The YZ is starting to get abit rattly in the top end, haven't had a look yet but are Pistons easy to come by ?

Mick - Speed and Sport list lots of pistons through second oversize - but not cheap.  NWVCP list nothing which is quite surprising and these are 250A pistons - some of the other guys will have to come on and advise of whether DT pistons etc fit the 250A as happens with the B's.

Not much genuine listed on Ebay either.

Hope that helps

I'm sure the DT2MX pistons will fit but use the YZ rings if you still have the chrome bore . Iain
