OK Guys (and Gals),

I have a GP 29% Christen Eagle II. Currently, it has a Fuji 50SB with a standard muffler in it. BUT, with that HUGE engine in the front (about 5.5 lbs!) I had to add 8oz (!!!) of weight to the tailwheel bracket just to get the CG close to the middle of the band.

I need a new engine.

Looking for a light-but-powerful 50cc gasser to stick in there. Contenders so far:

Brison 3.2
ZDZ 50NG
DA-50

I'm going to look to buying a used one. I'd like something lighter than 5.5 lbs (!!!!) so I can take the tail weight out.

Suggestions???? Help!

Thanks!
