RPM

Default values are for a 2000- DS650.

The stock RPM range is up to 7,700 RPM before the rev limiter cuts in.

with a new cdi runs show 8500 as being the max working RPM, unless engine work is carried out to obtain more revs.

Wheel diameter can vary subject to tire choice. Measure roll circ and use C=Pi times D to calculate, where Pi is 22/7
