Seem to be hitting around 68mph in 5th so not bad at all. Not gone all out yet. Might consider a 14t yet as I reckon it will struggle in 6th until over certain revs??? Had bit if ball ache today though. Noticed a tiny water leak on head. Thougt it was coming from spark plug blather inspection the cylinder head has small crack where the 3bn writing stamp is
!!!! Had to put spare on and torque up the head. Seemed all good now!
