Will not shift when running

I just got the 400 running and took it out for its first run. The main problem is it will only change gears with the engine off. Just grinding noise while running. It shifts fine with engine off, sloppy but shifts. Is the problem with the shifter or the secondary drive? or are the shifter forks gone? Plenty of power in high and will stay still at idle
