What is the rev-limiter of the WR400 set
at. I have been told by Thumper Racing
that the WR limiter only lets it rev to
8,900rpm and the YZ rev limiter is 11,500.
Can anyone verify this and if its true, what can we do to change this. I already know that you cannot simply change ignition
boxes on the two bikes.

Someone told me the WR only revs to 6495 rpm..for longevity reasons...that would explain ALOT!
