I fitted the kit last night & first impressions were, bloody hell thats quick. Power is at 10.9 ish with just one of the spacer/washers fitted.
Off to the club with it tomorrow for a proper session but early indications are that this is the springer that I have been looking for. Many thanks Nick
So this is one of those lightweight pistons, with an unaltered transferport?

Can I ask what spring you are using?
