Sorry for all the questions. I have never heard of this before and am considering sending you a couple of my new engines for this.
Thanks!
I do just that....I lap the piston so it has a closer tolerance to where it needs to be in the sleeve.... on some engines it is not needed, but on others it can make a massive difference...
