Title: Looking for V2 Magnum plans by Steven Pierce
Post by: V 45 on June 03, 2012, 08:03:27 AM

I found this engine while doing some surfing..actually found an email but came back undeliverable. I would like to try and make this...Steven Pierce's  60° V-twin motorcycle engine. This engine is run on CO2. The scale is about 1/16 and it is made from brass and aluminum. It has a 1/4" bore and 1/4" stroke and is called the "Maxum Magnum."

After looking around somemore ... it was brought to my attention that it's based offf this engine build by David Kerzel.

But I still don't see how he mounted the top of the engine in the Magnum version? Any suggestions ?

Are you talking about the "valve covers"?

It might be possible the are screw on. I just saw a radial build (gas) where the designer did that.

Hope that helps?

I have DL'd the Dave Kerzel plans awhile ago and it is on the list!
