I'm wondering about this now and am questioning the advice we have provided you so far. I wonder if you may have tight valve clearances and this is causing you a slight loss of power.
Do you know when they were last checked and by whom?
Again, because I can't actually physically get my hands on the bike this is all best guess work. Your not far from Griff (Tamworth) take a trip up to see him and let him have a look over the bike, trust me when I say it will be worth it. :thumbup
Hark, is that an echo I hear ?? :devious:devious
