R.I.P 05ZX12R
managed to blow a hole about 3cm by 5cm out the front of my motor on saturday, she went off with a bang and a cloud of smoke.
on the up side it still ran, how i dont know, but i managed to get it home looking like a steam train as it smoked the whole way there. luckily it happened about 4km from home at the end of a poker run.

a hole...??
as in the radiator, as in the engine block? head? crankcase?? busted hose??? oil cooler?

most peculiar
more info please

Given the floggings that old mate has mentioned in the past, my guess would be that he has lunched a crank, and spat a hole in the front of the block through the radiator......just a wild guess though....

and he rode it home...........???

yeh, seen it done before......a mate of mine lunched a CB750/4 crank once, blew a hole out the front of the motor ( and half a piston and rod) - it actually caught fire as he continued to ride along but after a couple of k's, the fire blew out - he made it home ( another k or 2 ) as the engine was finally seizing up from loss of oil. Probably less than 4 k's from where he lunched to home ??

The crank still spun freely, because it only had <1/2 a rod hanging off the buggered big-end, so it wasn't actually 'hanging-up' on anything as it spun around ......the other 3 cylinders kept firing.......bloody funny to watch !!

thats pretty close to the mark only didnt damage the radiator, the chunk out of the block must of hit the exhaust. No. 3 cylinder obviously didnt like what was going on.
will put some photos up once i pull it down
