Yeah Geoff its the same dumpvalve mate but its not a constant problem its only happened twice,thought that it might be related to the problem ive got at the moment with the battery.The battery has had a cell go weak and it really struggles to start after being left for 10 hours or so.herritage wont have anything to do with it and wanna charge £81:41 for a heavy duty battery.If ya wanna meet up mate no probs get steevo to come too and we can go for a drink too
Cheers Alan
