I you'd like to try the injector, the part # is 28160355. On ebay they are about $10-$20. Easy swap out. But, with 300 on it, I'd bet on the timing chain. Easy check; two small bolts to pull out the tensioner.....

An injector is about $12, and yes, that is a possibility. As this UTV had only 200 hrs, that's what I did first, and quickly found how wrong that knee-jerk solution was. If that new injector does not help, you might suggest that they pull out the chain tensioner to see if there is any tension on the chain. If not, that's the problem.... If so, hope there's a warranty in effect, as the engine has to come out for replacement.

Thinking of the one here that I just took apart w/200 hrs on it, I expect the timing chain is shot. As the chain wears, it retards cam timing, and starts to slap -tighten/loosen-as the engine spins, so the valves open/close at the wrong times. Finally, cam timing is so far off that there's little or no compression, and/or the chain jumps a tooth or two.....so the engine fires someplace other that just before TDC.. Fairly easy to get to the timing chain tensioner, pull it out to see if it is at full extension (no tension on chain). If so, the chain is toast.....

I know this is a old thread; but how many hours were on this UTV? I have one here with only 200 hours, and the timing chain is shot! Thanks....
