Just got my 511 SMR and put about 200 km on it over the weekend. Two things I noticed: The slow idle seems a bit fast. Is there a way I can adjust that manually? When the bike gets hot, I noticed that when the throttle is rolled off, the engine drops down to a kind of fast idle for 3 or 4 seconds before dropping back to its proper slow idle. Anyone know what that is about or how to cure it? It isn't a huge problem but it would be nice to get a proper slow idle when thats what I want.
there is a big brass screw on the side of the EFI that controls idle. As for the hanging idle that is a design feature on the EFI map for this bike making it not have that horrific "slam the rear brake" feeling 4 strokes have when chopping the throttle. I love that feature, makes it feel more 2 stroke like and free flowing.
And this is what I love about the internet. Answers to every question from an expert in the field. Thanks, I found the idle adjustment, I will try and adjust it later. I have only been on the bike for a day so but I don't remember the hanging idle all the time. It only seemed to be there when the bike was hot and during slower speed maneuvers. Is there a way to adjust it? I find it goes on for too long. I'd be happy with a second at most. While I have you, the fan doesn't seem to be kicking in when the bike is hot. It is getting hot enough to puke out a small amount of coolant. I tried to spin the fan by hand but it seems a bit stiff. It does turn but not as freely as I would have expected. I suspect the coolant may be slightly over full from the factory. The oil certainly is.
I also have had this issue with the hanging idle. It lasts way way too long, in fact I can come to a stop and the fast idle will just stay on indefinitely even if I chop the throttle. I know this can't be right. Does anyone have additional suggestions on the mapping adjustment or idle mix adjustment to fix this issue? '11 TXC511 JD Tuner at suggested settings Thanks.
