Quite happy with mine,than you very much.

[Jools]

That's IMPRESSIVE. Is that at the wheel or adjusted for bhp at the crank? Either way it's in 999S territory, and very nice indeed. I must admit, the thought of doing something similar is VERY tempting, although I'm not sure that I'd want to go so extreme unless I was using it mostly on track. 2800 rpm tick over seems a bit of a handful for the road...tight roundabouts must be a triumph of clutch slipping.

Don't know much about 916SP motors, but I'm guessing they come as standard with trick rods to rev to 12,300?

A 2800 RPM tick-over doesn't make sense, though. My 996RS which was far more radical engine wise, ticked over quite happily at 1600 RPM. If you have to turn it up that high simply to get it to idle, something isn't quite right.

Hi,the cams that Neil's use'd are old school race cams,i belive 431 inlet +G exhaust,they are long duration and give away bottom end torque for big top end gain.
The cams on a 996RS are short duration high acceleration cams and will behave differantly,hence the differance in tickover.

Neil is in the IOM this week so won't be answering questions!

Just got back from the IOM - what a hoot, bike was great and she got plenty of looks. I missed the DSC meet up on the Sunday though, for some strange reason I thought it was the Tuesday...
Am running a sealed airbox, or as sealed as it can be, and the dips are not noticeable on the road at all. In fact the motor is surprisingly tractable low down in the rev range, the roundabout/traffic light/junction issue aint so bad and doesnt need as much clutch slip as I thought when riding.
BHP figures are rear wheel - went past a guy on a 999R on the mountain, had a bit crack at the creg, he reckoned he was giving it the berries and couldnt stay with her. Not so surprising really as the diet shes been on has liberated 45 - 50kg from her all in weight.
Dont forget theres no lights etc and everything else is either mag or carbon - so power figures dont tell the whole story.
Steve thanks for highlighting the difference with the older cams.
Oh yes the rods are Ok to that - 1st thing I checked out.
cheers

What kind of clutch parts does the bike fit ???

[851neil]

Phil, an STM slipper clutch is fitted along with sintered plates, not seeing any slippage so I guess that the combination is working Ok for now.
I'll be checking the pack height carefully as I don't know what it's life will be !

[phil911]

Your feedback should be very interesting ...
