So, I've owned my first RC for almost a year now. One of the first things I learned was how on/off the bike is at slower speeds just as you crack open the throttle. Bike is always "chomping at the bit" as someone else put it. What has been bothering me however is the large amount of slack in the driveline, which is really adding to the herky jerky-ness of slow speed riding. What I mean is this: when I have the bike on a rear stand and in gear, I can move the rear tire forward and backward a couple inches before it stops. There seems to be alot of play somewhere, and it seems like its within the transmission. The cush drive seems tight, the sprockets aren't excessively worn, the chain is brand new. When I'm riding and I go from deceleration to acceleration, the bike jerks forward a little due to the free play. Is this normal? Should I be concerned? What steps can I take to minimize this issue?
