One of those drain plugs MIGHT be your neutral indicator detent spring and ball. MAKE SURE its in neutral before removing either plug. The other one is the oil drain plug. Both will drain oil, but the neutral detent will not get all the oil out,

Sounds like classic fuel starvation. Clean carburetors, fuel lines and tanks. Fill with fresh fuel and attempt to start.

Hey Nick, unfortunately it could be several things. As Tom Diffin mentioned carb gummed up or even bad fuel from sitting all winter. If your positive the spark plug is firing (pull plug, connect to plug wire, place within a couple mm of a metal bolt, CAUTION: hold with insulated pliers so you don't get shocked, bump starter and watch for a spark) then try a very small squirt of fuel (starting fluid would be great) into the park plug hole and replace the plug. Try to start if the engine fires and then dies you have narrowed it down to carb, fuel or timing. FYI get a motorcycle repair or operators manual that describes how to winterize your bike for long storage (check library, you can read for free and make a photo copy of a page cheap). Keep us updated and good luck.

look for starter motor starter clutch will be on the end or on a chain attached to it.

The only vacumn lines on a Maxim 650 is the small line from the fuel petcock that turns it on when there is intake suction. It can be connected to any intake manifold But is usually connected to cyl. # 2 left to right. The 4 vent hoses to the carb tops just hang down the back of the motor.

Drain is on the bottom of the drive shaft. Fill is on the side of the drive shaft. Fill the shaft drive assembly to the bottom of the threads of the fill hole. Takes about 200-300ml.
