Since I will have the bike's fairings prety much off and the bike naked for maintenance I plan to replace all the vacumn hoses too. anyone know ho wmany and what size they would be in a 1990 ex500?

im assuming the vacuum hoses are the black rubber things and not the clear plastic hoses ...right?

 

[knightslugger]

there are only two that i know about. one that goes to the petcock and one that goes to the smog system valve.

NEVER !!!

 

[dansdad]

as long as it fits....why convert?

anyway, just to be sure...does gas go thru these hoses or air? and what do these hoses do?

I think tubing is all imperial actually.

well... vacuum goes through the hoses. maybe some air.
