Has anyone swapped out the vacuum assist petcock on their 360 for a standard one?

  • Ahh Mike Kristin you know all the fun :) Go for it, find an XS650 one or similar on ebay, it'd be easy enough to make up an adaptor plate if the new one is smaller.

  • I have a RD350 that is manual. I wonder if that will work for an XS.

  • Josh Bohman that's kinda my problem all the resources don't really talk about size patterns

  • As long as the new one is smaller length wise and about the same width then the adaptor plate is a bit of ally with 3 holes in - no welding required, easy fab with a cornflake packet template.

  • you can modify the vacuumassisted to a standart one, if you are able to understand german, read here, but use something that can resist the petrol to fill the gaps...:

    the other option is, to make an adapter like this:

  • The one I want to switch is on my dad's '81, but I bought a '78 with a good petcock, so may put mine on his. I think I might put a peanut on the '78 and hard tail it.

  • Mike Kristin, there may be something on the xs400.com forums. I know I've seen this issue addressed somewhere.

  • This is what I did with mine it's a xs400 with a Harley tank and a brass petcock.
