Sorry its been a while but I've been enjoying my A10 plunger !
Basically its all fixed now (for a while) and runs very nicely.
From what I can recall from the lasts posts...
1. I found a new gearbox casing with good mounting holes except threads. Helicoiled these, put correct studs in, dressed frame where it had worn, made custom shims to put the gearbox in the right pace and bolted in firmly in place with strong Loctite. No probs since with loose mounts, loose nuts...bad memories of getting the engine and gearbox in and out of the frame many times until it 'sat' right.
2. Bottom end rebuild was done by T and L engineering. Original problem was excessive timing side bearing clearance. Sludge trap found full of crap which probably caused bearing failure after only 1000 miles since original rebuild. Very nice job by Tand L , including dynamic balance. Has transformed the bike, nothing breaks now with vibration. Have included the balance sheet for the techies !
3. Old thin flange barrels were cracked, found some thick flange ones (not cheap). T and L supplied new pistons to suit new barrels.
4. Fitted progressive front fork springs and two way damper rods from Goffy.
5. Put the gearing back to solo ratio not sidecar,,,,
6. Fitted a Digital Voltage Reg (very effective and fits in old electro mech box) and a AGM battery again from Goffy.
Think that's the major upgrades. So far so good, done 2000+ miles no issues.
Hope you like the pics and thanks for the advice and help I have obtained from the forum. I've even fixed my mates Laverda 668 as the Beezer just keeps going...bloody fuel injection, who invented that.
