G'day all, Got an odd thing happening for the last few hundred kilometers with my late 2006 990 Advventure. Idles fine, revs fine in neutral, but when riding it sometimes wants to hold the revs up higher, 3/3500ish. Wants to keep driving the bike with the throttle closed, and will very slowly come down as you coast along back to idle (just not as quick as it would usually when shutting off the throttle), but it will drop straight back to idle when the clutch is pulled in. Pretty annoying when coming into corners and stuff... The throttle cables all adjusted OK, action is smooth as with G2 +400 cam, new air filter, clean fuel filter etc. Got me thinking the TPS may be out of spec/ adjustment. Went over it as per the manual, here's what I found.- Manual spec says- Test black and yellow wires from TPS with multimeter, ignition on, should get 0.5V- 0.6V throttle closed, 3.6V-3.7V with throttle open. Here's what I got- front TPS throttle closed = 0.62V open = 3.90V rear TPS throttle closed = 1.03V open = 1.03V Hmm....front's a tiny bit out, not worth adjusting just yet. EDIT- Upon closer inspection, the rear controls the secondary throttle butterflies, however should the reading be the same as the front (there's nothing in the manual mentioning the rear TPS adjustment), and could this be causing the surge/ higher revs with a closed throttle? Anyone else came across this before? Cheers, Dan.
