A new-to-me, unrollerized GRiSO is currently in my garage.  I'm trying to figure out which roller kit I need, but I'm a bit confused.  On the AF1 website the flow chart goes:

O-ring groove on the inside of the valve cover?
Yes -> Kit A
No -> Continue to the next question
Is there a punch mark on the inward facing exterior of the head?
No -> Kit C " This Kit can only be used on bikes that DO NOT have a punch mark on the cylinder head"
Yes -> Kit B

Then Kit B says "For '09-'10 Moto Guzzi Stelvio with Early Type Valve Cover* and Punch Marked Head**"

At the same time, a printout on the Guzzitech forums suggests that the GRiSO either takes kit A or kit C.

What year is it? This will help. Also does it have a circular gasket of the same crossection as the main rocker cover gasket around the hole in the rocker cover?

Basically if it is a pre late 2011 it will need either a 'B' kit if it has the drill mark or a 'C' kit if it doesn't. If it's a 2011/12 and it has the gasket mentioned above it will need an 'A' kit.

Can you post up a pic of the inside of the rocker cover?

The bike is a 2011 (B code) that left the showroom floor in December of 2010.  Everything points to kit B being required, though I didn't know Grisos ever used the B kit.

Yup. 'B' kit. I note that in the US all the kits cost the same which is a bit weird, (Going from AF1's price list.). $1,226 seems to be the price for A, B & C kits which is a bit odd.

Two Lamers price on a 'B' kit is €668 which translates to $745US which translates to a respectable saving.

This is what you want. Make sure that when you order you confirm you are in the US, (It's all in the website but I have an account so I can't remember the exact procedure.) otherwise you'll get hit with the European VAT or whatever they call it.

Your price should show up as €668.36. Thumbs Up
