yeah saw them, ouch im getting up to 60 hrs now on my piston ,had two rings in the mean time so not so bad but will overhaul before something bad happens ,looks like the new conrods from tm are quite well priced so ill do that and look at a double ringed wossner ,got to figure out what size yet I think my barrel has got a c stamp but last time I pulled it down the piston had size markings for a a stamp so a barrel measure might be required I think.
