solid roller lash

Every cam..Ever engine is gong to be different..and every person is going to check it is different...

If the engine/cam is new...I would check it after a couple of races to see if anything has moved...I would really look for adjusters backing off...

After checking things regularly ...you will get a feel for how often you need to check the lash...

I have gone a full season and never had to adjust the valves..I checked them..but nothing changed...but i would still take the valve covers all and look for anything loose.
