Hey Moses. Hope this message reaches you, as it’s been almost 3 years since the last post. I have a 2003 XR650R uncorked with an XR’s only full exhaust and k&n air filter. I installed a hot cam stage 2 and had issues with it (would randomly die at idle and idle would start to race when engine is warm). I checked valve clearances, engine compression, float height, made sure throttle cables weren’t binding, pilot jetting, checked air cutoff diaphragm for holes, to no avail. I ended up changing it out for a stage 1 hotcam, and the stalling issues are gone. The idle is still a little erratic, it is much better than before. Any idea what could have caused this? Also, do you think my jetting is correct as my last XR650R felt a bit more torquey in comparison. My previous XR had stock cam, full fmf exhaust, 175 main, stock needle on 3rd clip, and 68s pilot. My current bike has stage 1 hot cam, xrs only full exhaust, 185 main, competition b53e needle on 3rd clip, and 68s pilot. I’m at sea level by the way. I’ve searched the Internet far and wide for answers, and it seems like you’re very knowledgeable on this bike. If you could provide your input I’d greatly appreciate it. Thanks
