Phil,
I had SP cams & pistons fitted to my 748Bip in Feb during a top end refresh (valve seats, lapping, 16 new rockers etc). Also had vernier pulleys fitted and the cam timing adjusted.
All the work was carried out by MotoRapido, and it produced 101BHP before it rolled out on the road (probably more now it's loosened up). Cost of cam timing with Verniers was around 5 hours labour, plus the cost of the pulleys (about £250 iirc)
Since I had all the work done at once, I can't tell you how much difference the cam timing made, but it goes like stink now
