received zx14 head & placed it on the block looks impressive with big weight & space savings over ca18 de/e heads. weighed heads below including rocker cover
zx14 ninja 12.5kg / A15 H89 & cam is 11.5kg / CA18DE 24kg

ca16de block 78mm bore beefier walls w/ mains 36kg,
ca18de crank 13.5kg, rods 2kg, zx pistons 1.5kg, front timing gear and bits 5 kg, sump 3.5kg.
short ca18de block as above with zx14 head = 68kg

Plus Alt 3kg, inlet manifold 41mm quad carbs 5kg, 4 kg flywheel and 5kg clutch = 85kg

lighter worked crankshaft -1kg, light crank pulley 2kg,
and stainless headers 8kg total weight +/- 92kg

Thats 1853cc (xx14 is 1352cc) with 500cc more and maybe
over 200hp at much lower than 9000rpm stock zx14.

zx14 slugs 25mm comp height 136.65 c-c e15et prepped rod
on modded crankshaft will raise RSR from 1.591 to 1.635
good for 8000rpm redline and 20cm long inlet manifold.
(zx14 RSR 1.844 redlines at 12k rpm max power 9200rpm)
If I keep to 7700rpm redline engine should be very strong
and cutout ignition at 8250rpm for extra safety.
Not sure about camshaft being ideal for that rpm but will
open up the bike ports a tad for the bigger capacity.
