I assume you are using premium gas. If not you should. Check the plugs. If they are white the bike is running lean.. Make sure the gap is set correctley for your bikes spark plugs. Also check the jet sizes in the carbureator for your modifications and elevation. If the bike was fine and just needed a tune up i would pull the map off and reinstall the stock one.

Hi, Jonathan if you have changed your engine size, fuel delivery system, air filter size or flow rate, mufflers or exhaust system or a significant change in altitude your carburetors need re-tuning and if your fuel system (gas tank, filters, fuel valve and carburetor) is contaminated with ethanol sludge, varnish, rust, dirt, water etc. or your bike has been sitting for months or years without running these components must be "PROPERLY" cleaned and reassembled "CORRECTLY" before any adjustments can be made. Tuning your carburetor is fairly simple once you understand the basic principals. You engine is a simple airbox sucking air in and blowing it out, it is finely tuned at the factory for maximum performance once you upset that delicate balance by changing air filters, camshafts or exhaust systems your performance may go down the and the engine may run poorly, you need to compensate the air-fuel mixture in the carburetor in order for the engine to run smoothly and at peak performance. If you are running multi carburetors you need to sync them first and make sure your air cleaner element is clean and dry for paper elements or lightly oiled for foam and meshed elements and properly installed. Here is how and where you compensate trouble: "TIP" if your engine "BOGS" you're not getting enough fuel.
1. Close to 1/8 throttle is managed by the air screw and pilot/slow jet.
2. 1/8 to 1/4 throttle is managed by the air-screw, pilot/slow jet, and throttle slide.
3. 1/4 to 1/2 throttle is managed by the throttle slide and jet needle.
4. 1/2 to 3/4 throttle is managed by the jet needle, needle jet, main jet, and air jet.
5. 3/4 to wide open throttle is managed by the main jet and air jet.
6. A wide open throttle is managed by the main jet.
If you are running lean, spark plug electrode color is white, engine runs hot and feels like it is starving for fuel you need to go up on the jet size or move the c-clip down one notch. If you are running rich, spark plug color is black or dark gray, the engine runs cool, and bogs down when accelerating you need to go down on jet size or move the c-clip up one notch. When your carburetor is properly tuned for maximum performance your spark plug electrode will be a light tan color like coffee with cream. If you prefer fuel economy over performance you can go down on main jet sizes until a satisfactory level of lower performance is acceptable versus MPH, your spark plug color will be whiter and your engine will run warmer. These tuning adjustments will only make improvements if your intake and exhaust system have no air leaks or sealing issues and the entire electrical system is in proper working order and you have no mechanical issues.

I took the stock air filter off my 2000 Suzuki Katana 600 and put a K&N air filter in it, when i accelerate it stalls out a bit before kicking up to speed. a slight lag then go.


Changing to a K&N air filter changes the air/fuel mixture for your bike, and you're probably hitting an overly lean spot before things start to even out. For bikes still running carburetors, which I think you have, you can compensate for this by changing to a slightly larger idle jet. Your main jet is probably fine (it's kicking in after the lag); it's the crossover from idle to main jet that's causing the flat spot.
Talk to your dealership parts counter to get recommendations about jet settings. They may suggest, for example, to keep your existing idle jet and go with a different main jet. Expect to try a couple different setups to find one that works best for your bike and your riding style. I would highly recommend keeping your original jets, though, in case you ever go back to the stock air box.

new exhaust is to much for computer to figure out, since its flowing a lot more air , engine management cannot figure out fuel ratio hence the o2 sensor and knock sensor. u will have to install a performance chip or have computer re figured for new settings.

I expect the lack of back pressure from the new exhaust pipe will have a lot to do with it. If there is not enough back pressure, the reed valves won't work properly and no fuel will enter the engine.
Try the old exhaust system to find out.

Cutting out at idle


the batery is ok if the engine start avery time. Also the volts are ok.
Have you made any modifications on it? Sport exhaust, sport air filter?
Check also the air filter. Make sure is clean...
Idle speed should be around 1000-1200 rpm. You should have a screw to fix the idle speed. Check it on the carburetors area, or download the manual from internet.

Cheers.

Black exhaust smoke comes out of tail pipe, now it wont run how do I fix this and where do i start


Black smoke is a sign of too much fuel. First make sure the air filter is clean. Now note if the check engine light works, and if it stays on, get the codes read to get an idea of what error the computer has found. (A bad coolant sensor for the computer can make the computer think that it's well below freezing and increase fuel) Try these as a start.

Exhaust


Yes , You can By-pass the afterburner , but! have the engine tuned following doing that as it will not be running the correct air/fuel ratio. I fitted a Power Commander PC111 USB with a zero map , and had the dudes at Dyno Jet run it up on the Dyno and create a bike specific fueling map for it. It is AWESOME !!! I run 98 octain fuel and the air fuel ratio is 13.2:1(K&N AIR FILTER ALSO)
