Default A Couple of Finished pics

     




I'm pretty happy with the way things have turned out. I've been doing a lot of short test rides in my town and everything has been working good. Even picking up the speed a lot is turning out OK. I'm thinking if I can get air and not break welds, this thing may hold up. Not having suspension does take a little getting used to and the impacts tell me slow down. This is test time though so I'll push it in the name of science. There's a lot of DIY fabrication work and since I'm not very experienced, I'll use "trial by fire" to make sure it will hold up.
I know there are some small things to do, like a carb kit, some re-jetting, set the timing with a light, etc., but the build stuff seems to be right.
So far.....

I need to give a little credit to a couple people who made this project a lot easier.
First, Bob Gallagher who runs the "Rokon World" forum. ROKON TRAIL-BREAKER MOTORCYCLES
When I first started looking at it I was a little disappointed. Compared to ATM the board was crude. Bob has a great line on the main page and it is perfect:

Trail-Breakers are primitive, so is the message board.
Consider it part of the charm.

Next is Dave Fillman. He has a machine shop back east and a passion for these odd bikes. Put the two things together, throw in some CNC equipment and you get:Dave's site
I don't know when he sleeps unless he has his wife running the machines. Somehow he manages to answer everybody's questions on the Rokon board too.
Thanx guys.

I might take you up on borrowing the light. I have a daughter in Orangeless County and an office in Los Alamitos so I do get down your way from time to time.

Default rokon universal joint front wheel drive

How are the front universal joints installed? and how do they attach to the miter box shafts?

Looks like the new universal joints don't disengage during a turn, is that correct?

thanks in advance for the guidance

The .75" shaft has a .25 key that fits in a slot in the u-joint assembly.
The slippage between front and rear wheels happens at the spring-wrap clutch under the seat. It works like a Chinese finger trap. I have a pic of the old and new ones back a few pages.
