Found this in manual and if i understand corectly it must read 0-199 in diag mode under parameter 07. On my bike it counts to 999 and after that resests.

07 Vehicle speed pulse Displays the accumulation of the vehicle speed
pulses that are generated when the tire is spun.
(0 ~ 199; resets to 0 after 199)
OK if the numbers appear on the
meter.
