I don't know about this particular model of Shadow but most bikes have seals on the tube mouting ports, aka the pipes that are bolted to the engine and allow the tubes to be secured to the cooling system. If it's just a seal leak you might be able to very carefully (this may take several hourse of gently turning a wrench, if you strip the bolts you WILL have to take the engine apart, and that's probably gonna cost you a couple of hundred bucks minimum) unscrew the mounts, take the piece out, replace the seals, and screw it all back together. Good luck and check your manual!
It is possible that the gasket could leak between cylinders. The overheating and coolant loss would happen if the gasket was failing around the coolant passages.
A misfire is when one of the cylinders is accelerating without actually doing anything, it's just a dead-cylinder. In order to fix this you need to tighten the cylinder or adjust the engine connector.
Anitfreeze IS coolant
Depends on the market. Displacement and number of cylinders don't go hand in hand - there are 15 and 16 liter diesel engines with only six cylinders, while there are also V6 engines with higher displacement than engines from other manufacturers with more cylinders. TYPICALLY, you'd be talking about a four cylinder engine, but we can't say for certain without knowing what that engine is (make/model/year).
White smoke is coolant in the cylinders. Died and won't restart cause the spark plugs are shorted with coolant. If you keep trying to start it without fixing it you could bend a rod! Most likely it is a failed intake manifold gasket or intake plenum gasket or the intake plenum itself. Don't drive the car cause if it is the plenum leaking coolant into the engine it can fill a cylinder with coolant and do major damage when you try to start it. No way to know for sure which of the three it is without pulling the plenum. If you're pulling that you might as well change the intake manifold gasket too. Could be a bad head gasket

You can buy coolant that is premixed and is added to the radiator without mixing.
Can anybody drive a vehicle (F-150) 4 miles without any antifreeze or coolant?
You've lost all pressure on the clutch cylinder. I can't tell you if it is the master cylinder, or the slave cylinder, or just that you have a slow leak and ran too low on fluid without being there to see it. Check the fluid level, if it's low or out refill it, then pump the clutch by hand in and out and check to see if the fluid is running out anywhere, the hose between the two cylinders may also be damaged, but you'll have to find that leak to be sure. If no leaks are found then it is probably a slow leak, you can bleed the system and get by for a little while but replacing the leaking part will need to happen soon, it is most likely the slave cylinder though, they go bad much more often than the master cylinders.
It sounds like the valve guide seals might need replacing. As you go down hill (no throttle), oil is drawn past the faulty seal by the vacuum from the cylinder. Job can be done without removing the cylinder head if you have the right tools and knowledge.
Without oil, there will be no lubrication. Metal will be moving directly against metal, without a protective oil layer in between. This will cause heat and wear. Pistons can seize in the cylinders and bearings will wear out.
drive it without coolant
