I have a 2000 sxr 700, 49xx miles. Sled died 2 years ago. got to put a stator in last year and could never get it running right. the clutch side cylinder will not fire! Got back to it this year and its the same thing. Carbs have been pulled and cleaned several times by me and then by a shop. same thing cylinder will not fire. I have spark in all three plugs and even tried switching a coil. i thought that maybe under load/compressing it wasn't sparking. but its the same thing the cylinder just wont fire. every time i pull the plug out its soaking wet so i know it has gas. if you try driving the sled with two cylinders it wont stay running unless the choke is on. im pulling my hair out on what to do next. Reeds? bad compression? any ideas?
 

before the stator went bad it was running strong on all three cylinders the just died. i dont think it would have that low of compressin with just under 5k miles on it?
 
But u say u have spark in that cyl and a soaked plug. Spark and fuel is there so it should fire. 5000 is lower mileage but that doesnt mean you cant lose a cyl. I personally would try a compression test. To much fuel maybe?
 
Could be a dozen things but checking compression would next. When it died did you have any other performance issues (i.e. wouldn't idle, lack of power). Were the carbs cleaned prior the ride when it died?

If you don't have a compression gauge, use a bendy light and look through the plug hole for damage to the exhaust side of the piston... or,

While not very reliable especially if you're not "esperienced", placing a thumb over each plug hole while tugging can give a rough idea if one isn't like the others.
 
If the plug is soaking wet, that cylinder could be flooding - inlet valve leaking or enrichener plunger stuck open?
