Hey all, I just bought a '13 KTM 250sx and noticed the carb has been 'oval bored' by cycle playgound to 36mm x 38mm. My question is what effect does this have on jetting? I pulled the carb and its setup as follows: 40 pilot 168 Main NOZG needle 4th clip Can I rely on the jetting chart in the manual or am i on my own now? Just ran the bike this week at 4500 - 5500 feet and 80 - 90 degrees. Bike seemed to run great but had trouble idling when warm and I noticed after an hour the plug seems majorly fouled (see photo) Any advice would be greatly appreciated! Thanks!
