Yamaha ATV Stored Standing Up Q&A

Hi John, I’m tight on space, so is there any harm in storing a fuel injected Yamaha YFZ450 standing it on end for a period of time? 

John Talley: No. It shouldn’t bother it. I’ve seen dealerships do that before. The only thing is your oil is going to all go all the way back. I don’t think it could make it into the overflow tube for the crankcase, but if you’re really going to stand it there for that long, go ahead and drain the oil out. That’s what I would probably do to keep that from happening. Just make sure you put a sticky note on it or a tag or something that says there’s no oil in it. [sarcastic] Not that a dealership has ever started up a unit without any oil because they didn’t know it was drained [laughs]. But no, I don’t think that would hurt the machine at all.
