someone told me if I keep my Z250 on its side all the time, (bicycle, side wheelie, what ever you want to call it) that the motor can seize? Is that true?

 

no, i do it all the time

 

I would have to disagree. the motor can sieze up after doing that to long as in a length of time of running it like that but not just every once and a while. The reason is that the oil isnt getting to the pump and could not get any oil.

 

what about doing high wheelies for about 10 seconds?

 

is the oil pump by the oil filter? cause thats at the bottom, behind the clutch cover plate, isnt it?
