I've used this for TB sync works fine. I would not use brake fluid, nasty stuff. This has the potential to get sucked into the engineor onto paint. Either use very thin oil or water. Also if you increase the revs when out of sync the high column leaves a film of oil / fluid on the side of the tube and this takes time to get back to level if the oil is thick.
Automatic transmission fluid works fine...usually red and so can be seen easily and doesn't stick to the side of the tube too much.
Been using a home made set up for ages, works better than any vacuum gauges I've seen.

I made my own using green brake fluid - just cos i had some around - no problems.
If you do it right the fluid level is about 1metre from the engine anyway looped up and over the 'bars
Red ATF is probably better though.
......and so what if oil gets sucked into the engine ??

a 'possibility' , yep.
but you'd have to be pretty slow to stop a whole load being sucked in from a manometer.
also - water ingestion from going through fords and stuff - same deal .
twisted crank ? not on a beemer - a pressed up roller bearing crank maybe ?
bent con-rods ? you'd need a LOT of oil.

well i've personally seen several bent con rods & the odd twisted, forged crank in car engines that have ingested water or just dropped valves, so it certainly CAN happen. admittedly they were diesels, so the compression ratio is twice as high, but the con rods & cranks were very much more heavy duty than the comparatively flimsy things bmw use in bikes.
like a said, it's a possibility. how much fluid would it need to raise the compression sufficiently to lock i wonder?
i suppose charlie & ewans bikes did take in water several times on their trip & there appeared to be no harm done. i must say, i was surprised when i saw that.
of course you might need a dial gauge on the piston crown to spot the damage
