Well I put on a set of true duals and a Cobra FI2000R controller. Took it out and man did it ever back fire on decelerating. So I did the little stuff the Mable in the hose trick. That stopped the back firing 100%. Then I took off the Idle Solenoids but the bike when started up had a very high idle and would never drop off. So I put the solenoids back on it to get my low idle back. Is there something special that has to be done if these are taken off? Do I need to plug the two hose nipples on the backup plate or something? Has anyone else removed them and how did you do it to get it to run good afterwards?
