Bike worked perfectly for a very aggressive ride on Thursday in Moab. However, on Sunday it would bog down immediately after a G-out:
Ripping along at wide open throttle, fuel delivery fine. Hit a G-out and (1) low fuel light would come on, bike out bog like it was running out of fuel, sputter a little bit, then sort itself and run fine until the next G. I removed the gas cap vent hose / filter, didn’t help.
Rather than try to sort it on the trail at the start of another hard ride, I decided I had had 4 great days of riding, flipped it, rode back to camp to jump on the 790 and meet the B crew riding to Chicken Corners.
Wound it out in the way back, 90+mph, ran fine.
My thinking is to replace / address all things fuel delivery, as the bike has just under 500hrs and 12.6k miles: fuel filter, fuel pump, install an additional inline fuel filter. Might as well replace the fuel injector, new spark plug and check the valves while I’m in there.
Am I missing anything? It was weird, acting like a carbureted bike when the tank isn’t venting properly. And it was literally the first time I’ve ever seen the low fuel light
