Me and Daz meandered our way up to Sheffield today.

There was a chopper jumble at the Lughole diy punk practice spot. It was grand and I scored a pair of "silencers" off Tom Deathcat for the A7.

I got the Beeza bobber back up and running, front end on the A7 nearly there too.

"New" cylinder head valves etc, rebored to +20 Harris T140 piston (the "Hepolite" piston and bore were worn out after 2000 miles), newer downpipe and re-positioned saddle with new springs.

Sympathetic bobberisation of the A7 going ok.

Taper rollers in the headstock, fork shrouds changed for ones without headlamp ears, bracket fabbed and small brass Raydot lamp fitted.

Both Beezas in bits!

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!

Been out for a couple of short rides on the A7, but it keeps killing right hand spark plugs.

It's the same cylinder that had the valve trouble and heat seized piston. Have put a hotter plug in hoping it'll bed in and sort itself out.

After months of procrastination I took the head off the A7 to investigate it's lack of compression.

The bores and pistons look fine, it's on 1st oversize, not too bad for a 68 year old bike. The problem seems to be in the right hand combustion chamber, either the valves aren't seating properly, or the head's cracked. There has been some brazing inside the head, not sure if it's to repair cracks or to hold the valve seats in. Oh, and the silicone fairy has been everywhere!
