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.
-Pulled carb, completely dismantled, and cleaned every jet, orifice, carb body
-New air filter
-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,
