I was actually going to mention him. One his moor before the stroker, he tried a larger carb, 34ish and lost something like 7 or 8 horse than with the smaller carbs. I'm sure many will disagree, but big cabrs don't work well with all motors, I should actuall have something more along the line of a 33-35mm and went with the 30mm to keep it snappy off idle. Mine is far from the fastest bike around, but I have never ridden one that's smoother, even with top end pipes.
