standing a atv on rear tires

[dr qwerty]

How long is possiable what how long do you let it sit for ever x amount of time up?

I plan on taking a 4 hour drive and the only way to fit 3 bikes is to stand them up...bikes are as follows
2007 honda 400ex
2007 honda 450r
2008 honda 700xx

What do i do after i let them sit?

shold be ok just turn the gas off and check the oil before you ride em. also check air filter for oil

" DON'T " start them up once you pull them off the truck. Let them sit for awhile to give the oil time to get back through the motor.

make sure your gas tank isnt full it will leak out the breather and turn your gas off

just to be sure that gas dont come out of the breather, tie a knot in it. i had gas leak out of a breather tube on another quad and when the gas dried on it, the gas cracked the seat.
