Valve clearance OVER range?

Recommended Posts

I bought an almost new 2015 KX250F. Started first kick when I bought it. After a couple rides, idle started to hang, it won't idle without choke and hard start. I suspected valves need shimmed. Pulled the top and did my best to check clearances.

The intake clearances had tightened up to under spec, but the exhaust clearances were OVER spec. I don't know if this is normal or possible or previous owned jacked with it or I measured it wrong.

Intake range is .007 - .009 mine measured .004

Exhaust range is .004 - .006 mine measured .007

 

Anyone heard over clearances being OVER spec range? I'm new to the 4 strokes.

You're backwards. Theres no way, on any bike, that the ex spec is tighter than the IN spec. Ex is the flame thrower. Blowing flames and heat. The intake opens its mouth to the clouds around you, not fire. Metal expands with heat. 

These bikes have been .004-.006 Intake and .007-.009 Exhaust since they were created, before one was ever built.

Correct me if Im wrong Face

thats right notorious.    Perhaps you mixed them up when you wrote them down.   Or you were not at true TDC.   Id double check.
