My GRiSO is white. I need to do Rollerisation soon. I already have in the garage KIT C
If your bike is a 2011 it will almost certainly need an 'A' kit. If it's a very early 2011 it might be a 'B' kit bike but either way no need to take the heads off.
Have a read of my 'Definitive guide to rollerisation' to see which kit you require but if your engine has 'Floating' rocker covers with the plug tube sealed by a circular neoprene gasket rather than an o-ring as I suspect it's an 'A' kit engine.

Thank you for your interest Pete. My GRiSO have a long plug tube. But he has no drill mark in the paint on the head.

In which case it's not a 2011 build. In fact it has to have been built a lot earlier. Pre 2010 most likely.
Long plug tube and no drill mark in the paint denotes an early engine so yes, 'C' kit. The thing is by 2011 all motors had no need for the heads to be removed, (Drill mark in paint.) and from very early in the year the later rocker design, machined heads and shorter plug tube.
Can you post up a pic of the underside of your rocker cover? That will give the definitive answer as to whether it's an earlier or later motor. One of the rockers will also help identify.

Yup, early motor so yes, you need the 'C' kit if no drill mark in the paint on the head. Judging from the wavy discs I'd say it's a 2007-2009 build. Honestly, at this remove at time what year it is makes no difference really in terms of value or anything. Just fix the stuff that needs fixing and enjoy. Ask questions as needed.
