Yea! , found my way back to Yamaha after a few years with a 2005 Rev. Had only Yami's for 25 years before that. Just bought a 06 RS Vector GT. This is my first 4-stroke sled. (This is the carbed 3-cyl). I got a smoking deal (I hope) on the Vector GT with only 1,365 miles on it. Basically a barn find. Had not been registered since 2011. Sled would not start (bad battery and old gas), but it was obvious it was low miles since no wear on track, skis, and skid super clean. It was a take or leave it deal "as/is", so I bought it for $1850 and brought it home. No owners manual.... Although the sled was dusty, it appeared to have been stored indoors or in a covered trailer. As a precaution before startup, I put some fogging oil in the cylinders for a couple days, turned the engine over by hand about 10-15 times over a couple days, drained out the fuel tank, and added 5 gallons of clean premium with some Seafoam, used a pump to prime the fuel system, put in new plugs, and new battery. I also disassembled the fuel pumps, which were already super clean inside with no varnish or debris. So, got the engine to start, but was not aware that u should not run these without the air box. Engine ran maybe 30 seconds without the airbox, and oil dumped out of the larger hose running from the oil tank breather valve (?) into the end of the air box. Lost probably about a pint or less before I noticed the oil dumping out. Only after looking more closely at the label on the airbox did I notice the small label that said "running engine without all air box hoses connected could lead to severe engine damage" The engine was kind of noisy/rattled sounding when I turned it off. I put the air box back in with all hoses connected, but the motor is still noisy..... Could I have I have damaged the engine in those 30 seconds before I put the airbox back in?
