I have a 1995 zx7 and i keep fouling plugs... i have hindle pipe the carbs have been tuned to the pipe. i just dont get it.... HELP!

 

Need a better history than that!

 

Ok better story. My bike will start fine and ride fine for a while. Then it will start missing just out of the blue. Ive put new plugs in and wires but i still get a miss.can someone tell me how to lean the bike out a little

 

Don't always assume it's a mixture problem.Yes check the usual things like clean air filter and carb float levels etc but don't forget that bad ignition means unburnt fuel causing misfires. Do you have a healthy blue spark at the plugs? Is the battery good? Etc.

 

exactly. At what rpm's and engine loads does the "miss" occur?

 

i use to have this problem ALL THE TIME..
very annoying to keep replacing plugs. I went through a lot of steps til I found the cause of it all. Not to say you would have the same outcome, but I'll give you some ideas on where to look..

I would be sure my carb was clean, check the floats and clean or replace the air filter as ninjabarmy suggests. when i had this problem I changed my mixture too on first instinct, but it didn't help. It wasn't until I took my engine apart for the winter that I noticed my cylinder is completly infested with carbon! i mean nasty. (first time i took it apart)
I dont know what your matinence shedule is like, but dont forget all the places carbon can build.

so I suggest do what's simple first, look through your manual if you have one to troubleshoot, make sure all is clean, check your compression, and good luck.
