How much oil did you put in? What does the sight glass show? Did you put back the screen, spring, and washer behind the drain plug? Any chance something fell into the oil filler hole or into the new oil filter?

Was the fuel petcock turned off? I had a major problem with a previous bike hydrolocking when I left the gas on.

If you always drain the oil from the bottom center plug instead of the left side, maybe the screen is blocked with debris and you don`t know it.

well I've only had the bike 3months and never really ran it,and only changed the oil twice.If the screen is blocked would that lock it down?
I never heard a sound in this motor until I changed the oil.
I have all the plugs out and still can't get it to do right.

the oil sight glass is on the left and the oil filler is on the left... you did put the oil in on the left and not on the right?, because the right is the coolant sight glass and filler.

If the screen is blocked it could could prevent oil from getting to the oil pump intake I believe. That could seize the engine if it ran too long without any oil pressure.

3.5 quarts sounds a little low my manual calls for 4.2 quarts when you change both the oil and the filter,
even if it was half a quart low that shouldn't be low enough to lock it down.
I have no center stand on mine,previous owner removed it.

hmm i don't really have any advice for you there, i know from growing up working on cars with my grandfather that if a car engine locks up it usally results in a overhaul of the engine, and probably if you do get it to turn again there could be damagle done to the rings which would still result in a overhaul

you would be supprized what a half a quart low can do and that was actually closer to a whole quart you wasn't but 0.3 quarts away from being a quart low

could it have overheated? that could cause a seize also...
i've seized a tractor and a dirt bike.. both required a rebuild.

Not trying to ask a silly question, but here goes. Are you sure the engine is seized as opposed to the starter simply not turning it over?

I was thinking the same thing, put a set of jumper cables on it and try it again.
