Just had a touch of bad luck. I just heard back from the machine shop and I’ve been told I need oversized pistons. I originally ordered standard size from Paul at RST but that was 8 months ago when I was gathering up all the bits etc and I am now unable to return them or swap them over. Would anyone be interested in buying a brand new set of Wossner forged pistons from me as I now had to order the larger size? They orignally cost me £495.00 +vat. Happy to work out a deal for anyone that is interested as they are no good to me now.
