I was riding my 426 at the track this afternoon. Something major happened. I was going through a small whop section and the bike stalled. It died kind of weird while I was in 3rd gear or so and one the gas and it just died. I stopped and after a few of the ritual kicks it fired up. Ran for another 30 minutes or so just fine. Was riding in 4th and on the gas and it did the exact same thing. It almost threw me over the bars it happened so fast. It was running fine then suddenly just felt like it lost all pull and the engine stopped. It was not abrupt, but it did stop pretty quickly. This time it did not fire back up at all. I know the ritual starting procedure and she usually starts up 1st or 2nd kick. It feels like it is not going all the way through the normal stroke. I can use the decomp lever and it will go through so it is not locked up. Please help. I am supposed to race a hare scramble this weekend but it looks like that may be a lost cause. Thanks for any advice or a starting point.
