OK so I know this isn't related to the original post but I didn't want to start a new thread. Had a little issue tonight while changing my front rocker box gaskets (the front has a leak in the area of the front dogbone mount) and had the entire thing back together minus the top and was torquing the last of the hex bolts (the 7/16" bolts (3)) and the last one didn't feel right and i was no where near the torque spec. Needless to say it snapped. Luckily me neighbor was pitching in and after removing the rocker box and new gasket it was evident it wasn't coming out without a fight.

So my neighbor is taking the head to his shop as he has the proper tools and is going to remove it tomorrow. Now to the info I wanted to share and ask opinions on; the front piston was caked with a pretty thick layer of really hard carbon and there was a carbon ring on the cylinder had a carbon ring in the area above the area of the top ring. I looked at the back, albeit through the spark plug hole with a focused light, and could get a decent look at the top of the majority of the piston an dirt was actually shiny with very little carbon at least what we could see. The rear piston was noticeably cleaner than the front.

Is this a normal condition? Does the front really use that much more fuel, or is the rear cylinder running more lean than the front causing less carbon build up in back? I mean the from piston was caked (top). Since the head was removed we decide it would be best to change all the involved gaskets on that cylinder and removed he cylinder which allowed me to really clean the front piston. Has anyone seen this condition and what contributes to this? Thanks for allowing me to drag my troubles out for all to see....
It could be a bad breather. They are about 12 bucks each so you might as well replace them while you have it apart. When I replaced a bad rocker gasket in mine, I found the gasket for the breather pinched allowing oil to pass by into the intake. It came from the factory like that.

Smoove, thanks for the help and your replies! I'll check this morning, we were up pretty late screwing with that and I plan to do as much cleaning as I can today til I get the head back. My wife was hanging around garage with us and my neighbor said we should just to a 1200 conversion since we had it this far, you shoulda seen my wife's face! Anyway, I'm crushed while I wait on this but better to do this right...

Got the head back tonight, haven't done anything with it though but start to clean it up from all the carbon. After reading and looking at pics I have to agree that it definitely is the result of the oil blow by from the breathers. I got the piston cleaned off really good and need to tackle the head while I wait for the gaskets and cylinder. The carbon is really cooked on the combustion chamber. What are some good ways to clean this off?

I can't wait to lose the stock A/C but want to get rid of those breathers into the stock air cleaner, can I eliminate the breathers before I get a new AC?

I'm sure others will chime in but soak the cargo parts in Pine Sol. May take a couple of days but no scrubbing.

So got my parts back from the shop on Saturday night and put the motor back together today... Even with good ole Murphy it all worked out. I put the cylinder and head on torqued it to the specs and then reassembled all the bits and pieces, cleaned up the garage then put the key in, held my breath and it fired right up and sounded great. I let it idle some, varying the throttle then shut it down to check for any leaks. Everything looked OK so fired it back up and took her on a cruise.

While it was apart for a week I cleaned everything i could, I had nothing but time. I put new seals in (intake, valve, etc.) along with new gaskets when I reassembled. Cleaned the valves, piston, etc. and I swear that the bike is running noticeably different in a good way. The idle seems smoother, still Harley but smoother, acceleration is smoother and it just runs better. Now I haven't taken it on the commute to work but I'm very interested to see how the "vibration" settles out.

To more accurately explain the vibration that started this thread this is what I was experiencing; Sportsters vibrate and I know that, mine always did an dhas spots that vibrate more than others. The Vibration I wrote this about was when a normal vibration in the RPM scale seemed to amplify after I was riding the bike for more than a half hour or so. If I was just cruising to the store or a shorter run that same spot in the RPM there would be a mild vibration that I could ride through as normal vibration. I just noticed it got really bad all of a sudden. Enough of boring everyone, I'll update after I get some cruising in (supposed to rain here tomorrow so we'll see).
