Had a previous post but thought I would start a new one. Ok, scoot is running kinda of slow, felt like belt was slipping especially at initial acceleration from stop.
Pulled the covers and looked at the var-clutch-belt stuff. First off the entire area was very clean, I was amazed. Both pulleys look almost new, no marks or scuffs or ridge build-up. I did not measure belt wear but I did observe at idle the belt would make a whup-whup sound and was moving from side to side on the front pulley. I am ordering a new belt (probably put it on at 12-14k miles, will also order a new clutch spring or possibly upgrade with a slighty stronger spring.
Re-checked the air cleaner since I had earlier noticed oil being sucked into it from the rear drive. I vacumned the air filter, removed some of the black oil from the surface. Will order a new spare but will only replace when I think the old one is done.
So, the bike was running a little smoother, also I was now rolling on the throttle deliberately from a stop. This was Ok, but my old top end speed was usually 6,000 rpm for 60 mph and 7,000 rpm for 70mph, now it was taking more rpms to reach speed. Hmmm.
I replaced the standard CR7E plug with a CR7EIX (iridium). The old plug had just a tiny speck of metal left where the ground anode was supposed to be, so much for requiring correct spark plug gap, (lol).
Now back to 6,000 rpm for 60 mpg ... etc.
