I just bought a 06 M7 141 Efi caryover. Goin from the F to the M sleds is there anything I should know. I was thinkin about doing the vent mod just to keep the cool air to the clutches. Any other suggestions. Coming form So Dak I was going to use 66g weights for riding 8000-10000 feet "for the trips out west". What g weights have you found works best for this elevation. Any other suggestions or input would be appreciated.
