Valve Clearance Question

[Jim Moore]

I'm checking the valves on my Agility 125. Intake is good. The exhaust has essentially no clearance at all! before I make the adjustment I want to make sure. I check the intake and exhaust with the engine at the same spot, right? I don't rotate 360 to check the exhaust, do I? In my mind it makes sense to do them both at the same time, but I'm a little surprised by the tight exhaust valve and I want to make sure. I've worked on a bunch of twins where you have to rotate the engine 360 to check the other cylinder, but I don't thinkk that applies here.

Thanks in advance,

  When in doubt, and as a good double check observe the cam lobe and verify the follower is making contact on the base circle portion of the cam lobe. The base circle makes up a good portion of the lobe, and pointing the nose (point of maximum lift) directly away from the follower contact point will ensure you are adjusting the valve clearance on the base circle. ( Cant go wrong)
