Tuned and Synch'ed
I have a Breva 750 04 on which I have problem with the idel speed.
When it's cold I have no problems att all, the idle rpm are between 1000 - 1100.
But after riding for like 10 minutes and coming to a traffic light for a stop, then the rpm slowly goes up to 2000 and stays there. This repeats for every stop I do when I'm riding the bike.
I have done a synchronization with the help of my Twinmax. But it's not possible to do a perfect synchronization, in that case I get to high rpm at idle also at lower temp. So I have to adjust it a little bit to be unbalanced. The air bypass screws has to be closed also after balancing to get proper idle rpm. TPS is also reset after the synch.
I have done a test after I came home running the bike. I connected the computer and started Guzzidiag to read the engine temp was 98C and the idle 2000 rpm, I tried to disconnect the rod between the throttle houses, but there were no change of the rpm even after that.
So the next thing I did was to remove the oil temp sensor from the RH cylinder head and measuring it at specified temps. This are the results that I got,
At 20C 3,74 Ohm should 3,7 Ohm
At 100C 204 Ohm should be 220 Ohm
Could the result att 100C be the cause for the idle rpm at high temp?
Any suggestions are highly appreciated.
