'92 907ie ... high idle when warm
Posted: Thu May 30, 2019 5:25 am
Hello ,
My recently 'awoken' 907 is doing great and over all I am more than pleased .
One thing is a bit baffling however --- at cold start-up she will fast idle at about 1,400 until the "choke" is removed , then it drops to about 1,150 and all is well . When the bike is being ridden normally , the temp is about 150 ish and at a stop , it will idle at 1,150 to 1,200 .
I have a very long driveway that is gravel and sloped and we take our time and travel slowly . When leaving the house and going downhill ... when we reach the road the temp is about 175 or slightly more and the idle will be around 1,600 . When we come home ... going uphill , temp are around 190 to 200 and idle is around 2,000 and the fan will run for maybe 1 minute or so .
It almost seems that the bike is trying to protect itself from overheating by having a high idle . I am likely so far wrong , it's laughable on that one . A complete sync was done and balanced nicely .
It has been 20 years since this bike was used ( please hate me for that , I certainly do !! ) but we sure do not remember any similar behavior . Although , we never saw it get this warm either ???
The fact that it will go back to a normal idle after being ridden has to be a clue of some sort .
As a side note ... this bike was bought new for my wife and she has put almost every mile on it ( 25,000) ... she was present when I started it for the first time about a month ago ... and she cried , as in great big 'ole alligator tears . Yes , these things are special . Soooo grateful to still have it !!
Any idle ideas ?
Thx , JD
