Just tryin to sort it out.

You have a z1b, and built the engine with a z2 crank rods and block, and put bigger pistons in it. Or am I missing something? Cases trans and head are from a 900 then?
If I knew what I was doing all the time life wouldn't be any fun.

I'll take some pics in the morning of the blocks. The sleeves came out of a 750 and put in a 903 block then bored to 1015. I ruined the bores, then bought a 1015 block. I'll post them then.
