Does anyone have any data that shows the differences in required fuel trim for the rear vs front cylinder on a monster 1100 EVO (or any air-cooled ducati 1100 for that matter)? If no data exists, is there any general consensus about how much leaner the rear cylinder typically runs compared to the front when cruising on these air-cooled bikes?

Since I can only tune off one cylinder at a time with the bazzaz kit I have coming, I'm thinking of tuning off the rear (hotter) cylinder first to get my first custom map, then load that map for both the front and rear cylinders. Then, I may retune off the front to see how much less fuel is suggested by the new map. Does this seem to be a reasonable method?

In the end, if I can get some approximate delta between the two, I can tweak the front vs. rear fuel map according to the difference.
