Howdy everyone! My father-in-law was Farmdog on here. He passed away back in January with about 7 bikes he was in the middle of working on. I haven't done a full inventory on his mini's but it looks like about 4-5 early 70's Z50s and 3 CT70s from early 70's as well. We have one of his running Z50s in our garage, that my wife grew up riding and he has 2 other completed Z's in his garage. These are new bikes to me as my past have been working on late 60s/early 70s Triumph unit bikes and my '02 Harley Dyna. It's been almost 9 years since doing any engine work as kids and a growing family took over my time. I'm pretty close to being done reorganizing my work space and bench to start working on the Z50's as winter approaches here in Colorado. The only thing I do regret, after Farmdog passed, was not asking him to work on his restoration projects when he was commissioned for them. I'm sure I'll be reaching out as I start getting into the first bike I crack into. If all goes well, I'd like to be able to pass on the family legacy as this was something Farmdog always had fun doing. I look forward to getting to it and sharing what I can as I'm going along.

Thank you both! Davmo, I'll definitely get pictures up and list out the models once I know what the inventory is. I'm excited and nervous at the same time. I have big shoes to fill when it comes to taking over these builds.

Here's the last engine that Farmdog was working on before he passed. I have it setup on the workbench and got the oil pump and gasket installed. Took time over the weekend to clean a used Type II manual clutch assembly that I'm almost certain was what he was going to install in this build. It was the only clutch assembly that he had with the parts on table when we boxed it all up. Now I have to go back to his garage and look for the remaining items he might have been planning to use on this. Need to find the primary gear circlip to keep moving forward. Here's some pics so far of what I've started with when I got everything back to my workbench.

Looks like it has a TB Parts 88cc big bore kit and race head on it, so you have a good base to start from. you can use this diagram as a guide to putting the manual clutch together. The concave (or convex) thrust washer in the pic above should say outside on it, and facing you when you put it on, under the locking tab and special 4-point nut.

Thank you for the info. I do have the parts box for the head you described. I really didn't know he was putting this one together as he never mentioned it when we would go over their house. Thank you for the diagram link. It matches the same one I was using in the Clymer manual that I grabbed from his bench. Wasn't certain if this was the actual clutch intended but it sounds like it is from your knowledge. Question... this is still technically a 3 speed auto, even though the book calls it a manual clutch? Why do they call it a manual clutch in the book? And Thank you for the heads up about that washer. I was going to ask about that. As for the lock washer, does it matter that only 1 tooth lines up with the clutch nut? A lot of videos I've seen there's usually 2 teeth that line up. On my Triumph 500 build, all teeth line up so it kind of confused me for a second. Thanks again!

The diagram is for the Honda manual clutch used on a CT70H, just to show you how it goes together. The 6-digit Engine VIN is indicative of a '69-'70 Z50AK1 hardtail, which originally was a 3-down semi-auto trans/clutch setup. Is the manual clutch a new TB Parts kit, do you know? Everything you need to convert to a manual clutch on the engine is shown HERE in a TB Parts kit

That's correct, the lock washer uses only 1 tooth bent over to hold the clutch nut in place.

Also, the little part to the right of the lock washer in your pic above goes into the throwout bearing in the cover to the left in the pic, and the small part with the spring then goes into the center hole of that part, spring end first. Those parts are referred to as the oil through and are not shown in the diagram.

I'm not actually certain if the clutch is a TB Parts kit. When I got everything over to my place, the clutch assembly was loose and had dried oil residue and dust all over it; definitively a used part purchase and no box for me know exactly. I took the whole thing apart and got the innards all cleaned out, degreased and inspected the plates; which all look really good still. That funny looking blob on the cover is some kind of discoloration. It's smooth and won't even come off with a soft wire brush. I was even looking for any markings to note who made it but didn't see anything that was obvious.

There MIGHT be a 4speed transmission in there..? Maybe show us a picture of the right side of the engine.
He MIGHT have put a stroker crankshaft in there too..? Maybe look for a box that a crank came out of.

When I get through with work and get over to the bench, I'll snap a pic for you of both sides. I'll check the shelf in his garage for a box. I don't recall seeing anything that big on the shelf when I was initially going through the shelves to organize parts and such. As for notching the case, I really am not certain if he did that or if he got it that way from the seller. Farmdog knew a lot about these and I usually never got in his way while he was working on them; I didn't want to seem like an annoying son-in-law "what's that? what's this? what's that do? is that the thing that does the thing?" haha. I do know that every engine he picked up, he got them for a sweet deal. He could very well have seen this one, knew exactly what was done to it and bought it because it was suped up a tad, but I'm not entirely certain.

I had to read this a few times to fully understand it. Just so I'm understanding correctly, and read the link on the manual conversion kit link you supplied, because of the big bore race head and 88cc conversion on this, the clutch assembly in the photo is what's needed? Does this mean I would have to purchase this kit or look for it in his parts shelves? I wasn't sure if a manual conversion is required for this clutch or not. Thank you!

Yes, that's the reason I posted the complete kit picture, so you know what to look for. That way you can determine if all the parts are there, and be able to use the manual clutch.

The manual clutch isn't required with the big bore kit and race head, but a heavy-duty semi-auto clutch is recommended for it, over a stock one.

Awesome. Thank you for confirming. Sorry about any of my confusion or anything. These bikes are so new to me and not having any idea of where my father-in-law was going with this one has made it challenging and I appreciate your patience and information. I can't thank you, and everyone else, enough for the help so far.
