I also had a bearing go bad in my +35, luckily I always listen to my motors closely and heard the bad bearing. I think there was a few engines that had a a batch of bad bearings. Nova makes greats engines, and every now and again things happen. I spoke with Jim Hottinger, great guy, and he said whenever we have problems email Novarossi, and cc him. Dont bash the company, but just state what problems you are having. He said they truly listen to their customers. I know its tough to be calm about some of the issues when these motors cost an arm, leg, kidney, etc. but hopefully working with the manufacturer will help avoid repeats of problems. These little motors are under alot of stress, and we still want them to go faster. I used to think my Novamega KHM motor was fast...and it was during its time, but the speed and pull out of the corners racers are achieving now is insane.
