Thanks for the info-Olbull, I have about 85miles on it now, ridin about 50-60 most of the time to/from town. I also like synthetic oil(s) for engine and rear axle unit. It is starting to get smoother all the time. The variator had a vibration or harmonic that would come in/out at lower speeds-getting better already. Just for my own information I put(3) small marks on the throttle grip at zero,1/2,and ,WOT, and an indicator mark on the stationary housing. this way I can look to see the position of throttle at whatever speed I am going (an old trick I use to use when fixing Jetting woes), any way it seems like about 1/4 throttle at 50 mph on flat surface road. I might hook up a Fluke meter to find out RPM-just to know whats what. I should have bought one of these years ago. It is so quite,and seems to run effortless on the road-I am inpressed for a 250cc engine.
