G'day Brendon, You CAN get some rings for these engines. Contact Grahame Burling on
02 9452 5784. The size code is 48 x 3/32 x .070" . www.gsburling.com.au
I have spoken to Grahame and he carries this size as a stock item. I ordered a set this week - 13/10/15. Please note that these are STANDARD bore size rings - if you want oversize (unlikely) you may be in trouble but speak to Grahame anyway. NOW, IF ONLY THERE WERE A SOURCE FOR THE SPLIT NEEDLE ROLLER BEARINGS FOR THE BIG END AND THE WEIRD SIZE ROLLER BEARINGS FOR THE LITTLE END................ anyone know of any ?
If anyone knows better than me how these forums work might like to spread the word on the piston ring contact in a new topic or the relevant section.

Cheers,
