Great. The last piece of the puzzle! If it fits PM me with a price! Thanks!

Putting the engine together. I was able to locate a good cylinder that fit a set of pistons from one of the bad motors. I'm looking for a standard size set of rings. I have 1.0 and .5 overs, but no standards.

Does anyone have a standard set?

I can't help with the rings but could you explain why you want to put an internal throtle on your bike. What years had internal and which had the external? Does one work better than the other?

The bike will be a 1965. Both frame and engine. My previous CA95 (1965) and
CA160 (1968) had internal throttles. So I am trying to keep the final product as close as possible to what was available that year.

As far as what works better, internal or external...well I don't really know. I also don't know what years had the internal or external throttle set ups.

I am working on machining a slot into a blank set of new bars and retro fit an internal. I also have a set of original set that I'm refinishing the steel for plating.

My 64 has an external but since it had already been partially restored I have no way of knowing if it came that way. I like the cleaner look of the internal so I may look into changing it over if I can come up with the parts.

Just some pics of motors in progress for the CA95 build. The far right engine is for this build. The one on the left is for the CA95 build after this. A thread will be started for the 3rd build later this fall.

The build from scratch engine is finally coming together.

Soon it will be ready to install. The wheels are being taken apart and polished. I found some nice wheels with good rims and they are soaking in my phos bath. Once the spokes and hug are polished they will be relaced and trued. I am waiting for my run out guage for my truing stand.

Spokes ,Lookin good . I'm sure you've thought of this but just in case , after you've rebuilt the head it's much easier to set valve to rocker clearance by adjusting the valves with the feeler gauge going thru the upper motor mount opening . You don't have to fumble with feeler gauge , 10 mm wrench and rocker arm wrench ,plus you can see the rocker on the heel of the cam .

Now that is a great suggestion! I will set the tappets exactly as you indicate. I have to mention another suggestion by Sam Green. When installing the piston & rings, 1st set the inside circle clip into each piston. With the cylinder off and upside down, install the pistons so the rings are in the cylinder up to the piston pin holes. Lower the cylinder on the studs and align the the rods to the pin holes, slide in the pins, set the circle clips...and your done!

I used a stop to keep the cylinder at the right height while inserting the pins and clips.

Thanks again!

I ended up with 2 NOS upper guards

If I come across one on ebay or elsewhere, I'll let you know.

Thanks! A lower guard will show up somewhere I'm sure!

It is hard to believe that 1.5 years have gone by since I started this thread. Sometime in the next two months the bike will be finished. I am also finishing up the 66 CA160 along with this build.

Below is the latest pic of the engine build. It is close to being finished. This engine has been assembled from many parts of other motors.

Time sure flies. It just takes a so much time to gather parts for these projects. The little Honda 150 looks great! Always nice to take some pictures of the engine assembled before it goes back into the ol' bike. They are just good looking engines.

Today new tires, rim strips and inner tubes have been ordered. This weekend (weather permitting) the final body work will be complete and 1st color will be applied to all parts less the lower chain guard...still looking.

Final color will be candy apple metallic red. The only decision is to go with grey undercoat or black undercoat. I'm leaning towards the black to give the bike that dark cherry look.

Pics next week

Good luck firing it up and popping it out of neutral for the first time
