It's important to properly warm-up the engine. Heat cycle the engine a couple times using varying throttle up on a jack stand, no higher that 4000 to 4500 rpm's. Making sure you don't overheat the engine. Then when you actually ride it, use varying throttle with short bursts of wide open throttle for the first tank premix gas. Then always properly warm-up the engine. Longevity of these high compression engines depends on it.

as far as the motor and oil ratio i wouldnt be concerned with any break-in... these things are running very rich oil ratio bone stock... my dealer actually told me to only use half as much pre-mix in the tank... :dance2:
thats rediculous... if there is something wrong bad enough to break down under those conditions, no amount of oil is going to save you... :flush:
i didnt add any pre-mix...
and after 200 miles i adjusted the oil ratio back up to where it should be...
50 to 60 to 1 ratio...
if you do add pre-mix definatly change the plugs after that tank...
im not saying that nobody should add pre-mix... to me it makes no sence... you do what you want... :beerchug:
as far as break-in i would take it easy the first 30-40 miles for the belt... those things are too expensive to break... :doh:
always make sure you give plenty of warm up time on these F-chassis sleds...

The premix is a good idea just incase there are air bubbles in the oil line from the factory. By the time a full tank has been run the air bubbles are gone. My buddy blew his sled up exactly for that reason. He always runs a tank of premix now on a new sled. :flush:
