Fast Idle Plunger Repair (TDM 900) [ie Cold Start ]

[DenH]

Right side of the engine Den ( sitting on the bike ) squat down and look just under the top frame member above the engine and you will see the idle adjustment tucked away,, you can twiddle it by hand m8,, 1100 to 1200 revs give the throttle a blip after.

Yes I know that one!  It adjusts the normal warm engine idle speed and is set correctly..

 

I was looking to increase the idle revs for a cold start if it can be done as my bike fires but stalls unless I use some throttle.  Even after freeing off the fast idle pin which is now working properly.  Once running the revs build slowly to about 1500, then drop back to 1200 when warmed up.  Only a minor problem but wondered if there was adjustment.

 

I noticed that there is an adjustment screw on the end of the slider (left hand side) where it contacts the pin of the fast idle mechanism and wondered what that did?
