Default Front Cylinder misfires, Rough Idle, sputters and dies

Ok, so here goes, Last monday drove into work bike ran like a stripe assed ape, got off and started her up for the ride home, turned onto the road and gave it some throttle only to have the bike sputter and had ZERO power, I was running on 1 cylinder, the rear. I backed off the throttle and she perked up? ok, away I went, got to the light and the idle was odd sputtered and died. I restarted and gave it throttle to turn and **** near hit ground again NO power running on 1 cylinder, woohoo 1 cylinder MOPED...I nursed to Wylie Texas all the while dealing with 1 cylinder under throttle 2(sometimes) if I backed off the throttle. pulled the plugs with a buddy of mine and thought the front spark was weak? so I/we replaced them both. started her up and it seemed fixed????

2 days of crappy rain later, I road her into the office today, and altho it seemed ok, the minute the initial warm up idle wears down it's rough, sputtering and dies unless I keep revs up and if I really rev it I can drive but it back fires flames coming out my front cylinders pipe. I have checked the pair valve tubing, unplugged all the connectors I can find inspected them, resealed them with dielectric grease, including the plugs, I sprayed carb cleaner between cylinders(checking for the vacuum leaks) to see if the idle races, no difference.

I am at a loss, if I work upto speed she runs just fine, if rpms drop too low she starts surging sputters and dies. won't idle, goes into fuel saving mode under throttle and fires on 1 cylinder only and I can smell gas when this happens by the way. any Ideas will be entertained, photos of gals optional, I need something to smile about.. bike runs great for 37k miles and then 1 day all **** breaks lose, I would have expected this kinda thing to creep up on me not all at once.

Have You checked the fuel for water content, the air filter could be wet or plugged, spark plug wires could be leaking or carbon tracking?

Yeah, air filter is fine, on or off it does the same, replaced the plugs. my 1 thought on it was weak spark? but if so, why does it seem to run ok is a work slowly upto speed. the fuel is fresh with seafoam added. I thought fuel first.

Check the resistance on the plug wires....if they both read the same, then they're prolly OK.
Though, they could be leaking due to carbon tracking......try rubbing some WD40 or similar into the wires using a rag.

Also, You may have a sensor problem deeper into the ignition system. This is where a factory manual may help.

Another test I would perform, is a compression test on both cylinders.

Just a thought.....has the pair valve been disconnected yet?

I could ALWAYS use a hand from someone experienced Dog, I read several post here with Similar symptoms but in different situations. I checked as best I could those fixes/causes. NO the pair valve is still there, I did however disconnect the hose and use new clamps to reconnect when that had zero effect.

I am gonna have to buy a manual, as I cannot locate any info or diagrams on possible vacuum hoses other than the pair valve.

WesH, I don't normally comment about these things as I don't profess to be a Bike mechanic, but most of the others are missing the obvious here (the common denominator) IT IS ONLY HAPPENING TO 1 CYLINDER.

So, what is unique to that cylinder - Not bad gas in your tank. Not the pair valve....but Plug, Plug Lead, Coil...

My bet is a short in or around your coil, giving weak spark and the bike will run fine when you match your fuel demand with the weak spark (giving a good - be it Small, burn). Look for bad connections in the first instance (this is easier said than done, most times. But, the fact it isn't intermitent will make it easier to find - If this is actually the problem), check for tracking on your plug lead/cap (as mentioned earlier), check lead resistances (both of them should be roughly the same). If everything checks out OK, then I would check your coil itself. They can actually go bad (just like that)

As you said, the bike ran fine for 37k miles, so it will be something that YOU CAN find... (And when you do, you will NEVER forget it).

Just my 2 cents work WesH.... But my bet is definitely Electrical - Not Fuel.

Hang in there, you will find it.

I thought maybe the front coil has gone bad, it would explain everything. I am leary tho as in all other cases it was fine and was something else..

How hard would it be to swap the coils and see?

from previous postings, they are different, therefore, it's a no go? on a coil swap
