im coming over to the dark side

So, as a total newbie to the R1 thought id say hi and ask about this bike before i part with hard earnt money, here are some pics and a writeup of the bike and what ive been told , its in Blackburn bought by owner from preston superbikes a fee yrs back.
Matris rear shock , Matris front suspension, Gubellini steering damper, Double bubble screen, Single seat cowl, Tail tidy, Pazzo short levers brake and clutch, LED flush fitting indicators, Led rear brake light and indicators combined, Galfer front and rear contoured brake discs, Goodridge brake lines, Alloy engine crash bobbins front and rear, Alloy paddock stand bobbins, Gilles rear wheel / chain adjusters, Harris adjustable rear sets, Billet alloy bar ends, Alloy clutch arm cover / guard, Micron exhausts, Billet oil filler cap and a Power commander III
Also there have been a couple of handy modifications made such as the welded / reinforced swing arm which is commonly done and a headlamp with has been added so you can with the lights off instead of them being on all the time.
This will be perfect for somebody who enjoys all the toys and likes to have all the different ways to set the bike up to their preferences such as the suspension, the riding position with the rear sets of course the power commander to play with.
The bike has a slight stutter at 4k and im hoping this is due t power commander, can these be removed and the stock ecu then takes over, not familair with power commanders as my gixer was carbed
cheers for any input, good or bad, let me have it lol
