What is involved or is it possible to fit a WR or similar fuel tap with reserve to my 08 YZ450? What is the easiest way to go about it and will it fit straight on?

Thanks for any replies..

I think you can just order a WR petcock that will bolt right up. I know I could do this with my 07.

Yep, just throw on a fuel petcock from a WR.

Check this old thread, the end addresses the petcock issue. Like I said I had the choice of WR or YZ when I bought mine. I'm sure the TT OEM store could help you out.

'07 or later, so that the form factor is the same as yours.

When you run out of gas, you switch it to reserve and have enough to limp home. Say, how much would the WR petcock leave you in reserve?

A reserve fuel tap is basically there just to let you know when your running low on fuel. The bike will run out of fuel or start to when there is a litre or so of fuel left in the tank, then you turn the tap and use whats left in the tank.

I too would like to know how much fuel a 08 WR fuel tap would leave in the tank when set to reserve? Anyone know?

I always thought that bikes that had reserves on them had some special section in the tank. Thanks for the info.

No the main pick up tube is longer than that of a non reserve fuel petcock. So instead of having one tube, the reserve fuel petcock has one long tube and one short one.
