Hi Mark,
It's recommended to stake them screws with a centerpunch.

Hi Zem, You could do as I did and mount a car battery in the sidecar boot. I threaded the battery cables inside washing machine water hoses(no chance of shorting) used rubber grommets where they passed through the boot floor and led them up to the bike. The battery weight in the car makes for better...

Are you sure its a collet issue? looks to me like the valve spring cup broke up (they look thin and flimsy in pic). Great looking bike by the way, can you gear it up for less rpm?

Hi,
The enfield regulator gives problems at only 100 watt output, I think at 200w you need a better one.

Re: 1974 800cc V twin in BMW R80 Frame.

Hi,
If the oil level drops too low the crank webs stop throwing oil up into the bores, the oil pump still supplies oil to the bearings etc as its at the bottom end of the sump. Hense the piston overheats and locks up.

Re: Blown up engine.

Hi,
Looks like lack of oil, I would think your oil level dropped below the level of the crankshaft webs and so was not throwing oil up into the bores hense seisure.

Hi Mouse,
It's gonna be great. To allign gearbox take the flywheel and clutch to your friend with the lathe and ask him to center the friction plate for you, once under spring pressure it wont move and will allow you to mate gearbox perfectly.
