2008 sportsman runs… kinda

Hey guys new here, a little background for you. I have sportsman 500 that’s been sitting for 5 years. before I put it up I drained all fuel and put about 10cc of oil on the piston so it wouldn’t freeze up. I needed to replace the stator pick up and starter. All got wet. So as a safe measure I cleaned the fuel tank, carb, and got a new vacuum pump, new plug as well. Got the new stator in found out the square stock on the fly wheel was broke and replaced that and here’s where it gets interesting. So if you turn the bike key off then back on and start it, it will fire up for like a second or two. And I try to crank it up again, it turns over but won’t even fire with either. So again key off then back to the on position fires up then dies. Does anyone know what it could be? I was thinking maybe the ignition module? Idk I’ve been pulling hair thinking about it. I just read on here there is a Saftey in the throttle controller on the the right handle bar and if the contacts are not touching it could shut off like that! Any help would be appreciated
Ps I’m a diesel mechanic so I’m pretty savvy in this field just a different machine

2005 800 sportsman rear prop shaft question

Anyone else with this year 800 sportsman ever change there rear prop shaft u joints and yoke? I twisted a u joint so banged the role pin out (front yoke of rear drive shaft) than took the broken u joint out than tried everything to slid the rear yoke off that’s connected to my rear diff shaft. It has role pin hole on the yoke but there’s no pin on the diffs drive shaft I just see splines??? Am I missing something or what! No amount of prying or penetrating oil does anything! So frustrating
