The Rmax is 3200 I think someone posted.Service Manual for my X2.
Valve Inspection 3K miles.

The Rmax is practically the same engine, so I'd say 3K miles also.
I'm slightly over 3K miles, so I'll be getting into the valves soon.
Glancing at the Service Manual, it appears that we have similar design to Tappets that are in some cars. Most of this type of design are interference engines, so I'm now wondering if are motors are of this interference type?
My Honda truck valve adjustment is just like my buddies Honda ATV. Wrench, screwdriver and feeler gauge, it's that easy.
My wife's car has tappets, which is a interference engine and requires several mic/feeler readings then replacing the correct tappet to meet spec.
Now you guys got me curious, so I'll have to do more digging....lol.
