The bike has been running GREAT !!
Last night went over a couple of towns, got only .658 gallons of gas as I don't want to be too low on gas, I like to be full when out of town just in case...
Rode around for maybe five minutes and left to head home. Cranked on it some as I left town, up to about 90+ - miles and hour, nothing over 8 grand. AND THEN.. the bike started cutting out, bucking, backfiring through the pipes, bogging on and off. Once in a while it felt like it shut off then came back on. I clutched it and it reved up fine MOST of the time, but under a load.. the same crap:( the next time under a load it ran fine W T F@$#%*?!!!?? I made it the twenty miles home, one mile no problems, the next mile the above mentioned problems.
I don't really feel it was the gas..seemed almost like an electrical problem.. but I'm no pro on this. If I was it would be fixed now.
I checked the plugs all looked good except # 1 that I have had a problem with running too rich.
I dumped a bottle of HEAT into it just as a "fingers crossed" fix. But I haven't rode it since. It starts fine. Just afraid to ride it and break down on me with nobody @ home to come get me.
So point a old man in the right direction if you would PLEASE.

If pro is opposite of con, then what is the opposite of progress?

The least likely is the no gas. Open the drain screw of the carbs that are not firing. IF you have dry bowls, then troubleshooting should be pointed at the fuel system. The problem COULD be no spark. Depending on WHICH plugs are not firing (spray test), you can swap wire from the same coil to narrow down the possible causes. Say #1 isn't firing. If you swap it with four and the problem moves, then the problem likely isn't the spark plug, ignition or coil but more likely connection of the wire to the coil or the wire or cap. If the problem doesn't move, it is either compression or the plug. Compression is generally a valve clearance issue on an engine that has not been recently repaired.

Also on one of my KZ1000s I had basically the same thing happen when for some odd reason one of the carbs decided to somehow turn to crap on a 5000 mile trip. That time I sprayed tons of gumout in the air intake while revving the engine and it cleared up.
321,000 miles on KZ's that I can remember. Not going to see any more.

Also make sure all wiring to your dyna setup is plugged together securely and the wiring to the coils is plugged in fully and not corroded. I had this on one of my KZ650s.

I am curious. It is my opinion that any cleaner sprayed into the intake will only enter the intake air. It would clean the intake and possibly the valves.
How would the cleaner enter the carburator fuel system?.

I sprayed water on the exhaust, all of it evaporated the second it hit the pipes. No run off .
I hope to pull the tank and petcock and filters this weekend if I can get an hour or so of that rare thing called free time:P But then again I have to replace the outbuild's well pump handle and hardware too :pinch: ( read dig a six foot hole three feet across )so the wife can water her garden And we all know what project comes first if I want to stay married:whistle:
Thanks for all the words of wisdom and ideas!!!
I'll let you know what if anything I find out.

So now I know for sure it's electical:pinch: . I had found that my #1 & 4 coil was NOT bolted down, it was just sitting in the holes. I'm real sure that was the coil my 12 year old was to bolt down last Winter.. I had hoped it was that.. NOPE. I checked all wires I could for loose or something / anything I could find. Nothing.
I didn't get a chance to change coils and see if it's the coils. Maybe later this week as the wife and kids are heading to Wisconsin early this week and I will be single for a couple of days;)
Thanks for ALL your help!
Pat
