Coating stock block aluminum bores without sleeves

[Roger P.]

After heating up an 1127 block and dropping the sleeves out, I couldn't help but wonder if anyone had ever used a bare block and attached aluminum sleeves to the bottom, then had the whole thing nikasil coated for a 1400cc+, stock block sleeper. Lots of work and fiddly machining, but the riding season's over in Canada, so it's time to waste time on dreaming up impractical projects.

Are you on crack?

The block simply wouldn't be stiff enough to keep the bored in shape.

I've looked at the block  thinking about coated  aluminium liners,  better for heat loss and weight - not sure there's enough strength without liners - I haven't got past the thought process !  Would be very interested to hear from someone who's fitted Al liners......

gsx1400 does exactly that, nikasil bores. What other differences there are, I don't know, but no doubt someone will have access to a block to measure up
