okay, time to tune the 2003 XR100R carbs
problem: popping under decel, feels "lean" in the midrange, and won't idle for > 5-10 seconds
history: bought the bike used, came with an FMF pipe, wouldn't idle. I pulled the carb, blew out the pilot jet, and buttoned it back together. It idles, but stalls after 5-10 seconds.
cranking the idle speed (which raises the slide) causes the engine to race too much; so I lowered it enough where it uses the pilot circuit, but once you get there, it still stalls after 5-10 seconds
stock jetting: 35pilot, 98 main
called Honda, they told me to call FMF. Called FMF, and they said it should be stock.
I pulled out the 35 pilot again, and honestly, it looks fine. I found a local shop with a 38 pilot, I screwed that in, and I'm going to try it out tonight!
I also dropped the clip on the needle by 1 notch...needle sits a smidge higher now.
