Every motorcycle I know of uses the petcock to change between reserve and regular......as well as having an off option. Some petcocks are vacuum operated so there may not be an off.....but there will still be a selection between regular and reserve.....and usually a prime option.Is there a switch to turn it to reserve from regular and vice versa? If there is, where is it on a 1981 KZ440 Ltd?
Well I know thats not the case.....cause I have a bone stock 1980 KZ1000 that has a manual petcock. Im pretty positive the Ninja model line into the mid 90s had manual petcocks....atleast from the rebuild kits Ive been looking at.I'm pretty sure Kawasakis started using vacuum petcocks in all their bikes in the mid- to late-70s.
