Hi all . Recently purchased a '99 X1 . Bike runs fine except for ' holding on ' to the revs at 2000rpm for a couple of seconds before they drop as normal . Any ideas / info appreciated . |

Hi Rolo Thought you had given up on Buells after selling your tidy S1. Had this problem on a couple of XB,s after resetting the TPS. Try backing off the throttle stop screw just a smidge that might cure it, or could be something else ie:air leak on the intake,but try that first. I,m sure someone else on here will come back with a better suggestion, Good luck :

had same on my uly then read this viewtopic.php?f=7&t=14418 and changed deceleration correction % and region but first be critical of what you want ? how much deceleration /engine braking and when you want the fuel to start flowing again and resume normal engine running. had about 3 goes at adjusting and settled on this adjusted mine from 96% to 75% deceleration correction and regions changed from old new 1600 0 1450 0 1650 19 1500 19 2950 19 2950 19 3000 23 3500 23 |

I never heard before about X1 having this problem, but about many XB. I would check for an intake leak first, then do a TPS reset. If the engine still hangs at 2000 rpm it might help to reduce spark advance significantly - about half the original value - in that column (cells marked by a red square): Attachment:
