OK, so we've spent way too much money on this bike for Baja and something took a dump on us last weekend. We've spent hours trying to trace it out with NO success. Hopefully someone here has some insight. We're kinda new to XR650s. Engine releted Mods: Ricky Stator 250 watt stator w/ voltage regulator. Honda Power-up kit White Bros E2 pipe 172 Main Jet, 65 Pilot Jet, stock needle position EVERYTHING else stock Bike was running GREAT with all the above mods. 200 miles or so with all the mods in place. THEN... las weekend it started running rough. REALLY Hard starting (but it will start sometimes). Really crappy sounding engine, popping and backfiring, won't idle. We can keep it running, although very poor. Bad rattly, loud, nasty. It's not an intermittent, it's done nothing but run bad since this started. At first we were thinking electrical, but we have looked at every wire, and they're all connected well as far as we can see. Then we thought fuel, but we've cleaned the carb twice and it has run fine with the jetting it has. Could it be a stator failing?? I'm frustrated!!
