Relative newbie to Rotax however at Shenington this weekend struggled throughout to get top end revs - averaged 12,600 when should be nearer 14,000. Overall engine felt very lethargic no urgency in acceleration.

Cleaned:

Air filter
Carburettor
Pop off valve (could not sense it coming in but, as I understand that should be the case anyway. Certainly no surge was felt when/if it came in)

Gearing: 81T

Battery: measured 12.6v

It maybe ready for a top end rebuild however before i go down that avenue I want to exhaust (pardon the pun!) all options as to possible causes - suggestions gratefully received!

thanks
