KIBBLEWHITE valve guide for YAMAHA WR 250 F, YZ 250 F from 2001 to 2013

KIBBLEWHITE offers this valve guide for YAMAHA WR 250 F, YZ 250 F from 2001 to 2013. The guide is a bush pressed into the cylinder head. The valve stem slides in it thousands of times a minute.

Why replace a valve guide?

The benefits:

• Remove the play of the valve in its guide.
• The valve lands right in the centre of its seat: sealing and compression restored.
• A quality guide slides well and lasts, even with titanium valves.

Why choose KIBBLEWHITE?

Kibblewhite guides are C63000 nickel-aluminium bronze: the nickel resists wear, the copper draws heat away from the valve more effectively.

When should you replace the valve guides on your YAMAHA WR 250 F?

The clearance between valve stem and guide is measured with the head off: beyond the manufacturer's limit, guides and seats are redone together with the valves.
