I noticed the rear cylinder on my 06 RG started leaking at about 30K after Patriot Harley of Fairfax, VA built my 103. Shortly after that I started hearing what I thought was piston slap. Turned out to be a blown head gasket. During the repair process, indy found that the crank that was installed had a runout of .019" which caused a lot of damage to the cams, cylinders, piston skirts and everywhere else that the super fine glass like metal circulated. Patriot Service manager told me that happened, blown head gasket and excess runout because I didn't do the proper maintenance on the bike.
The only other thing I did was replace the cylinder studs. One stud turned out when I was removing the headbolt so I just replaced them all. $16 and 10 minutes of work.

I know its an old thread but did you replace the oring on the bottom of the cylinder also or just the oil return oring? Mine is seeping on my engine and its leaked since the 106 kit was put on. Going to have the heads off in a few weeks anyways so I figured it would be a good time to take care of this also.

I put a big bore kit in my 05 flht. ended up with the smallest amount of oil weeping from the bottom of rear cylinder. tore it all out and put a straight edge on the base of the cylinder and I had put the smallest nick in it. A machinst recommended that I put a set of cometic gaskets in and problem solved.
