Cam chain specs for 1998 WR400?

3 posts in this topic

I looked it up in the pro-x catalog and for the YZ/WR400/426 the pro-x part #31.2419 crosses over to 92RH2010 -120M Borg Warner

Both Yamaha and Pro-X chains are sourced from Borg-Warner Japan, and as far as I can determine, there's no difference between the two.
