**SR.MAILMAN** · 08-20-2011, 02:10 PM

I wanted to start this thread to see if their was any interest in a 70mm piston upgrade, to make a TRUE 250cc engine.

Hopefully this link will have them in October this year.

Did you get a response from that site? I'm interested.
Here is the one that I've been trying to get but it appears to be vapor ware. CG400?

Someone could sell a bunch of these engines if they exist to the DF250RTB, DF250RTC, Heist,etc owners.

The web site mentions October, as a target date. I think he is putting out "feelers" to see what the interest might be...

Yeah, that is the reply that I got. Nothing else when I emailed them.

hmmm wouldnt this tech work with the CCW bikes since they basicaly have the same motor...

Should work since they are both 167FMM (CG250) engines. However the gain is only 21cc or so. Doubt it will make a big difference in performance.
We need a 400-500cc easy to swap engine.
