As above, but change the oil when hot after the stabilizer has been added. As long as there is a Battery Tender on it, you can leave it in the bike, as there's no reason to remove it.
I always treat my leather (and a good washing)8 on my bike before winter storage. In the spring it's a quick wipe and away I go.
Lube anything I can as well, check tire pressure and so on.
Come spring I go through the entire bike looking for loose bolts etc, recheck tire pressure, give it a once over and away I go.
Ya, I ended up doing an oil change, filled up the gas tank and added stabilizer. I took the battery out and left it on a battery tender. Took the bike out 2 weeks ago when we had that warm snap, she fired right up.
Just gotta get some room in the garage to install the shift kit, and a few other bits and pieces, then she'll be ready to rock and roll! ABOUT TIME!
