oil, as well as all other fluids, will drain to the back of the motor if your "new oil level" is above a overfill valve or any path of escape you may dump your oil. and if you do not realize it you will be an accomplise in xx homicide. plus you may just get oil in places you dont want it.
I know Wayne Matlock will haul his parts quads this way from time to time during a race. You need to block off the breather line, or else oil will drain out of it, alot of oil. I think Wayne just uses some type of clamp to pinch the rubber line. Other then that, I don't think he has had a problem.
I stored by buddy's machine in my garage. I noticed a huge oil spot on the floor, we think it was the crank case breather leaking. when we changed the oil the next day not much came out. I won't be storing his or my machine on end ever again.
i hope it will be ok because that is the only way i can fit it in my toy hauler with our rhino and i am veryyyy sick of driving our rhino. so what breather needs to be blocked the crank case or the one that goes into the air box. one other question what makes the 700xx differant from the other sport quads cause my z400 had no issues hauling this way
I have stored mine on end and been fine, but after my buddys leaked oil all over my garage I'm not going to trust it like that anymore. he said it may have something to do with where the crank stopped when the machine was turned off leaving a gap just enough for oil to come out the breather, i'm not sure if that's true but it only takes one huge oil spot in your garage to realize it's not a good thing to do. (I do like the valve option though, i'll look into that)
400ex has been hauled this way many of times, rule of thumb from what i've heard/read. Make sure you let it sit level for 1/4 of the time it was standing to let all the fluids work their way back to were they go.
