Have you taken it for a drive ? Big difference from whats on paper to the way it actually drives.

Et le prix ?

87mm pistons I assume, not 97mm?

Unfortunately no chance for a test drive until I get home and go to complete the purchase.
I was more wondering if this is a kind of "regular" build?

The other thing that slightly concerns me is the clutch. Although its only done 2300miles as it was fitted with the new engine. Its only a stock clutch.
Any opinions on whether this is just totally inadequate or should I get the life out of it then go for uprated?
