Puma Romeo 150cc Slow off the line?  By  spencer (Read 2,720 times)

Hi guys, I have a 2013 Puma Romeo 150cc scooter that has about 1,100 miles on it currently and has been well maintained. I have a NCY drive face, 10 g Dr.Pulley Sliders, and a Gates kevlar belt which was all installed about 200 miles or so ago. My problem is that off the line the rpms kind of dip for just a second until about 10-15 mph and then it shoots off. Now the acceleration isn't horrible off the line, it's just not as good as it was originally. When I first put the sliders,belt, and drive face on the acceleration was great for about 50 miles or so and then after that it went back to that slow take off which started after about 400 miles of riding when it had all stock parts. I am thinking it has something to do with the clutch torque spring being worn out from all the stop and go traffic I ride in plus my aggressive riding.The variator and everything is installed correctly and yes the carb is spotless, valves are good, oil is clean, tire pressure, etc. Any thoughts on what this might be?
