How much do these go for?
I grew up with 2 stroke reed motors in all our bikes!

Awwwww! Your little engine is sooooo cute!

Not sure how much benefit you get as I would think some serious port work would be needed.They sound awesome when on full song do a search at youtube for
"Marine Trevor Simpson reed motor"

Hi,
I also grew up in those reedy days. Also if you did not know Carmen Bloise from Need for speed has those two section cones on his tuned pipes pipes. As he says 70's technology with a modern twist. It really is history repeating itself.
My 2 cents worth.

Updates on racing, and the top end kit.
For the top end kit. I found you can not use the top rod bearing and thrust washers in the Zen G290 top end kit if you use the RCMK 1mm crank, because the top rod end of the crank rod is wider than a Zen crank, and the Zen piston will not fit on. You can use the RCMK bearing and washers, then the Zen piston fit on. I will double check that today.



Am finding between early and late production RCMK cranks the ROD on pin bearing end has been narrowed allowing the Zenoah washers to install without mods.

Early rods have a small end width of @ .315" and need stock washers or thinned Zens.
Newer rods are now at .300" allowing Zen washers to be used.

FYI,
