RTV500 modifications

[Luke.Tyndall]

Hi, I’m in New Zealand and I have a 2019 Kubota rtv500. I want to modify it as it has very poor low speed torque. I am considering the 3 modifications below and wanted some advice on if I’m doing the right thing for low speed torque without straining the drive chain.
- new air intake filter
- clutch kit
- new efi tuner
If this is a good idea what brands would be recommended.
Thanks,
Luke

I am not very familiar with the rtv 500 but I'll try. Since this is a gasoline engine and two cyl 15 hp my guess that it doesn't have much low end tourqe anyway. As in its diesel brothers the linkage adjustment is critical to matching engine rpm torque to the hydrostatic transmission so i would spec that out first. I doubt an air cleaner change would make a difference unless you port the head. Now the tuner may be a different story because i know the diesels are de tuned to fit cafe standards. You might just need to advance the throttle until you are getting the torque range. What is your attitude? That makes a difference
