yeah i had that problem when i got my 750....thought that it was not possible to go 180 mph but thats what it said on the clocks....thats when i was told that i was probably doing about 165mph but becauase i had a smaller rear sprocket it was giving the sensor a false reading........in fact if anybody here knows of a way i can change the sensor or an add on i can get to make the reading correct again (cos i still have this problem)....
many thanks. and good luck
