Jeff, It looks like one of the typical pocket bike engines, probably 49 cc. They are high winding engines, around 10,000 RPM'S. They fly once you get them going but they don't have much power getting started. You might be able to gear it really low. That's what I used on the mini bikes I built.

looked up this engine and it's claimed to produce 4.2HP @ 11,000 RPM and is a 45.7cc engine. looks like it would take a good bit of engineering to set it up on a bike, rig one up and let us know how it works out who knows may be another set up but probably to costly for most @ $255.00 just for the engine. you can set up with the little china girl pretty darn good for $255.00, if you decide to give one a shot I wish you great success.

Been there, done that.

This $255 GP460 engine, bolted onto a $129 BMP friction drive is the most powerful combination you can ever assemble at this price. With a 1.25" friction roller, this baby screams past 40mph for less than $384. That Happy Time engine will need an SBP shift kit to run with this engine.

At this price range. no other utility-type engine can come close to its performance. Quality engines(non-Chinese) producing 1.6 hp to 2.8 hp cost more and deliver less. Staton's entry-level 1.6hp friction drive kit costs close to $400.

However, there are major problems. Here's my attempt::-||
