I Just replaced the Vbelt and sliders on my 2003 I purchased 2 years ago, 4,200 miles on it at the time. I didn't want to chance the old belt failing from age. New belt OEM.
The old belt looked fine, so I'll keep it as a backup though I'll likely just replace it with a new belt in 16,000.
I used 26 gram tech pulley roller/sliders.
First impressions, The takeoff is much smoother with less lag, and the biggest gripe I had with the stock rollers was that at lower speeds if you quickly back off the throttle, the compression braking was almost like hitting the actual brakes and it would throw you forward. Very annoying. The new sliders really minimized that issue.
They have turned a scooter that I really like into one I really love.
A question...My v-belt light wasn't on, but when you reset the v-belt light, does it reset the mileage reminder for another 16,000 miles?
