XT Valve Clearances
 
HI,

Just bought a Clymer Manuel for the XT (83-89). My bike is from 2001 though... Can I use the manual valve clearances values?

Is it necessary to check valve clearances in the intervals Yamaha recomends?

Thanks and regards

I've checked the valves on an XT600K 3TB of 1991 [22.000 km until stolen] and XTZ660 3YF of 1992 [80.000 km now] on several occasions and it was never necessary to adjust them. Except when I rebuilt the upper engine part @ 50.000 km of course.
So I would say, if you don't hear-em rattling, don't touch-em.

Out of adjustment valves only "rattle" if the clearance is on the lose side - my K100 ticks like a clock if they're loose.

If the clearances are on the tight side however, you may well not know about it, you may only suffer a slight drop in power whilst your valves are held open & possibly being burnt away at the edges.

It's easy enough to check the clearances & easy to adjust as I believe they're screw & locknut tappets on the 600's?

I believe it is an easy task, judging by Clymer's instructions.

Anyone knows if Clymer's values are still the some for my 2001 XT 600 E???

Thanks and regards,

I've not owned an XT600, so cannot answer directly.
