No, I've got an 888 and that's the style I want. I love a project and am very happy to play. Who knows, over time, it may evolve to the narrow head motor. For this winter, we have a pile of bits on the shelf and a simple plan.

Looking for that powerband rush (big smile) at 8k that these cams will give.

It'd be too easy to change bikes for power reasons alone. We'll have a few toys in the toy box, enjoying the one to suit the day.

Rgds, Rob

Nah mate, been there, almost binned that :P
I'm trying to impose a survival limit by keeping below 100bhp, but I miss the grunt of a 900 engine when I'm riding the 748.
And no, I dont want a gixer (done the mallory school) cos they might as well be strokers for the amount you have to rev them to get anywhere - I've got a 'four' working in its design envelope in my vw box :P
Give me twin-power any day.
I just want my 748 to work as well as it should, not just ok.

Phil,

Agree, totally. Sorry about the thread hi-jack. I assume you have seen the Moto One and Neil's (Sigma) sites. There's a good bit on getting the best ot of what you've got. My 996 is dialled in, set up on a good FIM chip, and is a pleasure to use. Now, I'm looking for a step.

Rgds, Rob

Just out of interest how much are you looking at to have the cams dialled in...?

[phil_h]

I've not enquired about setting up costs, cos I'm considering doing it myself ...
the only example I've found is moto-one, who charge: (at just over A$2 to the £1)
A$760 for 4 valve Ducatis. This includes all parts and labour.
(Adjustable cam pulleys cost A$120 each)
Everyone else says they'll work their magic for a fee (but dont ask them what it is )
So far as I can tell, the 'magic' is to advance the inlet cam about 6-10 degree from factory spec. (Advancing any inlet cam on any bike will move the torque curve downwards at the expense of the peak power and I've played with that on my velo racer.) The magic is knowing where to compromise

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
