have you ruled out electric problems? last summer my sj would lose a cylinder and sound like a person with a flemmy throat. It would wash a plug clean too. Ended up being my coil. Ya never know.
Weird plug readings**Updated W/ pics**

I thought about that but this thing is only a year old. I guess any electrical component can go bad anytime though. I need to do some research on how to check the coil. LOL I bought a brand new Fluke multimeter a while back but I don't really know how to use it.

I just checked and it has spark. This is just pissing me off now....

Good luck man. Things like this drive me CRAZY! If it was me I'd go ahead and replace the gasket between the cylinder and the case, just to be sure. Did you check your reeds? It sucks to have such a frustrating problem.

change your base gasket then check your plug readings. you couldve tore the gasket when you rocked the cylinder, how did you put on the girdle kit without taking off the cylinder? use a stud tool?

mine had spark fine but the longer i ran it the worse it would get. The longer i would ride the longer it would take to clear out the 'flem'.

Electrical gremlins are the worst. I might as well replace the base gasket while I have it tore down again. It looks like it will be down a little while anyway. I had my intake off not too long ago and the reeds looked perfect.
With the cylinder still on I used a 6 inch long 1/4" socket extention for the tap to chase the threads. That way the studs go in easilly with a little antiseize.
I think were onto something here. Mine will start out running OK then start to go down hill. The longer I ride the worst it gets. I'm just going to rip the coil out tomorrow and get a new one.

I think you are right. I'm going to take it out tomorrow and check it.

If the wires are long enough, try switching the wires and see if it moves to the front cyl.
Put your meter on the 20k ohms scale if it has one. If not pick the setting that is at least 15k or so. If you have MSD or stock plug caps you should read between 3.5k to 4.7k ohms. If you have NGK caps you will read around 14k or 15k ohms as these are resistor caps. If you do not get a reading, wiggle the wire around near the plug cap and see if it will read. This will indicate a broken spark plug wire. Stock wires are only 8 or 10 strand and fail due to vibration. If they are broken too far back to just cut back or are broken near the coil then they should be replaced with a good 20 strand wire like RD or JSS uses.
A very black carbon deposited piston usually means a lean condtion, a clean piston usually indicates rich. Sounds opposite but the rich cyl with extra fuel actually washes the piston and keeps carbon from building up. Do a search for " piston wash " and how to read it.

ok what im getting at is you didnt use the nuts on the head to tighten in the studs did you? like when you were tightening the nuts for the cylinder on the head the studs werent spinning too in other words using the nuts to tighten the studs? if that happened your torque settings will be way off. install the studs with a stud tool if you didnt.
you shouldnt have that leaking from the bottom of your cylinder, whether its the problem or not i would def replace that base gasket.

I'm going to try that today. They are long enough.
Thanks for the "how to" Keith. I'll give it a shot this morning.
I did accually. All i did was snug them down like the instructions said. The studs didn't turn while I torqued the girdle bolts.

have you tested the compression???
what does feel like where the dome mates w/ the top of the cylinder??? Is the top have a lip to it??? run your fingernail accross it and feel for a drop in the sleeve.

Compression is good. I checked that yesturday. 175psi in both with my cheap gauge. The top of the cylinder is smooth as well. Sleeve has not dropped.

did you try cutting the plug wires back? the the first and easiest thing to do if dropping to one cyl while riding....

That was the first thing I did after it dropped a cylinder the first day out while tuning. It got better but still ran like ass. After a long talk with John @ JSS this morning, the wires are more than likelly the culpret. I should have it back in a week or so.
