El pepo sorry! I have no idea what brand this engine or kit is..

[@bilalc.2192]

Nice bike. Could you tell me your complete set up?

[@hanskarlsson525]

Bilal C. Thanks! Read the description. 36 tooth sprocket, thrust racing muffler, boost bottle and I windowed the piston to get better airflow form the intake port, also slightly raised the exhaust port.

If you are using 26"x1.75 tyres, then your engine's RPM was 8700 at 69 km/h. My max. was the same, but my RPM was only 7600.
