the #3 has a little less compression (with the stock head) than 1 and 2
the EFIs to tend to turn the plugs more "white" than the carb skis.
maybe take some pics of the plugs... may be fine

get a commercial tiny tach and check your WOT rpms so you can tune correctly, you will need it...
did you properly break in that beast? you should have been increasing rpms as time went by and short bursts of wot to seat the rings early on...
and you want to look at the porcelain`s in the plug for color...
