trying to fix base gaskets for good

FYI - found out about it from a top fuel bike engine builder - Three Bond. Also makes
it for some bike manufactures under their name like Kawasaki. Only stuff that I
like better than Permatex Aviation when its gotta seal and goes through expansion
and contraction over and over. IMHO.

wondering if ogre25 ever got his cylinder base leak fixed? did you lap your cylinders? if so, what did it cost you? do you know how much material you removed? did you have to compensate by using thicker base gaskets?
i have the same problem. replaced base gaskets twice (harley first, cometics second). neither fixed my leak. it never leaked before the rebuild.
i'm considering lapping cylinders and installing hayden oil fix along with a third set of gaskets. possibly using coppercoat or similar gasket sealer despite my local indy advising against it. not sure who's gaskets i'll pick this time. probably use the base gaskets that come with oil fix and get top and rocker gaskets.
any info you've learned that you'll share is appreciated.

I was going to update this thread in a couple days but this seems like a good time. Yes I did buy the lapping ring(about a $100) and lapped my cylinders, my guess is that I removed less then .005 of material as that is what the gap I had when using a straight edge on the base of the cylinder.
I used the Hayden oil fix as I already had it on there and a James metal base gasket top end kit. I also applied a very thin layer of gasket sealer on the base gasket(probably not needed but I wanted to make sure it wasn't going to leak). I torqued every thing back to factory specs.
I have put almost 500 miles on it this week after the gasket replacement, following my warm up practice to wait until I feel warmth from the rocker boxes before taking off, and then easy on it for 3 to 4 miles. I am VERY happy to report no oil leaks at all!!! I would like to thank all the people that responded to this thread and pm'ed me.
If you need any more details feel free to pm me.
