All

Took bike out couple of weeks ago and was getting a bog in corners and when snapping the throttle on. apon reading abit more through here seen someone with similar issue where pilot was to lean. I have since changed to 37.5 pilot and 520 main. I took bike out again on the weekend and all i can say is...

Yer following specs from page 1. And i have put. 30 in the pilot for the notch and it is also between 30-40 degrees most of the time when im riding atm. Running unleaded 98 with motorex 2t oil @40:1

Have a 2020 ktm 125. Ran great first couple months from new. Then i started chasing my tail with jets. And nobody could point me in the right direction. Somedays i could get it close but always had that 1/4 throttle bog and rich pilot that i couldnt shake. I couldnt get a slide as they are on back order...
