Might have bent push rod?!! 2011 S

Rode at Hidden Falls last weekend. RZR started making a loud grinding noise like I was dragging beer cans. When I pulled into camp, I put it in park, killed it and it kept trying to run like it was dieseling for a few seconds. Then it grunted, died and went poof and black smoke boiled out from under the bed. We pushed into the trailer and came home. When I pulled the cover I found the starter wire was burnt and starter was fried, froze up. I had a new starter so I replaced starter, wire and solenoid. When I crunk it there was a definite tapping from the head and it wouldnt idle but maybe 20 seconds and was like something was choking it down. The air filter is clean. Throttlebody is clean, never had any dirt in it. The oil is clean. The starter man was thinking the drive had hung up explaining the grinding noise, but I’m wondering if it tried to jump time and bent a rod. Or is it possible the oil pump is not working? timing belt or gear? I havent read much on the motor, never had any motor problems so I’m gonna have to learn real quick. I’m gonna pull the pipe and valve cover tomorrow. Any help would sure be appreciated.

800s belt/clutch problems

I started another post about my 800s cutting out a full throttle around 5800rpm and 30-35mph. Another member suggested I make a new post with clutch or belt help in the title, so here it is.

Quick run down of what I have checked.
Air filter clean
Battery terminals tight
Old gas pumped out and new put back
Checked fuel pressure and it was at 40, another member said it should be 60?
New plugs.
I’ve ordered new plug wires and belt.
Once I tightened the battery terminals down it got a little better.

800s problems

I have a 2011 RZR 800s 90 hours and 989mikes. At wipe open throttle around 30 mph my machine starts to cut out on me. If I ease into it, it performs normal. So heres what I’ve done so far:
Cleaned the air filter.
Drained all the old gas and put new ethanol free gas.
Check fuel pressure, getting 40psi
Replaced the plugs even though they looked fine.
It still does it? I ordered new plug wires to try next. But is there anything else that can be going on?

Need help with this clutch

Just recently bought an EPI mudder clutch for my 1000. After finishing the primary clutch there were two blue washers left on the compression tool. Not sure where they go. I don’t believe they are shims because if they were on the backside there would be nothing to space it. I’ve attached a pic. Any help as to where they go would be great.
