Topic: CB750 K0-1

[Don R]

 I dug through two totes of old wiring but I'm glad I had it because there was a good early battery positive cable. The battery box is mounted, tool tray, wiring harness loosely in place, pos. and neg. cables located, ign. switch and bracket, coils and wires.  etc.

 The top pic is my old K1, shoulda kept it.

[Don R]

 Doing a little wiring today, I ran across my battery cable building tools and had some red cable left. #6 fine strand. I decided to use the nice stock one though, I'll make a new one for the Rat Race though.

[Don R]

 The Rat Race bike donated a grab handle, it has no center stand anyway and it didn't make sense to have the extra weight on a race themed bike.
  What's you guy's thought on correct vin number on the motor. This one was junk except the cases, I really don't want to build an engine. A Honda collector visited a couple months ago and said a correct engine case is only worth a couple hundred difference. He's also a professional appraiser. I have a complete K3 motor under the shelves that could slide right in. Then the K0 carbs, air box and Busso pipes.

 Where do all of the taillight wires disappear to? I dug through a full tote of old wiring to find a set of correct color wiring to make up a set of harness to taillight wires. Those barn- find, rusted out and cut up bikes do have some value to add to another project.

last spring I fixed up a K3 that had broken cases, seized cylinder, broken spark plug stuck in the head, god only knows what else...so I had a K6 engine that was good to go and popped it in there so I could sell it.  Lots of potential buyers acted like the K6 engine was a big downer on value, but really they were just trying to lowball and when I came down on price the fools stlll flaked.  And these were the same face book posers that wouldn't know the differences except that I put that it was a wrong year engine right in the ad.  So just let the busters try and figure that stuff out for themselves.  Otherwise they just miss out on a really solid deal.

[Don R]

 That was my thought. For the discerning buyer I'd toss in the original cases.

[seanbarney41]

Yup, I offered the original engine...and surprise surprise no one wanted it.  In fact, I just got around to salvaging all the good parts last week.  When I finally got the cases split, the archetypical huge chunk of jb weld fell off revealing a massive hole by the countershaft sprocket in both case halves.  These K3 cases are going to the scrapper.  I feel like correct K0 cases are somewhat more important.

[Don R]

 I have a K2 case that has the rear three motor mounts welded back on. The repairs are very artistic and well done. I just can't imagine how that happens without destroying the rest of the engine along with it.

[MauiK3]

must have been a spectacular event to do that damage

[Don R]

 I asked the guy that I got the parts from about the welded cases, and he looked puzzled.
 The big wreck he had was a K3 and it went to the insurance company, that was my theory. He bought a lot of parts bikes over the years including 3 ATP turbo bikes. I got one complete set and parts. I was going to scrap the case but decided to check it out better, it had a full set of aftermarket cylinder and case studs. $$.

 Today I wired the back half of the K0-1, fed wire to the taillights and put the inner fender in, re-installed the chrome fender and turn signals. I also cleaned up the threads on the oil tank mounts and hung the oil tank. Handlebars are the next big part of the project.

[Don R]

 Today it got the rear wiring completed, rear pegs, peg bolts, tank emblems, the left sidecover emblem, I need a right emblem that is rider quality, right front motor mount,
right and left controls, throttle tube, grips, mirrors, front M/C.
 Things left to do, headlight bulb swap, front turn signals and headlight bucket wiring, engine re-assembly, chain.

 Thinks I haven't found, right sidecover emblem, carb rubbers both sides of the carbs, airbox hardware, I've decided to use the original cases rebuilt with a set of really nice, low mile K5 pistons and cylinders, maybe the K5 head also.

[newday777]

Which side cover emblem color Don? Black?

[Don R]

 Good question, the left one is gold though. I think I'll get a set from Vintage CB750, they are a lot cheaper than Z1 and Yamiya doesn't have any.
 It looks like a $400 order but all stuff I need for this bike.

[newday777]

Oh well, I have a black badge, though I'm not sure which side it is as I haven't had eyes on it in a year or two.

[Don R]

 Order in, we'll see how good the K0 carb rubbers are and if the stock clamps work. I have a big collection of stock clamps. hopefully I can make a set that work.
 I was going through totes yesterday, I think there are 6 battery boxes. Sheesh.

I have 2 near-sandcast side covers, gold (not in great shape) with the logos. Mine are black. You can have them if you need them?

[Don R]

 That would match the gold headlight bucket. A more than generous offer, I'd be happy to pay shipping and make a donation. 

[Don R]

 I combined two headlight assemblies to make one nice one. Each one had bad parts so it was good to mix and match.  I'd really like to make one that doesn't struggle to fit into the bucket. This one looks like the inside part is offset from the outer ring. I hate that, I'm going into the headlight tote to look for a better outer ring. I have a really nice one except the mice peed on the very top and ate into the chrome.

 Edit: today I dug out headlight rings and oil lines. I probably have 5 oil tanks for K and one F. I got out a nice set of hoses for the turbo motor and a good set for the K0. I hope K0 oil lines are the same as k1 and up. My shop is heavy with motor mount bolts, axles, swing arms, triple trees except K0, I have a new Yamiya triple for the rat race and two new old shop time only K1 gauges. Probably worth $1500 to 2K on ebay.

 My Vintage CB750 order arrived. I could have waited until black friday or cyber monday for 10% off dangit.
 I got two sets of points plate screws, some of them are a little chafed from non-JIS screwdrivers. I should have ordered a gasket set, it's going to be engine assembly time pretty soon.

[BenelliSEI]

If you order anything from Yamiya, add one of their gasket sets. The one I received a few months ago is excellent quality and very complete.

[Don R]

 Good to know, thanks John. 
 Today, I painted a right front motor mount with a hole in it so I can swap it to the Rat Race, that way the K0 can have a correct solid one and the RR can have one that's got the lightening hole. Details, details.
  That's one of the perks of having a bunch of totes full of old parts. The downside is maintaining any form of neatness in a shop with a junkyard in it.

 

[BenelliSEI]

Don…… those are the details that very few people will notice. Good for you!

I have at least 70' of shelving and cabinets and the shop is still stuffed with 2 MGB GT's, 8 bikes, a quad, lift table, various tools and tool boxes. It's easier to fill up 1400sqft than you think.

[Don R]

   I hear that Kelly, my theory is, unless you show strong restraint, the stuff expands to fill all of the available space.
 That 3/8" drive Milwaukee impact has 1-4 settings for power, 1 was not enough but 3 will twist the threads right out between an old Honda motor mount bolt and nut. #2 for the win and found a matching nut and bolt.

[BenelliSEI]

Don….. this year I sold a my cb750K6, 7, and 8. These bikes were totally restored and not being used. Recently I went through my spares and sorted out all the stuff I have more than two of and stuff that fits only K7/8. Filled two large cartons. All used, scruffy stuff. Common sense would say “recycle it”. I put it all back…..
