Hi folks..
My '99 Suzuki Katana recently got a problem with the carbs due to some dust under the float needle, due to which the fuel overflowed and filled up the air filter, and even got into the engine apparently..
But anyways, now, I got it all cleaned and put back together, and the bike seems to be running smooth in the low rpm range..
However, there's 2-3 problems that now I'm resolve.
1. It still takes quite a while in the morning to startup (with couple of long self-starts)
2. It gives a whole lot more of smoke through the exhaust than it was earlier.
3. The acceleration and running is absolutely flawless in the initial range, but right at 6k rpm, the bike apparently seems to choke and doesn't push beyond that point... This is what I'm majorly concerned about..!

So help folks!! HELP!!!

Regards,
J.
 
I'm not fmailiar with the specifics of a Suzuki Katana, but you should look at the following items when you are troubleshooting.

1. proper float level, choke sealing properly, gas-air mixture, choke linkage, compression, ignition timing, spark plugs

2. blue smoke? Cylinder, rings, or valves could have been damaged when dirt got in the cylinders. Black smoke? Not enough air- check choke, air filter, gas-air mixture.

3. dirty air filter, bad plugs, incorrect timing, choke not releasing, spark advance mechanism, valve lash, valve springs
