Has anyone had bad settings from the factory with their tps on the 250sxf? My bike seems to run great but I've never checked it and have been considering on buying a tps tool. Any numbers that seem to be working good? I know each motor can be different just looking for round about ideas

OK thank you. Even though it seems to run great it'd be worth buying to check it out. Do you know if modding the bike could require a change to the tps?

On the new KTM you cannot check the TPS with the bike running , idle needs to be turned all the way down to get an accurate reading

OK I just checked my tps setting and it was set at .49 from the factory, surprisingly it seemed to run good. I set it at. 59 and I'll see how it does

Yes, with your idol backed all the way out . on the old throttle bodies 11 + 12 you don't need to worry about the idle

So I need to back the idle out all the way to get an accurate reading? All I did was plug it in and hit the start button to awaken the electronics and adjusted it from there....will I get a different reading by backing out the idel?

Is this with the bike not running? What difference does it make by moving it or not if the bike isn't running?

Not running of course (it will not run anyway with idle closed). Just hit the starter and it should read 0,40v. After you set the idle back to your level (I run it at 1900 and not recommended 2300rpm) the voltage will go up... I get 0,54v at 1900rpm and 0,58 at 2300 rpm...

OK thank u, I guess that is why people would get a higher rating if they didn't adjust the idle? Thanks again
