I don't need to get the plate before Mid-O. I just went to the dyno and don't want to change anything. I do still want one. I alo want a another block off plate, 4 flanges, 2 long megaphones, and 1 short one for the fall.
The 160 chamber is different enough that those couldn't be used on a 175 I don't think. And with that dome there are going to be a lot of people that smash their piston into the spark plug electrode unless they machine clearance for it.
I sure hope they aren't using the same forging I am...cause there aren't a whole lot of them left.
PS. Let me know which flanges you need. The head side design, or the 24mm Keihin design.
