Just a quick note:
The wiring instructions for this tool / adapter as printed in the MK2 Service Manual are wrong. Actually - they're sort of backwards... except in the Periodic Maintenance section where they got it right :)

The RED and WHITE adapter leads are + and - on your meter. This is described correctly in the Periodic Maintenance section for Throttle Sensor OUTPUT VOLTAGE (section 2-18):


The connections info as listed in the Service Manual section 3-40 is backwards.

The INPUT VOLTAGE leads are BLACK and WHITE, and the OUTPUT VOLTAGE leads are RED and WHITE. They got it backwards here:

 Thanks for that, Tim. What got you into it in the first place?

My first year of riding the Versys was plagued by very rough throttle action, especially at low RPM's.

I order the adapter cable a year ago and discovered my sensor position was below spec, essentially creating a very lean fuel mixture.

After experiencing fairly poor fuel economy on a recent 2000 mile ride to Phoenix and back (about 40mpg) I decided to recheck the sensor position this morning. It was fine but I noticed the discrepancy in the service manual after doubting my meter's accuracy.  :006:

I attribute the poor fuel economy to high speed riding with a very heavy load.

Created this post with the google-friendly subject in the hopes of saving someone else a headache in the future.

 Interesting. I've not heard of North American bikes having severe fuelling problems.

 My Mk2 with an oversize windshield gets a litre worse fuel consumption than the Mk1 with a smaller windshield per fill up. Given the mule-like role to which you subject your bike I'm not surprised at your poor fuel consumption. Couple of straight roads between the PNW and Phoenix too.  :008: :008: .
  A V1K would make a great pack horse.  Almost the same mpg as the 650, more space, 21 l tank, would feel the load much less, and very little higher than the 650. But even more pavement oriented.
 Frankly, it was all I could do not to call the SPCV on you when I saw your bike last year  :008: .
