im really sorry if this has been covered already,
heres the full story,
Decided to build a new engine for my track bike ( 05 zx10r )
stm slipper clutch
balanced and polished crank ( standard rod and pistons )
block jetted to keep more oil on the crank,
head built to kawasaki race manual spec, ( ported 1mm larger inlet and polished )
kent cams ( kaw 25's ) degree 105, 105 as they request.
uprated inlet valve springs and shimmed exhausts,
2 degree ignition advance
ngk race plugs ( yes the £200 ones )
micron full system
.40 kit head gasket,
Heres the problem:
put the engine through 200 miles soft running and 10/12 heat cycles
tunning on the dyno started well, hp was looking good but then right at the end on the last couple of full throttle top end fueling adjustments .....it let go!
11500 rpms the bucket on cylinder 3 inlet smashed and dropped the valve...as you can imagine i was over the moon :-)
anyway i wanted to ask two things:
1, could i fit the 2006/2007 head to the 05 block as im struggling to find a head? ( i know the inlets are 1mm smaller )
2 is there any other mods or head work that ive missed that work well?
thanks in advance for your help guys
