High Speed Variator Question
Posted: Mon Mar 29, 2010 10:42 pm
I installed a new keli high speed variator on my '85 Aero and took it for a test drive. It started to rain very hard just as I started it up, so i did not get much of a test run in. Have some questions however on the things i noticed and wondering if they're in line with is what is supposed to happen after the installation of the high speed variator.
First off, when I initially started my scooter and rode it to the top of the driveway, when I full throttled it, the scooter held steady at higher RPMs, but wasn't accelerating at more than 5MPH. I kind of quarter throttled it a little with some stop and go's, and it gradually improved to where the scooter finally took off and got to top speed. I don't know if this is just the belt breaking in with the new variator or what. I thought i smelled burning rubber, but when i stopped and smelled around the clutch cover, the smell was gone so that may not be what it was...
Second concern that I noticed right away however; is that the initial takeoff acceleration is noticeably decreased compared to how my scooter performed with the OEM variator installed. The takeoff acceleration seemed to improve the more i scooted around, but in the end it still was diminished as to before.On the other hand though, that 5mph -20 mph acceleration seems to be nicely improved along with top end speed.
So, is this the expected results of the high speed variator... some reduced initial acceleration, but an increase in low end power and top speed? If not, could this be any other issues like a loose/worn belt?
I know that the point of the high speed variator is to push up the belt on the pulley face giving you a higher gear, but if someone could also give me a more detailed explanation of the high speed variator than that would also be greatly appreciated.
Sorry for the long post...
