I have questions for my fellow 150S owners. I have a '23 People 150S ABS. I have Michelin City Grip 2 tires on it. I also have a iridium spark plug and have the stock 13gr rollers replaced with Dr. Pulley 11.5gr sliders. I am very happy with the increased acceleration for city driving, and have a GPS verified top end of 60mph. My main concern is my RPM's. According to the factory tach and speedometer, my scooter idles at 2000 RPM. at 30 mph is shows 6700 RPM, at my normal cruising speed of 40 mph the tach reads 7100 RPM. How do these figures compare with a completely stock 150? Can these high RPM's be attributed to the lighter sliders in my variator?

2000 rpm sounds like a high idle. Do you know what the factory idle spec is? It's usually listed on a sticker somewhere on the scoot, along with valve clearances, etc.

Stock:
Power 13.5 HP (9.9 kW) @ 8500 RPM
Torque 12.3 Nm (1.3 kgf-m or 9.1 ft.lbs) @ 7000 RPM
I changed to heavier Dr P's after I found my mid-speed (35mph) engine revs much too high for my liking.
Felt like riding around in 3rd gear of a 4 speed.....Yep, got quicker acceleration in town - but working the engine too hard for my liking.
