Heh. I'll bet. My 250LC seize halfway along the Revett Straight at Snetterton: unfortunately the other cylinder was still going strong. It made the most dreadful clattering sound after a few seconds. By cincidence I've actually got the pot of bits in front of me right now: one piston crown (complete but looks like the surface of the moon); one crushed needle roller cage; three bits of twisted conrod; one gudgeon pin; various assorted needle rollers and bits of alloy. Amazingly the cases survived but the barrel, crank & head were also written off. I found the gudgeon pin plus various needle rollers in the exhaust pipe. -- -Pip

Just a mile or so on the hard shoulder using the time honoured method of the day[1] pressing in to service two linked Belstaff belts.

I remember Mark Olson <olsonm(a)tiny.invalid> saying something like: >I drove my '64 MGB from Winnipeg to Minneapolis (450 miles) in February >1979 on three pots after burning a 1/4" hole in an exhaust valve, by >removing the pushrods from the affected cylinder.

The ShiteOld A and B series engines were perfectly capable of running fine on three. Indeed, it was routine to buy a shiteheap with a burned valve and whip the head off for a quick fix.

My CB100N once ceased to function on the way to work from Knebworth to Letchworth (eight or so miles?). It started again after cooling down and got me there, then there and back for the next two days (in small sections or a mile or two). The I pulled the engine, and drained the oil. Which looked like silver paint... The camchain tensioner blade had snapped and was being machined away by the chain. A quick=and-dirty rebuild was followed by a swift trade-in against a GS550.

Madness. Poof. I rode my ZZR1100 5 miles to the dealers after it had thrown a rod out the front of the crankcases. -- Champ We declare that the splendor of the world has been enriched by a new beauty: the beauty of speed.
