heard mixed results regarding this mod, not sure on compression/carby/fuel ratios etc differences between the YFZ and YZF but dont after some stories ive heard i dunno if id be fiddiling with the cam timing (especially on a new bike under warrantee)
May be just me though being over cautious |

we did quite a few of our YFZ's like this and a couple of them with the full YZ450 cam change over, changing the cam timing like this moves the power a further up the rev range but will lose some grunt off the bottom. well worth doing for an MX quad.
