I've not posted for some time, couldn't be *rsed, nothing really worth looking at. Not been idle, mainly trying to get the A7 running right (new rings and a hone, several carbs later it's not too bad), stripped the B31 to fit another head and found the bore and rings worn out after 2000 miles! Bought an SR250 for no good reason, got it running, repaired and back on the road after a 10 year rest. I've got pics, may do a phone dump (as the kids say) later. Oh, happy new year!
