Back to this, Started porting the parmakit. I wanted to add stacked transfers like a Puch 74 Eurokit since I've had very good luck getting good speeds with those. Got the kit in my new vice and a 40 of king Cobra and got to work. Dang Nikasil is hard to cut!

I nicked the mating surface a little with my dremel chuck, sucks, I need to get some better tools.

Next is to work on the transfers from the case side and then move into exhaust width and port duration.

Started to put holes in the side of my piston but I broke a drill bit in it and cracked off the skirt cuz I’m dumb and was pretty drunk on King Cobra, so I had to order a new piston. Decided to get this DR replacement piston since the oil gulleys on the side looked like they were relatively in the right spot at BDC, and I was right!!

Got the dremel out and cut out a nice hole on both sides and it turned out pretty good! Plus this new piston has a top transfer window so I will be cutting the skirt on the kit to match

Cylinder painted and little mating surface marks filled with JB weld skim coat

BDC on Engine. I marked where the rings are to make sure they wont catch on a port

TDC. I decided to make and run a thicker base gasket to get my port timing a little better than in these pics.

Thicker gasket made with Auto parts store 1.5mm thick paper.

Engine pretty much done. Just need to finish up cleaning the clutch parts and putting them back in, then maybe I bench start it?

I remember once seeing a clip of a heavily modified motocompo in a tunnel matching pace with the car filming, and then twisting the throttle the rest of the way and ripping ahead, the glorious sound bouncing off the tunnel walls. Wish I could find it.

Finally got my shock back along with the first ever prototype aftermarket shock for Motocompo. Fits perfect! Feels great! Finally I can ride it!!

Also I have been getting into DIY milling and my first project was to try to remake a Trickmetric Dio adaptor since I needed another one anyway. Def not time or money efficient vs buying one on Treats, but that’s not the point. Here it is part way done cutting 7075 Al with a China desktop mill I modded and a super cheap $2 1/8” endmill.

Finally riding it and working on tuning. Got 34 mph out of it yesterday on the stock engine with stock cylinder Needs more tuning, I have to roll into the throttle to prevent bog and I’m running a 60 pilot.

Thinking I might just kitslap the single speed and ride it this summer then convert to the SR motor this winter when I have more time.

Look how dumb and small it is:

Hey 34 is a lot faster than it was going when it was in pieces in the garage. Really nice job so far

Re: 1981 Motocompo Build

Hope to see this if we have any rallys this year. Please let us all know which ones you will be at. I need to see this thing in person.

Re: 1981 Motocompo Build

Pritza R&D /

I’ll be at any and all Detroit and Milwaukee ones for sure. Also for sure the Creatures one in Cali in September but I’ll ride my Laguna at that.

Re: 1981 Motocompo Build

i can't wait to get totally smoked by something with 8" wheels!

Re: 1981 Motocompo Build

I need to hear this run with the new motor setup!

Re: 1981 Motocompo Build

OH MY this thing is heckin cute. That little pipe. Subbed.

Re: 1981 Motocompo Build

What are the details of the shock? Did you just piece it together from other shocks?

Re: 1981 Motocompo Build

That thing is the Pug of mopeds. So strange looking that it's cute and you can't help but fall in love with it. I'd definitely drive to a Detroit rally to see it up close.
