Me Z750 on the dyno (vid)

Had my Z750 on the dyno the other week at the VTR dyno day. Only 'power' mod is a Blueflame twin-exit oval pipe with bottom baffle drilled through rather than removed, top baffle still in. Result was 103rwhp. We had to do a through-the-gears run to see if it was running lean/rich as the lambda probe wouldn't fit down the blueflame properly. It's running slightly rich (no power commander) so removing a baffle would gain a bit more power but would be too loud for the road (already tried it). Curiously, the fuelling in 4th is almost spot-on and it nudges 109bhp, 5th/6th are 103bhp or thereabouts though. I thought 'optimistic dyno' but it was giving 103-108bhp for all the VTRs which is spot-on and consistent with the same bikes on previous dyno events we've had.
It was weird to discover that there's about 3k of revs I've never used, the limiter doesn't actually kick in until the tacho shows 14k (alllll the way round). Ah well! I've always changed up at 11.5k or near as dammit.
