HELP! need a little clarification

[Huff1371]

OK, so I have the high/hanging idle when the bike is warmed up. I've sprayed wd-40 everywhere to no avail. Thinking carbs need synced,  I pulled the right plug wire with engine running and nothing happens. Pulled left wire and bike shuts off, however if I pull left plug while reving it runs fine until I release the throttle.  So is the left pilot jet the culprit or am I reading this all wrong. I know spark is good because both sides shocked the bejesus out if me and it runs fine with throttle. Whoever is correct wins a beer or two if you come through the Shenandoah valley in VA.

If you pull the right wire and nothing changes and the left wire and the bike cuts off, only the left cylinder is making the bike run. If that is the case, your problem is in the right side of the engine. I would check the right pilot jet.

and/or the sync crew. mine did the same thing. adjusted sync screw and viola, runs on both

So tonight I'm gonna pull the Carb and check out the left pilot jet and gain acess to my sync screw as it still has a plug. Crossing my fingers.

dropit was talking about the screw in the middle of the carbs that adjusts the relative throttle position of each carb.  You were talking about the mixture screws on the bottom of each carb.  Both may need tweaking.

Didn't even think about that,  thanks

I still think you are looking at this wrong...

Right...um ...correct. my problem lies on the left side as that's the side that makes it shut off when I pull the plug. It idles on the right side but is just high. Unless I'm completely off in which case please let me know as I've spent all evening around Carb cleaner and it may be getting to me.

If I'm following you correctly, nothing changes when the right plug boot is removed and the motorcycle dies if the left plug boot is pulled, correct?  If so, that is demonstrating that the right cylinder is the problem.  Your bike is currently only running on one cylinder.  In a proper running bike you have 2 firing cylinders.  If one plug boot is removed the engine should run rough on the remaining cylinder but not stall.  Since nothing changes when you remove the right side plug boot, nothing was happening on the right side of the engine.  This is further demonstrated by the engine dieing when you remove the left plug boot.  If the right cylinder was working the bike would continue to run with out spark to the left hand side.  Since the bike dies when the left boot is removed, the left side of the engine is the only one that was working.  Hope that is clear enough

OK so I'm a dumbass. I really need to stay off the cleaning chemicals. If I pull the Right plug it shuts off. If I pull the left nothing happens. If I rev it up and pull the Right whilr keeping some revs it doesn't shut off(running on only the left at this time). But when I release the throttle it shuts off( with the right plug pulled). You are correct in what you said but I was backwards in my initial post. I'll banish myself to tard farm for one week.

[Huff1371]

So if I can try to explain it better, It will NOT idle on the left cylinder only. I really feel stupid because I was thinking "These people just don't get it"..

[dropitlow88]

Def sounds like a carb sync issue. Adjust the screw (the small one) in between the carbs near the throttle cable connection until it will idle with one side or the other pulled off (plug wire) you want the rpm drop to be the same whether you pull the left or right plug.

I had that problem with Trey. Was a flakey spark plug. Swapped plugs and it switched sides.

I posted once about the "Hillbilly Carb Sync" after I sucked the blue fluid out of my Motion Pro carb sync thing.
Do what is mentioned: pull a plug and see. Pull other plug and compare. Tweak the screw between the carbs. Repeat until both sides seem the same. Not scientific, but it does do a decent job. I did that on Phenix last night while I had the tank off.

So I adjusted the center screw and it helped a little, the I pulled the Carb and sprayed it out. I'm back in business.  Beers to all. Thanks
