Ok I have another question. I noticed that at idle the bike runs a little rougher then usual. Bike runs strong and responsive now that I have retuned it. But I did noticed that the rear cylinder exhaust had a raw gas order while the front exhaust had no raw gas order. So my question is which way do I need to move the VE table for the rear cylinder to lean it out a little.

Before manually changing the VE's, make sure the idle cells are in closed loop, set the idle speed to about 800 rpm's, and then do another vtune spending some time at idle.

Sometimes it helps to lower the idle and let the system work to stabilize the VE's...just don't idle for long periods of time and after the vtune session, return the idle to an appropriate rpm for your bike.

See if that helps...
