Dunno if its a robin or not but its a good price and shaft is right size. http://www.surpluscenter.com/item.asp?item=28-1623&catname=engines

I believe that is Lifan 97cc engine. If you can, it would be cheaper to buy a 99cc predator from Harbor Freight.

In the product description it says RS, thought maybe it meant robin. Isn't the 99cc predator more hp than 2.5?

HyPro is the company that sells the PowerPro engine: http://www.hypropumps.com/en-us/Products/PowerPro/
The RS is the model. Could mean Ralley Sport - I don't know.
The Robin Subaru is a 2.4hp engine and doesn't look like the PowerPro engine: http://www.staton-inc.com/store/pro...el_EH090D45020_86_cc_1_90_2_40_hp-254-11.html

Yes, the Predator is a 3hp engine.

Good Luck,

I can see it for a race bike used on a closed track maybe, but for legal riding on the street, since a large majority of states have 50cc or under regulations, widespread use would scoff at many existing laws.

Actually, something like this or any of the HF engines IMO are far too large and heavy to be classified as suitable for a true motor assisted bicycle.

Mounted in-frame, they end up too wide and by default end any effective use of the pedals. Factoring the engine weight plus oil and fuel, not to mention whatever the gear reduction and final drive train weigh, begins to move beyond the idea of a helper motor and more into the realm of scooter or small motorcycle.
