We have the valves, springs and copper rings at our website, www.hendersonmotorcycleparts.com .|

After spotting the broken intake valve spring, I found something else amiss - intake valve #4 is 1/8" shorter than the other three.
Yes, the others are 3-1/2" tall, but this one is only 3-3/8. All valves are marked Thompson W.B. Did someone years ago just use a wrong valve? Could there be a reason for this? My only thought on this would be the guide is oversize and the short valve was available with an oversize stem? Just a conjecture before I dig further.
Another question. The intake manifold has KJ-1722 stamped on the top of the carb horn. On the bottom is a large "X". Does everyone have an X on theirs? Does the X have any significance?
