Guys,
I have searched and read a few posts regarding this high idle problem (over 2000 rpm) and I may have found a cause for it.
I have recently had trouble with my oil pressure sensor and through diagnosis and a number of attempted fixes, I finally got a new sensor in. To do this I needed to remove the air box and over the last two weeks it has been removed 4 or five times.
Anyway, when I got the sensor in last night and the bike reassembled I tested the bike and it had a high idle, around 2200 rpm. Its never done this before. Having swung a few spanners around between the cylinders getting the oil sensor in, I thought I might have dislodged or altered the throttle cabling so I took the bloody air box off again and the cables were perfect. Also note that the breather tube that connects under the air box was fitted correctly on each occasion.
Then I started looking again at the air box and the tricky way the trumpets between the air box and throttle bodies connect. I figured if there was an air leak there due to it being poorly fitted then the idle would be affected. So this time when I put the air box in I took care to fit the trumpets fully and firmly, and hey presto, no high idle.
If you are having a high idle problem (or even an intermittent high idle) I would be looking at the trumpets to see if you have a perfect fit.
