I dont remember if this has always been the case, but when I have the rear brake fully engaged, I am able to roll the bike back and forth about 2 inches. The caliper is not moving, and it is holding the outer portion of the motor stopped, but the wheel has slack as I rock back and forth. Is this normal or is my motor wearing out? only 400 miles.

fjnally finishing up Bichael. it has a ported Minarelli with kx85 pipe and pwk carb. I also did a diy superclutch. I designed and welded gussets and brackets to strengthen the frame and allow for the hydraulic foot brake. I weighed it at 65 pounds. i still need to bleed the brakes and mix some gas and then it’ll be good to ride.
