Got it!! ThanksNo. The Allen screws end short of flush within the clamp. Only the smooth side of the clamp grips the chrome handlebar providing ground for the turn signal or any additional electrical connection.

Speedometer saga continues! So, order a new speedometer cable. The bikes last 4 serial digits on the frame is 4135 (1962). I get the new speedometer cable, the cable fits the speedometer just fine, the speedometer drive end is too small! I ordered the right part number, as so I thought. Deep dive into part numbers against serial numbers I discover the drive unit fitting at the wheel changed sizes after frame number ending in 6000. So, I've ordered a speedometer drive for a 1963 -1965 model year. Now I'm pretty sure the wheel hubs did not change from year to year, if not, I will source a pre 1962 speedometer cable, after I hide all sharp things and avoid cliffs and bridges...I greased the odometer worm gears with machine gun grease (the plant I retired from made fine bearings for military). I didn't think of any dampener though. If for some reason I need to go back to the speedometer I can open it up again.
Finally put a close to the speedo story. Face is reattached with acetone thinned 2-part epoxy and coated in silver enamel. I laser cut a thicker gasket than stock to make up any roughness of my seal job. Any excess gasket once installed and subsequently compressed will be trimmed. Here is a couple of pics of the finished speedo.

Confirmed. Earlier speedometer drive:Truth will be told when I get the later year drive.
I'm not sure of that. Logically, since the chain is traveling over and under the protector, one would think the chain would catch a gap lip and tear it off. I'll address the concern after engine mount.The black plastic chain protector on the swing arm is upside down, IIRC, the gap faces up. The chain case tins fit better.
But I have to stubbornly do it the wrong way several times first, it's in the rule book!I figured Tom knew what he was talking about, he's good like that.![]()
Pictures not showing. Measure the diameter of the valve seats, that should indicate which valve fitsTwo pics, the cylinder head. 1st pic is before (remember bent valve?) and 2nd pic after. Logic has failed me before, but it seems the valves are reversed. Then again, maybe not. I recall doing a brake job (50 years ago) on my 67 SS327 Chevy Impala. I replaced the rear brakes exactly as I found them, only to discover the PO installed them wrong. Could the valves be reversed, Larger for exhaust, smaller for intake?View attachment 38448View attachment 38449
Thanks for the suggestion! I did exactly as you suggested and happy to report no leakage. My bikes in the past have been 1964 to 1968 model years. In the past, I've sourced two engines, one for my CA95 Build from Scratch and the other for the CA95 Army bike. Both engines 1964 &1965 model years. I basically cleaned the head, lapped the valves, bored the cylinders, cleaned the internals, replaced gaskets and seals and I was good to go. This time around with this 62 has been a different experience. As mentioned in previous posts, I bought a 1963 CA95 engine with so called low mileage, but "stuck". The engine was wasted by massive internal rust and seized rod. Ok, so I get the engine back together and I need to service the head. The sourced engine head can't use. Rust grit destroyed machined surface the cam rides on. The head that came with the bike, presuming it was part of the original engine, may have sat for decades, but alas, still good, with the exception of a bent valve. The bent valve, due to an incorrect single valve spring (somebody installed the wrong valve spring) broke the valve guide. I decided to install new valve guides and valves. I was going to send out the head and have the job done. Estimate cost $350 + Shipping to and from Utah. Let's say $400.00 with shipping. That's with my parts sent with the head! Valve guides and valves-$100, so now I have $500.00 in the head alone. So, I buy the driver for the guides, remove the old ones, install new ones, buy the correct reamer, ream the guides, lap in the new valves (seats looked ok)You can at least test the head with valves and springs installed by laying on it's side and filling the intake and exhaust ports with gas or very thin liquid.
It's definitely a problem that's only getting worse. There's basically no engine rebuilding today in the mainstream shops so they never learn the actual working components and how to service them, or even really how things function. Not to sound like "get off my lawn" guy, but so many more of recent generations went to college instead of technical schools or going into the mechanical field at a local shop, the drop in general mechanical experience among the masses is way more than just attrition from the old ones dying off. And the way local shops either decline to work on vintage, or purport to be able to while often screwing up the job, things don't really look to improve.I appreciate forums like this one, I think those of us who like wrenching and understand basic mechanical terms, are a dying breed.
That's great. You hadn't really shared all the head work you did, but it's really pretty interesting to me. I haven't had bad guides yet in the ones I've done. I actually bought a real cheesy Chinese valve seat cutter kit that kind of worked to get one useable and bought some Asian replacement valves (that did look different) and was able to get it leak tight. It runs good, valve adjustments seem to be holding and it maintains good compression so if it lasts ok, I'm calling it success.Thanks for the suggestion!

