UPDATE; new procedure for tps testing.
this is another approach in diagnosing the Idle Instability Issue.
In order to isolate which of the two parts is the source of trouble on the throttle body i discovered an interesting way to isolate the tps, you unplug it!
the following video shows how to do this and what tools are required, most of us can follow this procedure.
1 if your bike runs better after the tps is disconnected that would be an indication the tps is bad.
2 if it still has the same problem after disconnection it MAY be the iacv.
During the test drive i noticed three things;
1 cold idle is at 1250 rpm.
2 throttle response is " softer " and smooth handling may be required to keep it running on startup.
3 my exhaust vacuum valve did not operate ( think the bike is in a different mode )
It appears ok to drive this way but just to be on the safe side i would not recommend long periods unplugged riding.
What may work for you is giving you the length of cable as shown in the video but leaving it connected, go for a drive and when the idle is acting up stop, disconnect the connector and see what difference it makes, even several times to make sure the method is repeatable.
If success is achieved i suggest making a video showing; difference in rpm, connector disconnected and connected possibly several times.
this can easily be done with the bike running on the side stand.
if this is done correctly it may well lead to a refund or recognition of sorts by the dealer and dispel uncertainty.
This method has been done by several service personnel and documented as such.
Let's hear your experience with this method, it has to be the simplest to date because we really need some feedback from you affected owners.
