Correct Cliff...the KO had the silver type cap on the front resevoir. Below is a pic of mine and I also left it as it came. Click the pic to enlarge...

Are you sure they were silver? All the pictures I dig up shows all black. If they were silver, perhaps I should put my old cap back on.  :-\

Thanks guys! Simpson, I've been collecting pics as well and have pics of a 11/69 and a 12/69 build that show silver caps. But then how can we be sure those are the original caps? There's not many "since new" oners left to ask advice of. Mark Maycok's book has pic of K0's with black caps. Maybe it was whatever came down the assembly line at the time. I have a fibreglass K0/K1 chainguard. Is it a replica or a short run original?
Cheers,
Cliff.

Whoa! Never heard of a fibreglass K0/K1 chainguard, just Vinyl or the later steel.
Neat info Cliff.
Thanks

Cylinders are painted, parts for the top end laid out, need 2 more gear clamps for pistons ring compressors.

Wonderful pictures Cliff. Keep them coming please.
I thought I was organized with my hardware laying them out on the counter.
You take it up two notches, cleaning and labeling them. Impressive
I like the cut of your jib.

Be interested hearing what parts you are updating, and where you got them if you don't mind disclosing that information.  :D

Simpson, I can't take credit for the labelling of these parts as they came that way when I bought the sandcast motor in the pictures. I really have the thank the po because he took great care in the way he took the motor apart. When I first saw the motor it was under a blue poly tarp in his backyard so I had big doubts about it all. I did organize them in the plastic tackle box. I have about 1/2 dozen of these boxes for various parts of the bike and motor.
I will have replaced the primary chains and tensioner, cam chain and tensioner, pistons and rings to .25 over, wrist pins and clips, all new gaskets, o rings and seals, replated all the bolts and washers for the outside of the engine, many new screws for the cases, replaced the finned oil filter cover with a smooth one, polished the engine covers and repainted the engine with Duplicolor 1615. I've sourced my local Honda dealer and ebay for most of the parts. There are some parts that may be a bit questionable but are unobtainable so I'll go with them. This motor will not see tons of miles and will end up as part of my estate for the boys to fight over. With this in mind I think I have a bit of latitude in the rebuild.
I will accept your compilments regarding organizing things though because I've been careful to do that- thanks. The tackle boxes, plastic tubs/containers and zip lock bags have helped me keep stuff in place. Now if I had a better inventory control system I wouldn't  have 2 or 3 of some items!

Cliff, great organisation and you have inspired me to try the same. Thanks for sharing with us your method! I know its not hard but sometimes it just takes some like you to show the way ;-). Great photos and really enjoying your attention to detail.

Good luck
Andy

I took your guys advice and helicoiled the questionable hole, it torqued down to what we needed and am happily on my way to more building. I need to polish the valve cover before I can put the motor in the frame - soon!
My buddy Rick sweating out the helicoil work. He was a bit nervous working on sandcast 1000260. A break at Tim Horton"s fixed him up.

Nice job, sleep better at nights knowing you didn't take short cuts. Yeah, I would be sweating the helicoil on a three digit sandcast also! Looking great, throughly enjoying this thread.

Now that most of the engine is done I can turn my attention to the engine cases - and they are rough. Someone tried their hand at polishing and made a mess. I have spare covers but the very early ones are much thinner and different. The valve cover OHC 750 is in much finer print and the inside seems different too. It was a #$%* getting the tappet covers off and 4 of them are toast. Why do people do them up so tight?The little cover that goes on the valve cover was painted and the hole for the front screw is lower. The dyno cover is much thinner especially at the little 1/2 moon on the front edge. This one has road rash and a small crack on the inside. I'm hoping the polishers can dress it up and some Seal All on the inside will keep the it clean. The shifter cover is especially rough. But, I want to keep all the period covers so these will be used once they are polished. I need the valve cover done so I can put the motor in the frame.

Very nice progress Cliff. Those covers should clean up nice. That tranny cover is not bad compared to many I have seen. That gouge in the bottom of the stator cover is probably more than the polisher can fix, unless you have him fill it with something. Keep up the nice work...

Thanks guys! The gouge may be a good talking point when the crowd gathers around it. People seem to gravitate towards these old cammers and love talking about them. Happens everytime time I park the K1.
Cheers,
Cliff.

I know what you mean. people used to talk solely about my "uncomfortable looking seat" when the bike clearly has more talking points.

Dropped the engine covers off to the polisher. He says he can dress up the road rash on the dyno cover too. $180, seems a good deal. Now to wait the 2 weeks patiently but lots of other stuff to do.

I didn't realize the early K was so different. Thanks for posting up the pictures of the covers. I knew the clutch cover only has 9 screws but was unaware of all the other little details. The 180 dollars is a fair price considering how much you would pay for replacments, if you could even find them. Plenty other areas to work on in the mean time!  :D
