Many thanks to Jim, who helped me with his expert knowledge in how to replace the drive belt on my Kinetic Magnum.
It took several tries and about 6 different guys to finally get the new belt on. But in the process, the clutch assembly came loose and the bearings fell out of sync. One of the guys took it apart and put the bearings back in place and then put the clutch back on (it is on the front of the front pulley).
With the new belt on, the 'ped starts up right away. It seems to idle just a bit high, but when I take it down from the stand and try to ride, I turn the throttle and it will not accelerate right away. Then it will finally , slowly, get up to speed...at about 20mph, it runs fine and I even got it up to 35mph (which is 5 mph faster than before I changed the belt!)...but then if I come to a complete stop, then accelerate, it just has no get up and go. It's running almost opposite of the way it was before...I used to be able to get good acceleration but 30mph top speed, now I get hardly any acceleration and more top end.
also--
The guy who fixed the clutch got all sorts of grease on his hands, and then he wiped them and put the belt back on and sprayed some carb cleaner around the pulleys and belt areas. He thinks he may have gotten some grease on the belt and/or pulley. Could this have any thing to do with the acceleration problem?
Any thoughts on this would be greatly appreciated!!
Thanks!
