Ya man, post about how it works out. Also, is it possible to explain how the transfer ports in these engines work? I really dont get it. I was always under the impression that in a two stroke, the intake air/fuel/oil mixture went strait into the crankcase, not into the cylinder then into the crank case... Hows that work?

I heard you bought it from David Rust when you bought your Reed block . Some body fibbing . you can't do it with the drum sander ,like the one of your YouTube video .

Yes it is possible with the right bits the one in the vid I did myself and works great took me about an hour to do and yes I do buy from rust. I also took .50 off the top which rust does not. Which I had my local machine shop Do that part.

Why is that interesting?
You bought one of the reed ported cylinders from Arrow Motorized Cycles
and sort of copied Daves work.

All the changes you made to your cylinder on the video degraded the performance.

If you think your mods are better than Arrow's bring it out to the next
SoCal Motor Bicycle Racing event on June 1st and take all that purse
money! :D
