ok, now I am having a hard time believing that I have managed to fuck my nc30 engine (the story is below if your interested)
so the whole point of this is now I may possibly need a new engine and does any kind kb'rs have a spare one lying around that they would be willing to sell to mwah? or do they know of any available
and more importantly do any of you fullas have any advice one what I should do and what I shoud look for
cheers

now the story goes something like this
last weekend I was out riding with my step-brother and step-father and My bike drops a cylinder and refuses to start (now when I say dropped cylinder I dont mean running on 3 with the 4th firing every now and again I mean only 3 cylinders firing but it wouldnt run for any set amount of time) and so I pull the and tank off to have a looksie because I was thinking fuel blockage but there is only so much you can do with a roadside toolkit so I put it back together and try to bypass the fuel pump (blocking off the little pipe that sucks and then manually sucking on the place where that pipe goes and hey presto she fires and runs sweet, lets reattach the pipe and hope she stays running so I take off down the road ahead of the others and I get a grand total of 3.8 km down the road before the same happens again and this time she is truely dead and no amount of coxing with get her to fire (now its trailer time)[insert roughly an hour of laying down in the sun while the others return with the car and trailer]
later that night I have the bike in my mums garage and can look at it a little more comprehensively first thing I do is pull the fuel pump apart but no fault can be found, bugger I'll have to look elsewhere, so I did for until some horrible hour in the morning without any success. The next morning dawns brightly [I know cos I was awake] and after a couple of minutes of tinkering I suddenly remember how I had initally thought it was a fuel blockage and cursing my memory I blew really hard down the fuel line and it seemed to get a little easier after a bit (whether it was jsut cos i blew all the fuel into the carbs i dont know) so i now connect the fuel lines and start to turn her over and she almost immediately fire and purrs away quite happily and the throttle response is just like it used to be right then it be test ride time shoot off up the road to test it (yes very irresponsible I know) but she still isnt running properly and is still misfiring but all 4 cylinders are running. I am now thinking valve clearences and carb balancing will fix the problem so off to a bike shop it goes for a tune up
a couple of days pass and i recieve a call from the mechanic who is telling me that he pulled the airbox cover off and the airbox _full_ of oil (which it definately wasnt when I put it together) alerted to this he ran a compression test and all 4 cylinders where around 65 psi and they should be 165psi so they are _way_ down (i queryied this and he said it was with brand new guages and he also tested 2 other bikes cos he couldnt believe it) so he checked the valve clearences and the came up fine so he stopped at that point wanting to talk to me about what do to
