Does anyone know what the max revs for an R1 5jj 2000 ish aged engine is?
Need to see what revs Castle Combe will test the noise levels at ie 3/4 of max revs??
Cheers

The 4xv engine is 11750. I wasn't aware of any change up to 2004 when it went to 13750

At SVA it was not 3/4 max revs but 3/4 max power revs - that's about 10k on an R1.
(My SVA noise test was done at 7500) I don't suppose there's a chance that's what they meant?

Cheers guys - it's for Ed & Jon who have the old MNR demo car (orange.)

It 3/4 max revs at Castle Combe, 105db at the event we went to

Cheers