The intake valve appeared different as it was dimpled rather than flat. My thoughts reverted back to the fact 1962 CA95 and earlier may have parts that differ from 1963 and later models.
Thus, my questions regarding valves for this build.
One other aspect, that makes me nuts is the lack of common knowledge at local motorcycle dealerships, like "Can you cut valve seats?" Whatsa valve seat?

Yes, but only to clean up the surface. I have a piece of flat tool steel that I use for such tasks. I hope the head is flat enough to use. We think that mechanically inclined people are hard to find, try looking for a machinist to mill a flat surface.I meant to ask, are you going to check the head mating surface by sanding on a plate glass sheet (old refrigerator shelves) also the cylinder top too?
Cool magazine! My second bike was a '69 CL450. Funny that your father hated Japanese products, but the Italian Aermacchi Sprint was OK. Italy was one of the Axis powers in WWII. I have a 1970 350SS Sprint in fairly decent condition, and very complete. I hope I get around to it before I check out. It has occurred to me before that I have bikes from most of the big powers of WWII: American, British, Japanese, German, Italian, and even Austrian. That just happened sort of by accident. I don't have a Ural, though, but they're just a poor copy of a BMW and I do have a couple of those. My dad just hated motorcycles period, regardless of who made them. I think I have overcompensated for that, becoming sort of a mcy hoarder. At least that's one excuse.One of my brothers gave me an April 1968 Cycle magazine. Attached pictures are of the new Honda line-up, two-page ad. The third is the Harley Rapido, my very 1st legal motorcycle, April 1968 was one month before turning 16. Regrets of the time was my father's hatred of Japanese anything. He was still pissed over WW2. Anyone who drove a Japanese car or motorcycle had to park it on the street. Fortunately, at the time, my "brother" Dave rode a Harley Sprint. Cheers!
His cousin was killed in Belgium by Nazis, Germany invaded Poland, and his parents were Polish immigrants, but he drove a 1964 Mercedes. My argument as stated, if voiced at the time only resulted in getting slapped.Funny that your father hated Japanese products, but the Italian Aermacchi Sprint was OK.

Oh I remember those times well. On the heels of the era of "children should be seen and not heard".My argument as stated, if voiced at the time only resulted in getting slapped.
I've been lucky in some respects for sure.Wish I had connections like that.
Well, I put in the old rectifier anyway. Today, I completed the electrical system. Installed my new battery. Turned the ignition key to "on", 15-amp fuse blew. Installed another fuse and quickly turned the ignition key past "on" to lights. Head light illuminated dim and died. I have a short. I've gone through pains to make sure connections are correct and clean. Four theories where the short may be. 1.) Old rectifier 2.) Ignition switch 3.) Alternator assembly 4.) Somewhere in the jammed packed wiring in the headlight bucket.I don't really trust in the bolt for an adequate ground, so I run an extra ground wire, with eyelet for the bolt, directly to the battery negative. After noticing signs of overheating on the 3 positive wires on those (or even outright fried unit failures) I was clued in to the fact (by others) that a good negative return was essential to a balance of current flow.
For what it's worth, I've gone with those simple units like the one you pictured for awhile but eventually now have a Sparck Moto 6volt rectifier with a voltage sensing black wire, that I tied to the rear brake light switched positive lead for a regulator function as well. I think this is now finally the extra robustness that I've sought from various bulb blowing spikes, battery overstress and such that seem to pop up sometimes on these old bikes, like my 63 Be
