I wouldn't panic, I was rubbish on it so she's not used to going too fast anyway :D

What does it entail?

A trip to Louigi Moto would be a good start just look how our bike goes.

Weeksy, our mate Alan Shirley did my Old Senna with some vernier cam kit and pulled 6 bhp out of it, albeit with a slightly rough tickover but who rides on tickover ????

Worth it ? Certainly on the track but can be a pain in slow slow traffic.

Techincally speaking from what i can gather, it's about the opening and closing of the valves, and getting them synchronised so they open and close together and at the right times.

Chass,

Already booked in with Louigi after discussions with him and Moto Rapido

:lol: Sorry Steve, but your technical descriptions make me laugh sometimes ( meant in the style of humour not bitching!)

Heres the valve clearance and cam timing chart from my 999r.........

as the testastretta allready has vernier cam pulleys the timing was easily rectifiable

what bit is wrong then fella ?

"getting them synchronised so they open and close together"

well this bit..........

In the first instance, you need to ensure valve clearances are within tolerance and as there is a range with tolerance, you want it i would suggest to the lower end of the scale, as once the follower is riding on the opening or closing slope of the cam the less time its taking to close up a clearance gap the more pedantic it can be about at which point it opens or shuts the valve.

Once that is done it is a question of where you want a particular cam, be it for the inlet or exhaust, horizontal or vertical cylinder, in relation to that particular cylinders piston to crank position, generally spoken as degrees before or after TDC, top dead centre.

Moving the cam position can be achieved with either vernier pulleys, pulleys that have a seperate centre to outside parts so their relevent positions to each other can be adjusted, or the use of an offset woodruff key, the semi circular key that locates the pulley to the end of the cam.

Moving the cams around ie altering the timing can have a dramatic effect on where in the rev range the engines power is made. One trick on this is to have VVT variable valve timing, so under certain revs the engine is tuned for economy, and over a certain revs the engine is tuned for peak power.

I think they are looking at introducing this on the R1 at some point?

So not really that good for a road bike then.
