I was looking at different cams and wanted to know if the conversion is possible with little or no modification.
I figured I'd go with regrinding, but there is higher availability for parts f all sorts on newer model years. ThanksIf this is about 1000RR the only difference is the intake cam. Exhaust cam is same. You will need allso 06-07 valve springs to the intake and 06-07 ecu whit higher rev-limit and the difference is few hp. Probably smarter to get the cams regrinded and still you might need the springs for intake or bouth and 06-07 ecu.
Webcams doesn't list any regrinds for the 04-05. All hardwelds and very pricey. For the 06-07 they have few regrinds but if are going to use some smaller shop i would show the cams and ask what they can do to them.I figured I'd go with regrinding, but there is higher availability for parts f all sorts on newer model years.
