OK - here's a couple of points.Hey Guys,
My bike is 100% stock, only 2200KM on the clock and I am using 87 Octane fuel. Today when I was coming home from work, there was an incredible amount of traffic. And when I mean incredible, its stop and go for miles in every direction, the worst you could possibly imagine. I tried finding an alternate route home and of course, end up in the same amount of traffic another city block over.
Today its fairly warm, about 25c and Im sitting in traffic that isn't moving and the bike fan is going on and blowing incredibally hot air at me.... After a while traffic finally started moving and I put my bike from N into 1st and as I am releasing my clutch to start rolling the bike dies. I checked the kill switch, its still on, but then I try to start the bike by pulling in the clutch and pressing the start button.. the motor didn't turn. I stopped for moment in a panic with traffic behind me, (Why dont these bikes have warning lights or hazard lights?) I kicked the bike into Neutral and hit the starter button and it started right up and I was off... it didn't die again on the way home.
Im a little concerned but probably shouldnt be... I dont think i've stalled the bike, I never have... but it died the moment it started rolling.
Can anyone provide some insight as to what happened or how to prevent this from happening again? As far as I know the battery is fully 100% charged and its given me no other problems as of yet. Can something like thinks happen when it overheats? I was sitting in tons of traffic on a hot day not moving for a long time between lights.
1) It's still tight at 2200kms. Mine didn't really loosen up until it had a good 10,000kms on - nearer to 13k if I'm honest.
2) When hot and new mine did the same. It's important to remember that the algorithms used in N and <gears> differ. The fuel/ignition tables are different.
3) I loaded a new set of AFR tables into the R3 (gears 1 to 4) at the weekend and mine did the same yesterday in heavy traffic - 30ºC or more.
As I'm bedding in a new AFR map - I sort of expected it. Prior to hitting the jam - I'd been at 3500 in top.
I believe the mix is too rich. When the bike gets VERY hot the ambient temperature sensor WILL increase fuel richness.
The problems SEEM to come as the throttle lifts off the stop. Do a 15 min tune.
