    2003 XR80R Jetting

    Hey guys, first post here. Just picked up an '03 XR80 to go along with my '05 CRF150 and am a bit stumped on the jetting for the carb. It is my first time really tinkering around with a dirtbike and while it seems easy enough, I can't seem to find jets that fit my carburetor. It is the Keihin PC20J carb and I tried bumping up the main jet to a 100 and the pilot to a 40. The ones I ordered which were supposed to fit my carb ended up being slightly too big and it seems to be the only option I can find online. I've read other posts online about people rejetting them, I just don't know which jets they used or where to find them. Any ideas? Thanks.
