I've had enough... blown engine
Posted: Thu Feb 26, 2009 10:12 am
Hi guys...
so... i've blown my engine up.
The bike dropped out of gear at speed and jumped up past 16000rpm before i had time to react.
cue horrible snap noise and then tapping coming from the engine.
no smoke from the exhaust so i dont think it is bottom end.
It's deffinitely on cyl 3 (when i cranked the engine over this cylinder remained cold, so the fuel isnt being burnt, or isnt being burnt properly.
So i need some advice.. i'll be taking the bike apart tonight - just wondering if there's anything i need to know about removing my engine, anything that i am likely to forget about and will have to do..
i'm hoping i've just killed or spat a spark plug, but i don't think that this is the case.
next i'm hoping its just a snapped valve that hasnt been mashed into the piston too much..
but worst case scenario.... i need to buy:
piston
valves
valve springs
etc.
now, my question is, where will i buy these from if i do need them ?
and how much should i expect to spend.
also.. does anyone have a head off a running bike for sale ?
Thanks.
Ben
