I can't argue about the timing but I have another theory. I have the bike cutting out in first and second all the time before hitting the limiter and maybe third (can't rememeber about 3rd) but only when I start flat out hard(Ok I'm racing someone from a stand still). I have cams and big bore and I know I'm sucking some fuel. It's worse with Truxton needles. Additionally my fuel consumption has increased with Truxtons. I was getting over 140 before hitting reserve and now it's 130 or less. Don't get me wrong, the bike is strong and I have learned how far I can push it before the cut outs but it's not right. Consider what Bellacorse says about the stock pet cocks flowing 30 oz of fuel per minute as opposed to 90 for the Pingle. It works out to half ounce of fuel per second for 2 fuel bowls IF your 2 screens are perfect. That isn't a whole lot of fuel when you consider how long it takes to run through first gear. I have to figure it's 3 seconds or less, maybe 4. With 4 seconds it's 1 ounce per bowl if bellacorse is right. Maybe it's more than 4 but bottom line it doesn't seem like enough fuel for those of us that have modified for max performance. I have had my measured shots of Tequila and I just don't think it's enough.
