if you make it too light when you roll to a stop the engine slows you down very fast, like an engine brake
I was afraid of this and had even bought another flywheel just incase that happened. It didnt.
He also did my zuma 125 flywheel too and again no engine braking which is great. I like how far I can coast to a stop.
Now maybe because they wernt super light I didnt get the engine braking like others have in the past done by other companies.
But both my flywheels I did not feel any difference in performance. But since I have 2 scooters its harder to tell because they are both way different from eachother so its hard to remember the feel for something if your not riding it every day. And both of the scooters I didnt ride for a couple weeks so I probably lost any feel I had over that time.
and you dont want it too light it wont run good you need some weight on them
