this is just my theory
I have some very simple and cheap ways to test this

Interesting and I can go with that, but how come so many do so many miles without this problem and by many I mean thousands, do they have a different head casting for different models?

Moto fathead is having both inlets done, guides, seat and valves. It seems to have been dusted before Chopper got it, the valve was worn we adjusted but it was on the way out and has continued to wear at a rapid rate, exhaust valves and clearnces are fine, which is a normal thing when dust has been involved

TB the Throttle use has a lot to do with what Bull is onto and we all use that different:)

Read what you wrote Dave, makes less sense than you normally do and thats saying something!
