So we're just doing a/c and slipons....Then I would do two things.
First..there will be a down load in the SERT for your bike ..for the 4.12 version it would be 127hm005.
A couple of edits to that map should be made. The target a/f ratios for both cylinders should be reduced down to 14.0 at any cell where they are higher.
These areas are in RED.
The Decel Enleanment values can be safely cut in half...Dont know what slipons you are using....so it wont pop on decel. It will now run better than just loading the stock map in the sert.....run a little cooler..be a litle richer.
Secondly....do as Mega and Chuck suggest...spend the money to have it run up on a dyno and tuned completely...Idle..midrange..full throttle. My need many adjustments ..may need just a few as there are really no modes done other than increased breathing....But you will know.
Will these be all you ever do? Don't want you throwing good money after bad.
If your dealer or favorite independent shop has winter sales, you could probably get Andrews 26G cams, adjustable pushrods and a Baisley spring done for that, but it would be a poor choice if you were going to do heads later... Depending on the shop's winter labor rates, maybe a 95" as well, boring your cylinders and using SE cast flat top pistons, but that'd probably take you a little over. If you had the 95" conversion done, you wouldn't need the adj pushrods, though, as they'd have your heads off...
