Is there any advantage of having the sp exhaust cam?As Im having my engine refreshed just now and my mate has noticed that it has a reprofiled adjustable inlet but what looks like a standard exhaust cam.Is it worth me looking for one?cheers.Robbie

Hi Rob,

Do you use the bike on the track ?

Are you likely to "dial" in your cam's differently from one month to th next ?

Do you want to eek out every last drop of torque and power in the motor on a Dyno so can take advantage of having adjustable cams ?

If yes then it has to be worth while.

MM!

It is my race bike.So every hp helps but dialing cams in every month no.why would I need to? I dont have much of a clue about the tunning side.Just wondered if it would be worth the expense getting the 2nd cam?Engine is totally std bottom end,ported/skimmed head,Adj inlet cam and ram air.need every hp I can get obviously.But on very tight budget.
cheers

Idea of slotted cams is dialling them in for different tracks to get best performance for that course.

Otherwise your best to get a static set like the BEET ST-R that are race oriented and the grind is optimal. Then mess about with gearing for the course.

ZX4-F3 static cams are also meant to be a good track cam to use.

I'm sure my SP / F3 notes say to set the slotted cam's at 6' for best performance - but will need to check this. This is also using them with a F3 CDI so don't know how that goes with just the road version. The F3 set of cams I have look to be already set at that and when I fit will run as is.

MM!
