No clue what the heck happened? I just came back from Kennedy Meadows and re-jetted my bike back to 68S and 175 main. The bike was running fine for about an hour and then we had to get on the freeway and once I got into the higher gears it bogged and died. I've heard the pilot jet is for low gears/low speeds and the main is for high gears/high speeds so maybe the main jet is blocked w/ dirt or something? It had problems starting back up too. wierd. Any ideas?
