I'll jump in here. I keep my bikes in the garage if that is possible;e for you others. Full gas, petcock open and start them once a month. and try to ride them once a month even if it is just around the block. I remember when my brother and I would go for a put every Xmas day high sun late noon, snow ok if plowed, but we were young and dangerous. Now I just go in the garage and stare for a while and start it up.
Some thing about bikes they can do that to you. Just look at them for a while thinking about the next thing you want or , how good they look at certain angles, or just how nice the machinery is, LIKE A HOT DANCER AFTER A COUPLE OF Scotches, you just feel like throwing some money at them.
