I don't do much WOT riding, there's lots of windy mountain roads around where I live and I seem to live in the 5-8k range most of the time. Last summer I did a trip with some friends that included some superslabbing. Boredom gets the best of you and before you know it you're racing your buddy down a long flat stretch doing 200 km/hr plus. Oops. I noticed on that trip that the bike would hit a certain RPM, somewhere north of 9,000, and just hit the wall and die. Engine falts bigtime, zero power. Kick it up a gear and the power is back on, but same RPMs it hits the wall again. I thought maybe it might be a fuel filter issue, I had just done the 24K service and, uh, skipped the fuel filter. This spring I replaced it, but the same symptoms persist. Any suggestions as to likely culprits? Coil(s)? Ignition modules?
