2003 Kawasaki 250 Bayou Ignition Problem?

I am having some touble getting my wife's 2003 250 Bayou running correctly.

It first started with just random missing and crap when it was idling, then it would run good for about 5 minutes, and progressively miss worse until it wouldn't even move itself even WOT. Now, I can barely get it to run with the choke on.

In its current state it will only idle with the choke full on, and only for maybe 10-20 seconds. If I touch the throttle it dies instantly. That to me sure sounds like fuel, but I am fairly sure the fueling is as close to factory settings and should run at least somewhat.

The way this thing misses and randomly idles up and down, I thought for sure it is an ignition problem. But, I really need some more eyes on this. Possibly previous Bayou owners, because it has me stumped currently.

Attempted cures

Fuel

-Pulled carb, completely dismantled, and cleaned every jet, orifice, carb body

-New air filter

-New sparkplug

Ignition

-Stator resistance tested good hot and cold

-Coil resistance tested good hot and cold

-Unplugged voltage regulator, no change in condition

-Spark plug cap tested good

-Crank Sensor resistance tested good hot and cold

(with the specs from Kaw Manual)

-New CDI $$$$ ahhh

-Valve clearance also checked and it was spot on factory specs

-Valve timing checked

I think tomorrow I will check compression, and I guess for intake leaks.

P.S- Need to get this running, wife is starting to repeat the Honda, " I wanna ride commercials" LOL

Any ideas appreciated,

Jeff

Tried a few more things...

-sprayed carb cleaner around carb boot, lower end gasket, and near head gasket, No change

-fully charged battery, cleaned battery terminals, engine ground terminal, No change

Didn't get to check compression because I couldn't find the 12mm adapter for my compression tester.

-tested crank sensor with DVOM for voltage output, shows no voltage produced on 20V DC setting.

Do I need to test this with a analog volt meter?

Maybe this is the problem?

Factory manual says 3.6V or more

Getting tired of blowing money on unneeded electrical parts though

Well, I had it running today for a little while attempting tests and stuff on it.

I have to start it on full choke and then sometimes I can get it to rev and but I have to keep revving the hell out of it to keep it running. When doing this it will randomly cut out and sometimes flat out die. If I start it and leave it on full choke it will idle decent, but will also cutout and die at random. To me, It sounds like the timing is way off when it dies because you can hear it ping and almost sounds like the timing is way advanced. When it misses when I'm revving it, it sounds like an intake backfire.

Valve problem?

Hopefully compression test will tell me more tomorrow

I'll keep looking.

      98 arctic cat 300 2x4 hi rev choke when started
      By Its-always-something
      Have a 1998 AC 300 2x4, Just installed a new carburetor. Engine starts easy but the choke RPMs are very hi and take along time (5-10 mins when cold out). After engine has warmed up choke releases and it idles and runs fine., It does no have an electric choke. The choke lever is never used and it seems like an auto choke? Long story short, how can I lower the choke rpm levels?
       
      Also, carb came with a spare145 jet, not 100% sure what is installed. Could this impact choke RPMs?
       
       
      Any help and information greatly appreciated.

      2002 Quadrunner 250- Knackered cam and journal/"bearings", difference between 2001-2002 part and 2000 and earlier
      By kiriyaaoi
      Hello everyone, I just picked up an 02 LT-F250F the other day and have been in the process of tearing it down to fix some stuff- one of which was the cylinder base gasket leaking like a sieve. Well, I know why that is now, and I also discovered that someone had been in there before. I didn't take pictures, but it looks like it was probably run low on oil at some point, the cam journals and the "bearings" (for lack of a better term) in the head and the valve cover are totally wiped out, very deep grooves.  From what I know it's very difficult to repair aluminum in this way, so I'm trying to figure out where to go next.
       
      1. Have someone grind down the head and valve cover and fit actual bearings in since the aluminum is screwed, and have the cam ground down to match.  I have no idea what this would cost.
      2. Buy a replacement head+cam+valve cover.
       
      #1 I was hoping someone might have some advice on, but #2 seems like it'll (probably) be the more cost effective option.  However I'm running into some difficulty, it seems like the 2001 and 2002 models specifically use a different head part number,  11100-19B10, instead of  11100-19B01 like for all earlier models.  What exactly is the difference between them? There are obviously far more of the earlier heads because it ran for over 10 years.  Are they actually interchangeable? I've also noticed there are heads from the LT250EF that has 4 valve heads but also otherwise look identical.  Would those work as well possibly?  I'd like to not have to drop $500 on machine work or new heads on a $1300 quad that I'm already putting a bunch of new parts on.  Oh, and it has a new piston and the cylinder itself looks pretty good too, as I said someone was in here before me.
       
      Any help or advice would be greatly appreciated. I'll post pics of the carnage tomorrow.

      Good aftermarket carburetor
      By kawasig
      Hello there
      I'm having a problem finding a quality carburetor for a 1993 Suzuki Quad Runner lt-f 250 2x4. I find a lot that have 3-4 star ratings. And all so far don't have the right throttle Cable inlet at the top. The last one I got 4 star on Amazon has a threaded cable sheath rest that could be partially drilled to work. I would prefer to get one I don't have to modify. Any recommendations are greatly appreciated!
