1999 Yamaha WR 400 valve clearance - 2011 Yamaha WR450F

SOURCE: clearance for inlet and exhaust valve adjustment

Hi there,

Not sure about clearance levels, but can tell you there is no English manual for the XJR 400 - only Japanese. Try the XJR owners club. It's full of troubleshooting questions answered in the forums.

Hope this helped

Danger :)

SOURCE: did yamaha make a wr 400 in 2004?

I think you will find that the WR426 was last made in 2002. From that point forward it was WR250 and WR450 in the manufacturing line.
