Just installed a new belt, air filter and replaced the original rollers with Dr Pulley Sliders. The scoot has 6600 miles on it. The old belt was well within spec as measured. The rollers were pretty beat up. A little freshening of the clutch bell and pads was needed as well. I chose to go with the same weight (13gm) as stock rollers rather than the 10% lighter normally called for.
Acceleration off the line and roll on feels the same according to my seat of the pants dyno. No disappointment there as the bike is pretty "revvy" anyway.
Top speed increased a couple of mph. Any improvement there is welcome. Aparantly, the final gearing holds the bike close to a true 60mph. at red line of 9k. As strong as this scoot runs it is surprising 65+ is not delivered.
I may try going lighter with the slider weight just to see if there is a difference.
Overall, this is my favorite scooter in the 125-150 class. Kymco hit it out of the park with the Movie.
I call it the "TFM". Tangerine Fun Machine. 😊
