Anyways, some of you know the story that I bought my bandit and it ran a little rough, and I found out it had a super dirty airfilter. As it turned out, it starting running worse and worse then wouldn't run, and now even with a new air filter it will not start at all. I pull out the spark plugs and they are just soaked with gas. I pulled the carbs all apart, and they looked perfectly clean, like they had recently been rebuilt (which they had). I put everything back together, cleaned the sparkplugs, and it still doesn't want to go at all. I ended up taking it to a mechanic who again took the carbs apart. He said everything looked perfectly fine, 2 floats were a little out o adjustment, so he bent them up and it didn't really make a difference. He put new spark plugs in, and checked for spark, and it was good. Still didn't run. He gave up on it because it'd take too much time for him to diagnose the problem. Any ideas would be appreciated. Thanks.

Oh, incase you need any info, the Bike is a 96 B600 w/ an aftermarket exhaust can, k&n air filter, and a stage 2? jet kit. It has previously ran well with the jet kit, so I do not believe that to be the culprit. I'm just curious why it started running worse and worse while I was riding it. It got to the point where it would bog down going downhill while I was riding it no matter where the choke was or how much gas I gave it. It eventualy stalled out and never ran again. If I try to start it without giving it any gas, it doesn't even remotely sound like it wants to start. It must be something big I'm missing.

try replacing your choke line....not really sure if it will help but it sounds good

I could try that. I can clearly see that the choke cable is moving though. Do you think the cable is snapped?

Is the new filter a K&N replacement style?
How much oil is on the filter?
Have you tried starting it with no filter installed?
(for troubleshooting purposes)
I assume with the new plugs, they were checked to be sure they're sparking nicely, so as to rule out ignition issues, right?
How about a compression check?

My '99 B6 started running like crap with a K&N, and when I went back to paper it started running great again. I don't know if it makes enough of a difference that the bike won't start at all, but it's worth taking a look at.

I'll give it a try when I get home. I figured the k&n would flow more air than the paper, so I figured a flooding issue would be worse with a paper airfilter. I'll give it a try when I get home.

Yeah, I checked for spark, spark is good, plugs are new. I have not done a compression test, I'm not quite sure how I could get my compression tester down into the spark plug socket. I'll look into it.

Your fuel petcock could be bad? Try running the bike in reserve mode to see what happens. Have you checked the diaphragm? Many times with carbs being taken apart over and over it can get damaged.

silverbandit96 · « **Reply #9 on:** November 17, 2005, 01:52:33 PM »

Well, I don't know what happens when a petcock is damaaged. I mean, it flows gas fine, thats why the thing is flooding, are you saying it might flow too much gas?

Red01 · « **Reply #10 on:** November 17, 2005, 10:11:41 PM »

Actually, even if it flowed too much, the float needle & seat should take care of things. Now, if the needle/seat is screwed up AND the petcock is on PRI (or flows gas thru because of some other defect), that will cause a bad case of flooding.

Paul's trouble-shooting procedure is valid. Did you remove the newly oiled (possibly over-oiled) K&N filter to see if the bike would start (clean the plugs again before attempting to start)?

An earlier post of yours referred to oil being "thrown" to the rear swing and tire...better follow Paul's suggestion and performorm a compression check!
