Turning 75 in April so decided to do one more smallframe project.
Found a solid complete frame in St Louis at a great price an that started it all.
Over the last 6 months I had Gickspeed build the motor. That took on a life of its own. New SIP. rotary intake cases. All new everything. Gears, bearings clutch. Pinasco crank, Zuera 145 top end and flytech. 24 carb and ceramic coated PM Tuning Evolution pipe.
After the little bodywork issues are sorted will have a local graffiti/street artist paint it.
It will ultimately go to my younger son along with the 64 so any value for money considerations don’t really come into consideration.
This is one time when being old works to my advantage.
I’ll do occasional updates as it progresses.
Here are some pics to begin with.

Looks like a fun time and a sweet build.
I plan to follow along and learn all I can, and then maybe jump in with both feet and do a build myself.

Decided on a base color for the graffiti. Gallio Cromo 933. Only having graffiti on fender, front of leggy and rear section. Chassis is down at Gickspeed having the holes welded up some body work and a clean title. Will have it shot with color when it comes back.

Found just the right seat for her. From SIP it’s a really nice product at an outstanding price. Set it on the 64 to check fit. Particularly like that it doesn’t overhang the rear and sits high enough to show all of the chassis detail.

I just noticed that the SIP cases still have the oil galley that goes to the fly side crank bearing in the same location as all the pre-PK engines. I wonder how the oiling efficiency compairs to the PK oil galley?

I left all of the component matching to Jonathan at Gickspeed since I just know enough about these motors to be dangerous. Over the years that I was working as an account manager in the tech world I realized that I only needed to know that a solution would work and that there were people on the team with in-depth knowledge of how it worked. That has become a life long approach. Bottom line is I only take on the things I know are within my capabilities.

Back from media blasting. All holes being welded up. No badging, using early style taillight with painted housing. Then off to panel beater and for paint.
Front end back together. Crazy Monkey anti dive. SIP shock. Just waiting on Newfren brake shoes.

Looks nice with the hole filled, whats the final plan for paint colour? And yes antidive is a must as when we drive a smallie even a twitch touch to front brake lever and the front get dive like a submarine even with a standar brake shoes.. Thats or a stiffer spring

Good luck with the paint and cheer

Having serious second thoughts on graffiti paint. Chassis is going out to Gickspeed’s paint and body man. Here is an example of his work on a Rally 180.
Hadn’t initially planned on this level of finish. There will be some old school hand lettered signage on the left side door.

Can’t paint over this kind of work.
Can’t wait to see my chassis in Gaillo Cromo 933

Nice paint there!

I can see why you woudn't want to ruin it. But please get a little adventurous with that old school hand lettered signage and make it really your own. Left side door only? .

And this Gaillo Cromo 933, got a scooter pic or something you could share for a little preview?

Could you not use decals for the graffiti? Then if you change your mind the paint will still be sweet underneath.

Here's another option. When I wanted to add a bit of flair to my exPrimavera, I decided try flat black on the bottom portion of both doors. I picked up another engine side door from ScootNet and had at it to see how it would look. I liked it fine at the time, but would probably just stay stock today given the good original paint. So on the rare battery side door I applied a couple of coats of good paste wax, masked well and sprayed the flat black over the wax. Seems to work well and you can see here a small area where the black was scraped off.

Exmayor your scoot is going to be so cool, I have a GickSpeed motor as well he did up for me back in 2012, I’m getting close to running it for the first time. Does that huge flat piston change the compression ratio at all?

I’ll have to check with Jonathan to see what the compression ratio is. I do know that when I had both motors in the engine stands it took about twice the effort to push the 145 thru by hand as it does to do the same on the just broken in 100Sport motor in the ‘64

Exmayor - great project! I'd be very interested to know what jetting you have in the PHBH? I have a Zuera 144 that has not been run yet except for about 20 seconds when it was first built.

My PHBL24 is jetted as follows
1. Boiler (jet drum). 40
2. Needle D22 clip in center
3. Main. 100
4. Needle jet. AQ265
5. Idle jet. 64
6. Choke jet. 60
Air correction screw out 2 turns.
My motor is rotary intake not reed valve
Exhaust is PMTuning Evolution
The jetting is what Gickspeed received from his Pinasco rep. Ran perfectly on test stand.
I may not have it in the chassis until over winter here is Wisconsin.
Have had a couple of medical setbacks that have kept me from riding and need to do the last few things to get the 64 back on the road.
Hope this helps.

They are beyond being reasonably prices but I started using tapered bearings 25 years ago when I rebuilt the ‘66 Triumph 500. Changed them out on my Monster and used them in the little Honda 100. Those all came from all balls and were relatively reasonable.
Have a set installed on the ‘64 V90 and they are glass smooth.
Since this build has stretched over time and will go thru winter, costs are now being totally ignored. It will go to my younger son along with the ‘64 when I can no longer ride. Hopefully will be a while.

That is one good looking front end, nice idea for the bracket for vise as well.
When I started running my bike with the new front end I was getting alot of bouncing from the brake pads wearing to the new drum, much better all ready. At first I thought I had a loose bearing but quickly realized it was just the front damper and spring action.
