You want to Lilley-ize the engine but you do not want to by a new piston
cylinder set? Boring 1mm oversize will make some knocking noises without
a matched 1mm oversize piston. I've used the Brazilian sets, cost should
be around $300 for the 4 of them. German sets about $100-150 more. I
also like to use a "Total Seal" second ring. 2-piece gapless design
almost eliminates blow by.

Subject: Boring cylinder to oversize

Has anyone bored a WBX cylinder to oversize?

I have a basket case engine - (my first engine which  melted a hole in a
piston and scored the cylinder barrel) - and would like to begin a
rebuild.

I have three good cylinder barrels and would like to get a fourth --- IF
I cna find a good used one that is in tolerance. I would like to bore
them about 1mm oversize. Anyone have any ideas about what problems with
piston size and rings mating that might occur. Any recommendations? This
would be the beginning step for me to Lilley-ize an engine (where does
the royalty fee go?)  -[;<)>

Thanks for the input.
