going for a different look, on the Comic flyer.after LOTS of clean-up.

gonna put in LED lights, mod the muffler and build a custom intake manifold.
Have already moved the transfer ports, and milled the jug. Anyone turned the jug 180*

Yes there is one. There is not too much of an advantage to one for us. On some of the early racing bikes they used them, but I think they were rotary valve engines. I like the bike you have chosen, Very cool. Have fun, Dave
 
Davo you are using the Russian engine, how do you like it? Looks cool in that frame. There are a few company's that are starting to make some of the older style bikes again, I love all the space age looks from the 50's. Beautiful bike. Have fun, Dave

PS: That engine is a rotary valve engine using a small hole in the crankshaft as the valve. The German MZ was the first to use a flat disc rotary valve. It gave an infinite configuration for tuning, stolen by Suzuki racing as the MZ rider came to Suzuk. Then Yamaha. A lot of the model engines use the crank rotary valve, known as glow engines.
 
Found out what the secret was, says lost 684g. off the crank:geek: Howard and Allen say this engine will run real smooth. They just got back from the balance shop.:cool:
They say lost weight at the crank, is a good thing

I'll be the first to ask. What's up with the bar sticking out on both ends? And flipping the jug? Can you do so without any other mods?

I had to go ask. They said the bar is part of a "jig" that holds the engine, horizonal to the crank center line, used to true up the case to jug surface, and to mill the case to lower the jug. cause Allen says the intake is to high.also said "looks like they plunge cut the surface" at the factory.. this pic you can see the low places after just a slight cut

flipped the jug, just to be different:geek:

I believe that bar is just taking up space, until they put that balanced crank back in there.

y'all are taking these engines a whole new direction.... kudos!!
