To many things to look at but here goes..... First off never had a lick of problem with the bike! Today 12/29/03 went for a little winter ride..... (00 Busa) with very minor mods. Exhaust, K&N filter, & nothing else.... The bike ran great the first forty minutes then out of no where it dies! Lasted about 4-5 seconds, I was coasting around 40 MPH glanced down and saw the check engine light was on. Then faster than you can say "Theres no place like home" it was up and running again. Did this one more time before I made it home. I plan on checking the TO sensor and ECU.... any other suggestions or similar experiences with your bike? Grounded in Ks.... One last thing I did check the engine kill switch for a lose connection. This wasn't the problem.
