You've already changed the motor oil? Because the oil that comes with the bike is a rust preventative oil, not a lubricating oil as such. If you are operating on the (true) theory that any oil is better than no oil, well, it does lubricate. Rotella is easy to find (Walmart, amongst others), and it contains zinc salts, which lubricate cams and followers better and prevent pre-mature wear. Most of these engines come with the valves too tight, yours might be the exception. Set the valve clearances at .003 inches intake, and .004 exhaust. If the valves are so loose that the engine is very noisy, re-set them immediatly. Too loose so as to be really noisy will cause cam wear from the impact load of too loose valve gear...ARH
