http://www.motorcycleproject.com/motorcycle/text/cows-clear.html Valve clearance is to cool the valve. Excessive valve clearance with a high lift cam is so the valve sits longer with a fatter clearance is the same as cooling a slow lifting cam with a tight clearance. So, all that you read is if Nixon is correct or is the time to cool the valve the clearance. It is not about hammering the valve train is that high lift is a given is ruin the stock production flow is now more radical. But to cool the valve as per clearance is I believe is for cooling, not what Nixon describes.

http://www.motorcycleproject.com/motorcycle/text/cows-offset.html Once again, you have to follow your common sense if you have to listen to those that cry "Lean" on a mod to the 14 is like the same fallacy or 1/2Truth. If we did not offset the piston pin, the crank would come around and stop at TDC or BDC on the stop of both those 180°'s. The point is: You could reverse the rods and run the engine backwards = Is for the offset. That is the basic reason for the offset; not what Nixon describes is I need to talk to that guy about his info.

And you wonder why I do not listen to too many tuners is read their abstract is point out a flaw in the theory. I am not about to be snowed is to snow you with what I know. I know I have caught Nixon is 2 flubs. Dare I read more and find more fallacy is in the 1/2Truth? I need to back up every sentence I type so you walk the common sense is someone mentions, 'lean'... You want to keep asking so they fill in the blanks is trip them up. Watch how they wheezill out of that (theory they made up) is sick to my stomach I am not an, M-M-My-My/Y-Yo-Yo-Tech gad-chew-it is more a shade tree me can nick, (those 1/2Truth theories all up a tre = Bark'Bark!).
