2001 elite sr50 max rpm????

Post by Simonsr50 »

I have an 01 elite sr50 with stock motor, exhaust and carb ; only some clutch work. I jus bought a koso mini tach and am trying to fine tune once I get my 9.8 gears in. My question is what max rpm should I be reaching on flat ground at WOT? Also going down hill?

What? I'm curious at to what the max rpm is for power on these motors? I bought the tach because I was basically spinning my tires when tuning. Because I had no clue what rpm I was running. Any info would be great.

Ok so when I am WOT On flat ground I should only be at 6500??? That seems way low for a 2 stroke motor? Anybody know for sure.

You can use this chart as a reference. This chart assumes you have a 90/90 tire and full belt travel up the drive face of the variator.

a good running stock 50cc scooter will rev to about 8000-8500 rpms on flat ground.
