A bada$$ 25cc it is.

I've got to pat myself on the back for this one, it surprises the heck out of me.

The bike's a mongoose, steel frame. Ryobi 25cc now has cone filter, venturi intake, 10mm carb bore, hi-flow RC car can exhaust.

Direct drive with lift clutch pushes a Goped 0.930" knurled roller.

It accelerates, it climbs hills! Top speed maybe 18mph no speedo just butt dyno, its got more than half of my 48cc geez.

I ran it hard today, on a hot day, and its got so much fuel and air going thru it now it screams and doesn't get hotter than it did puking at half-throttle.

Low RPM grunt is very pleasing for a puny motor.

Gave it away. Hope brother looks twice and then again b4 that next turn!

That's a sweet bike. I need to build a simple one like that. Beautiful craftsmanship

Anyone remember this abomination? My first one, I blew that half-shaft 30cc smoking it down hills, it ate up chains for lunch.

Learned a lot.

I believe a certain member is contemplating a build like that now.
