pocket bike motor will it work ????

i looked there but here is the thing i can get a motor thats 50cc that produces 12hp and like 10 thousand rpm i am sure thats just a bit more powerful that of the average morini motor
 
i am just wondering if a BMX frame would take it not crappy co like mongoose not gt when they where good like 2 and a half inch dia mane backbone tube about a cm or so thick not sure
 
QUOTE=racing fan;282338]i have seen motors for pocket bike both air and water cooled the[re more expensive but there high reving and can produce 7-12 hp now what i am wondering is this too much power for the bike or a bike and would you be able to fast enough to cool a water cooled engine that much?

has any one ever tried this?

Water Cooled Pocket Bike Motors[/QUOTE]

The majority of engines being used on bicycles have 76mm clutches and a specific four-bolt bell housing pattern. Looking closely at the engines on that website, I notice that these engines do not have that housing pattern.

I would not use any engine without the industry-standard four-bolt pattern. The reason for this is that you need to engineer your drivetrain and sprockets to be around 18.75:1. With a 10-tooth engine sprocket and a 60-tooth rear sprocket, you only get 6:1 final drive.

You need to be able to bolt on an 18.75:1 Staton chain drive box


or a 5:1 pocket bike gear box.

Look elsewhere for a powerful engine. You could try here:
