Hi Rudy, I have not been able to get any parts, so had the piston bored oversize & the gudgeon bush bored out to suit, then the machinist made a new gudgeon pin to suit. Not cheap $250.00 all together. Now I have to find some rings there is a place here in Perth that may be able to get them, he is hard to contact as he wont answer the phone all the time, also the rings need to be about 25thou thicker as the ring grooves need to be machined as they are not true. that's where I am at the present time, all been put on hold for a while. Regards Noel.
