I'm having a similar issue with my Axis 500. It seems to bog down and struggle, particularly on inclines/hills (see video). Frustratingly, it also only happens intermittently, more often when the machine has been running for a while (I use it for farm work only). So far I have:
Replaced fuel filter
Replaced fuel injector
Replaced MAP sensor (reset ECU after)
Replaced spark plug
Verified air filter is clean
Verified no obstructions in exhaust
I only run it on 91+ gas and put a can of seafoam through it to no avail
I did previously have an issue with a failed one-way bearing, but this particular issue predates that failure. I replaced the one-way bearing a few months ago and inspected the wet clutch, primary/secondary clutches and belt while I was in there-didn't see anything of concern. Where do I go from here?
