help with my polaris virage tx 1200

[fireblade1545]

hi, need help with my polaris virage tx 1200,
the engine has a top end rebuild and complete electrical refurb, after starting it - i had a good low and mid range throttle response,but will not open to full revs, when it also smokes a lot ( white smoke like unburnt fuel) ?
i was told by someone to check the crank index to see if was out of line, i have checked this and found that there is a 1.5 - 2.00 difference between cylinders.
my question is - is this critical ? or within tolerance acceptable?, would this cause the motor not go to full revs ?
(these tests have been done out of water)
if this not the cause - have checked carbs, electrical hoses etc. basically run out of ideas, any help would be most appreciated thanx kev.

Welcome

Does the MFI display have any warning message or say "Reverse"?

What year is this Virage TX?

Carburetor engine?
