March 27, 200619 yr Moderator Yes andNo you are not on the limit of available pistons I think yamaha only did pistons too 1.5 mm over but you can get pattern pistons too 2.5 go for quality ones Prox or Mitaka or wiseco make sure the borer knows what he is doing as well Stans Stephens or Prox engineering shouidlknow waht they are doing www.prox.co.uk for prox www.stanstephens.com for stan stephens merv
