Left Cylinder Not Firing

[MIABanshee]

Hey guys, Just rebuilt the top end on my shee and now the left cylinder isn't firing. It idles OK but right when I try to put it in gear and ride it , It barely runs and the left cylinder isn't firing. I switched the plug wires, Compression is 145 PSI on both sides, cleaned out the carbs, the choke tube is on,the plugs are good, the reeds and boots seem fine, and the carbs are in synch. Any one have any other suggestions... I dont know what else to try...One thing i noticed is that gas is spitting out from the overflow tube on the right carb but the left is the carb thats not firining. And the fuel lines are flowing fine and the whole TORS is removed.

If all that is in synch, then u might have a problem in the ignition.

Any one else? Update: It seems to idle and rev up ok in nuetral but right when I put it in gear and let out the clutch it either dies or it will barely move and the left cylinder will fire only once in a while. I also switched the reed cages, i dont think theres an air leak any where. As for the fuel leak I checked the float height and cleaned everything and the right carb is still leaking. So the left cylinder isnt firing and the other side is leaking gas out the over flow tube. I cant think of any thing ielse and this is starting to get me mad. DOes any one have any other suggestions.

 

EDIT: Just saw a tiny drip of coolant coming from the head right side. Could this have anything to do with it?

try reversing your spark plug wires. you said the left side cyl has trouble firing. by reversing the wires, try running it again and side if the troubled cyl switches to the right side. if so than its probly a bad coil.

I tried that and the smae exact thing happened.

make sure you didn't put your pistons in backwards, i had a brain fart and did that, and it had the same problem

i don't know what mods if any u got to motor but try race fuel.if i run pump gas in my motor the right cylinder dies .i tried everything to get it to run on pump gas and nothing would help it .i really wanted to run the drags and told my son i was running it anyway .i put some of his turbo blue in it and it grabbed both cylinders and man did it run .don't know why it drops right cylinder on pump gas but it does and the only way it will run on both is on race fuel.try it ,it might work for you.

this happened to me also. check for an air leak on any of your seals. that is what my problem was. after i put a new o ring on my head the shee ran great.

How do you know the carbs are synched? Don't use the sight glass to synch them. Do it the old fashion way and check the slides visually all the way up.

I did do it by taking out the air filter and looking at the slides. They move evenly.

Make sure you are getting spark through the spark plug. If you don t know how to check then, take the spark plug out of the cylinder, plug it into the spark plug cap, then with RUBER handled pliers hold the spark plug cap with the spark plug in it and hold the fireing end against one of your head bolts, and kick your shee over a couple of times.You will be able to see a spark jumping across.That will cancel out the whole spark thing because that will tell you that everything starting at the stator all the way to the cap is good. Let us know how it works out. You might experience a slight shock but nothing that will kill you.

this thing idles perfect and revs up awesome in nuetral and starts on first or second kick but right when I put a load on it just wants to die , both cylinders run crappy but the left cylinder barely even runs.

Yeah it will rev good and idle if your firing on one but will not move because of it. This might not even be your problem but it only takes a few minutes to check. Its happened to me before thats why I said it.
