2010 rzr4 chatter on take off

I have a 2010 RZR4 800
the other day I was going down a sandy trail. there was a 2 WD ranger with 2 kids about 16 year old stuck. I helped tow them out. little bit more down the trail they got stuck again. this time I couldn’t get them out. I know the rzr is not a good machine for that but I felt bad leaving them there.

now when I take off it shutters a little but only just taking off. soon as I get rolling its fine. I changed the belt and it did it a little less but still did it. going down the trail is fine, stopping is fine. its only when I come to a complete stop and start to take off again. any ideas to what It might be? I’m new to the side by side’s. could it be a clutch issue? no grinding or clanking from the motor at all. any help would be greatly appreciated.

RZR4 conversion questions

I recently inherited a RZR4 that had a z1turbo conversion put into. The enginge is not running and we are in the process of taking it out and figureing out why. My question is if it is blown and requires a new motor can you put in the 1000 in place of the original 800 that was in the rzr or do they not match up? Trying to figure what my swap options are if the Z1 is toast. Thanks for the info

Starting hard 2014 800 4

Last cpl times I have went out to start it it rolls over like 5 or 6 times. It has 2000 miles on it all stock. Last night while I was driving I stopped to watch some deer and lights flickered once. While I was sitting there I wanted to see where clutch engaged so I rev’d up slowly and when I let off it stalled. When I left that spot at idle was 11.7volts. It took bought 100-200 feet to pick up to 12.7 v and that’s where it ran. So my question is it fuel pump or regulator? Can’t see it being fuel since the lights flickered when I was sitting at a idle. Just looking for a lil input

’11 RZR4 800, Intermittent Stalling

Random stalling. It’ll be running great and all of a sudden RPM’s go down and may or may not stall. We have a tuner and will unconnect and reconnect, to reset, and it may or may not run well. We have stopped and turned ignition off for a few minutes. Sometimes it’ll run the rest of the day ok, other times…not. Have been running 92 Non-Ethanol gas. It’ll happen when running a short time or for a long time. Have checked connections, fuel pump…any ideas? Maybe fuel pump relay?
