Wow, you guys are sensitive. No jap bikes don't break all the rules. Merely
mentioned them as they have ports that are fairly lazy in velocity at lower
revs, with high overlap. This I stated (albeit not explicity enough) as an
example of something that often responds very well to open valve injection.


If you take a look at the new GP bikes that will be out and some of the
other classes, you will see a lot of FI bikes. I agree that carbs can often
be very good as many of the bike CV carbs are. 

So I take it that you guys are basically of the opinion that it there would
never be a reason to inject on an open valve? That's fine. That's your
opinion. I still disagree. That's fine too.
