge...didn't the white/cream ink have a bit of transparency for the light allowing it to show up a little better? Not a modern lighted numbering setup...

Some of the instrument panels from 70s/80s used colored plastic film that the gauge lighting shown through giving that green illumination.

Replacement gauge faces are often too bright because the factory faces are painted on both sides but the aftermarkets often just have the sticker on one side. I notices that on my 550 where my tach has a replacement sticker on a fresh clear plastic face, whereas the speedo is still the original (it's in great shape) and I noticed when I had it apart to paint and tighten down the face screws that the backside of the face is painted green too, so all the illumination is basically from indirect light that leaks around the edges.

Don R · « **Reply #497 on:** April 26, 2018, 07:01:47 PM »

The original K0 face I removed from the tach had a light blocker over some areas of the back side. I noticed today how nice the tach turned out, it compares well to the NOS speedometer. It has 16 miles on it already, there goes the warranty. My new autometer gauges have the bulb covers but not a green, or a guy could possible try colored LED bulbs. I used a blue push in bulb in the 400F park lamp.

good stuff, Don. I've been working on bringing a 1982 KZ1000 LTD back to life that was given to me in lieu of payment for cleaning carbs. May start a thread on it $:-\$ ....Larry
