Hello,

I ordered Ferrea VG1056 and VG1058 valves guides + Valves + valves seat.

I removed the stock valves guides, and the outside diameter is 11mm, but your Ferrea VG1056 and VG1058 outside diameter is 12mm.
Can you say me if it's normal ?
I must to adjust the hole in the head to 12mm, or adjust the VG1056 outside diameter to 11mm ?

Thank you.

 

I've never done guides so I cannot tell ya for sure, but they should just press in there. I would call Ferrea just to be sure.
