Re: Standing it up on its rack?
Not draining the carb and tank will cause fuel to pour out of them when you stand your bike up. Not the best thing to do, I would also like to mention that on some bikes oil may come out of the breather hose. Otherwise, it should be fine to stand your bikes up in your truck or trailor, I occasionally stand my bike up to acess the bottom for doing work on it.
