Doin' the Snoopy Happy Dance!
Finally, the '15 V650 is running so sweet and smooth, better than it ever did even on the test ride at the dealer 2 yrs ago. Earlier this summer it suddenly started running really poorly. Obviously a mixture problem, replaced the O2 sensor to no avail, used an O2 replacement plug to some improvement.
Discovered a split vacuum line to the Intake Air Pressure Sensor. For some odd reason the sensor doesn't sit on the intake, but at the end of 12" of vacuum line. That line had a hidden split which must have been there from the original assembly, but got bad enough this summer to make the bike unrideable.
I thought all of you must never have ridden an in-line 4 cylinder bike because you've all been praising how smooth the gen 3 motor is, especially compared to the previous generation Versys.
Truly I have been considering replacing the V with either a Tiger 800 or something with an inline 4 cylinder engine in order to get away from the vibrations.
The bike had a roughness between 2800-3200 rpm since new. When warmed up it would stumble in that range. And a bit of a vibration at about 5000 rpm on the highway, tickling the prostate uncomfortably (but the ladies might have enjoyed that feature). Now all that vibration is gone.
I'm doing the Happy Dance today!
