Question re washers on Engine mounting bolts for a 1200

[sfcpiet]

sorry piet,series two 180's are NOT sewn together useing BLACK socket caps,you did at one time see them all over the place (cheap ones nicked out of the works stores perhaps?) and yes that 1200 annivesarry was one hell of an ugly pig.

Never mentioned them being BLACK, Clem.

The factory always used 8.8 tensile bolts on miscelaneous fixings, 10.9 fine threaded on engine mounts and similar.  750 top mounts are normal thread pitch (before somebody slams me on that ).

Curiously, the Zane factory fitted their bikes almost completely with stainless nuts, bolts and washers, a real pain in the arse when you drop one down the cam chain tunnel..... the engine mounts are plated 10.9 steel, though, guess they knew why!  Because the majority of the stainless bolts are threaded into bare aluminium alloy without lube or other protectionary precautions, all manner of difficulties crop up on disassembly, corrosion plays its' havoc!  The factorys' love of domed socket head bolts makes itself felt especially at the oil cooler/radiator mountings on the cylinder head.  Most are rounded at the first attempt at loosening and need to be drilled out, a really fantastic solution to a problem that would never arise if Luigi & Co. had selected the correct fastener for the job in the first place!!
