I have a 90cc 4-stroke auto engine,and i want to know if there is a way to reduce the engine braking on it,if it can be done please send info on how and what to do or what web site. THANKS TO ALL WHO HELP

What do you mean by engine breaking? I'm only familiar with Jake Brakes.

what i mean is when i let off the throttle the internal friction of the engines moving parts will create a bit of inertia which is then applied to the rear wheel causing the motorcycle to slow down or brake

I WANT TO KNOW IF ANYBODY can tell me how to reduce engine braking on a 90cc 147fmf automatic 4 stroke engine
