I've had my F.A.S.T. Drag motor together around 3 years now, was at the dirt drags yesterday and it would pop out of gear. I got about 20 cleAn passes out of it and then it started. It will engage fine and once I leave the line it'll pop out in the top of first or second. Not every time but 70% just wondering if it could be forks bent or if Tranny is shot? Tranny is a N down 1-5 dunable override that I got through Dave. It's been a great tranny.
