Is it possible to flash the computer on an FI bird? An '00 if it makes a difference. I'm trying to chase down a rich mixture problem which has the bike belching black smoke when I get on it, and smelling bad (too rich) when at idle. My muffler tips are getting that black soot also, I haven't checked the plugs which have 5000km on them. The old ones were a nice tan colour.
The bike has been running rich since I bought it.
It was purchased with a 4-2-1 exhaust on it which has since been replaced with an OEM.
I've already replaced the FPR and run two cans of seafoam (not all at once) through the tank, I'm sure by now it's all worked through.
I've checked the PAIR it isn't blocked off.
A new k&n was installed 5000km ago to replace the blocked up (pleats were completely covered) OEM filter, didn't change the smell or smoke.
The bike still runs great, I just don't want to start fouling plugs. I also get about 250km/tank.
I'm asking about the flash, because when I purchased the bike it was running rich with a 4-2-1 exhaust on it but the seller didn't know what was done when the exhaust as installed. I know you can teka and/or yosh box suzukis but I don't know about the bird.
Am I missing anything in my trouble shooting?
