half the gas mileage and black smoke
Basic setup information
1270 kit
Full yoshimura system
Power commander
K&N filters.
92-octane gas
Over the last week, I have noticed that my bike is burning a lot more gas. So much that I get half of the gas mileage that I used to get. No settings have been changed on the bike. I burn so much gas that I have to idle at 1500 rpm just to stay running. Anything less and the bike dies. The power commander has the base setting of everything being set at 0. The bike sputters and bucks when driving less that 3000 rpm. When driving above 3000 rpm all seems normal except for a delay in the throttle response when I get back on the gas. It takes about 2 seconds for the engine to spin up to the throttle position. I have never seen anything like this. When parked and revving the engine, there is a cloud of thin black smoke coming from the exhaust. Then it dies again. The tip of the exhaust looks like black charcoal dust. Any ideas from anyone?

There is a 99.9% chance that your Power Commander has gone "South" for the winter. Immediately do 2 things!
#1 Bypass the Power Commander and hook it back up as stock!
#2 and even more important immediately change your Oil because it is now fuel poluted and is destroying your engine. I would change once with regular Oil and not change the filter and then change the second time with a new filter back to what ever you were using.
The Second Change is provided the bike is now running correctly with the PC Bypassed!
Last, Stop riding your bike until you do these things because all you are doing is Killing your engine (Provided you have not already done so!)
To anyone reading this, These bikes are not Cars that you are out on the "Open Road" with your family and late at night and no other choices than to drive it back home or to the dealer. When you bike starts to run like Crap, stop riding it until it is fixed because unlike the car, you do not have steel cylinders, on 2 to 3 K rpm rev limits for your driving.

If Powercommander doesn't fix it go for the tps.... Mine went bad and did this..... Less than 70 miles a tank and black sooty smoke..
For reference the 2000 zx6 tps should be the same... The zx12 tps they want to sell throttle bodies and all...

I agree with Vince, check the PC and change the oil.

PC is known to do this sort of thing...and its the easiest to check, simply unplug it and plug the stock ECU back up like normal and see if that fixes it...do what Vinnie said, change the oil, and invest in a new PC....

ya.. richard.. I agree.. but you have to remember that 95% of PC failure on 12R's are cable routing related...
first thing to do is disconnect PC... next thing to do would be to dump error codes (if any) logged in the ECU.
