Just a newbie question. Installed a Boygofast kit on an Onyx 29 inch bike. Everything is assembled with the exception of the throttle grip and clutch lever since they won't fit my handlebars. So my question is shouldn't the rear wheel spin freely when the clutch is arm engaged? When I position the clutch in the idle position I'm still fighting engine compression. I pulled the cover when installing the chain, could have fouled something when i reinstalled the cover and arm?
