DIY video increase power on a Kioti CK2610, CK2620 and CX2510 tractors - Turning the fuel up

Thanks for the reply 5030,
So far I've put about 70hrs on my tractor since turning the fuel up without any issues. The pyrometer was more of a gauge to measure how much it increased in temps from stock. The stress test of going up the hill was as hard as I've ever used it. At the top of the hill the hydro bypass is being hit and that grade of hill I would never normally go up in high. Under normal usage no temp change, moderate load is +100F, and under prolonged heavy load is +150F. I can say I haven't noticed a difference in fuel usage but it's using more.

After 70hrs I can say that normal usage of digging and moving dirt I am super happy I turned the fuel up. I'm currently grading/leveling a pad for a metal building

Just keep in mind always that where you have the 'stinger' installed isn't the actual combustion chamber temperature at all but I'd add at laest 100 degrees to be the actual combustion chamber temp and aluminium pistons (which you have) don't like chamber temps above 1200 degrees prolonged. Bad things start happening to them aboive 1200 degrees (f).

On my M's the engines were built internally to deal with the excessive chamber pressures the turbochargers make so it was no worry on my part.

What I find interesting is how Kioti got around the emissions mandate on their smaller units like you have and I bet Kubota does the same thing and probaly Deere as well.

My tractors are well above that threshold for EPA mandated emission controls but being pre 4 none of that applies anyway and why I would never consider a new tractor because my requirements in power will always be at the expense of pollution controls and I have no desire to own ANY tractor with that. If I remember correctly (could be wrong), that any tractor over 100 pto also had DEF injection as well. Just something elsr to fail.

Mechanical pumps are all easy to turn up, different pumps in different ways but I left that to my dealer to do as they have the dyno to monitor the increase and set them accirdingly.
