pvc mod

[John Biccum]

I put the PCV in my KLR when I put the 685 kit in about 25,000 miles ago.  KLR Cary was a passionate advocate of the PCV mod and I deferred to his considerable expertise.  I don't know that the PCV helps with oil consumption.  I do know that I have seen zero oil consumption on the 685 kit, but I don't know that that results from the PCV.  Maybe it results from the new rings and valves?  The KLR did use a small amount of oil for 35,000 miles until the 685 kit went in. What I am almost certain about is that adding the valve DOES NOT HURT.  It very low cost farkle so I don't see any substantial risk.  Why not add one and see?  If it does not help reversing the mod can be done just as inexpensively.

I don't have personal experience with the PVC mod. I've heard reports saying it's the best thing going and also that it didn't work. Good luck making your own decision
