Im from the UK and ive just ordered the bigger 38mm carb off of a ktm 125 and the necj suzuki needle for my 2015 sx250, can anyone recommend some jets? I ride at around 500ft above sea level, and the temperatures from 50-70 fahrenheit. Thanks

You're missing the 38mm carb. She won't rip until you do that.

I got a 15 tc250 with a full bills and a 38mm carb....she rips!

May want to try cruising the thumpertalk and ktmtalk sights for some more in depth KTM specifics on any other stuff too.

My son rode gameovers 250 and had me
swap carbs off his 150. We are currently at 42 pilot and 175 main in central Fl. My only issue is I kept the 150 float in it. I'm not 100% certain but I think the 250 float on the 36mm carb allows more fuel in the bowl (same float just different float height). Basically richer than the 150 float setting. If you are swapping carbs make sure you look at float height. Thanks Gameover for letting him take your bike for a few laps! Hope you got your suspension issues fixed!

Hey hey, not a problem. I guess your son loves how the bike pulls now?

I originally had ZipTy Racing do my suspension....after riding your son's bike I tried to get some support from ZipTy Racing with no success. I got frustrated with them and went ahead and sent it off to Factory Connection....

So after spending about $650 having ZipTy Racing revalve my suspension Factory Connection quoted me around $950 to revalve it again due to parts that were hacked and need to be replaced.

Ohh boy.

Yes he loves it for sure. Let me know how FC does on your suspension. By far the best out of the box suspension we have used. We have made only slight adjustments since getting it back. Just make sure you are up front with them about riding type and skill level and you should be very pleased.

I live around 0-500 ft elevation but a bit hotter in the 80-100 degree range. During the winter with 50-70 degree temps
I had good luck with the NECW on third clip also. The Necj was a bit rich when I bumped it down to the fourth clip and the NECW seemed to ridge the gap well. Also running 40 pilot and. 170-172 main
