I have this as a print out and its huge, I have it sitting with my bike for the time, so when it sells the new owner can have it or I will sell it on or get it binded and make it available for everyone so long as they pay for shipping to them and back to me

Ditto I also have the PDF so if someone wants to PM there email address I should be able to pass it on as an attachment.

Hey Newo you mind me asking what mechanic you use? seems reasonable for all that work, (not that I'v ever paid for anything done to my bike but could be about time it had a real good birthday)
I have also heard/read really good things about motorcycle doctors? who come to your house and do super work.

DrunkenMistake, Vacuum leaks aren't necessarily form a vacuum operated fuel stop valve, don't forget the carb diaphragms and intake rubbers.
It could be a fuel pump issue, MC19 are know for popping pumps.
When were the valve clearances last checked, carbs cleaned etc?

I actually have the service manual on my computer as well. If i were to ever perform the work myself I would probably print the pages required as I can't stand reading from a computer screen under working conditions like that.

The guys name is Toby, he works out of his home down the end of Forrest Hill Road, Henderson Heights? Can't remember the name of his company off the top of my head.

Valve clearances probably havn't been checked since the 24k service I'd imagine. She's done 47k now and well due for a check. Will be getting them done this weekend I think. I think I've just decided in this moment to send my girl to the professional because I lack the experience to do (in my eyes) a well enough job. In saying that though, I am definately going to start learning at the very least, simple motorcycle repairs and maintanence. I'd love to be able to strip my bike down completely and rebuild her myself but I'd say thats a long long way away.

Thankfully my flatmate is letting me ride his bike. Can't thank him enough.

Incase anybody has interest in the cause of this.

I pulled off all the fairings and had a long hard look at my bike tonight. Not going to do the work myself but I figured would be nice to inspect it for myself.

Among quite a number of concerns, I found that the coil pack leads all have cracks and in some parts you can see exposed wire, more so closer to the plugs where the wires shoot off in an almost 90 degree angle (which doesn't make much sense to me). Id say what I probably experienced on both this instance and back a few months was the bike trying to run on only 3 cylinders, or maybe even less as all the leads show very high wear. My understanding is basic but it would make alot of sense if the plugs were being neglected like that I suppose.

To what extent can an engine like whats in my bike run when one or more cylinders decides not to work for one reason or another?

It'll run on three and may possibly still run on two.
I'd get the leads replaced ASAP, I'd hope there isn't anywhere they are arcing out? Lead problems can (Worst case scenario) crack the coil housings.

I'll post the long dramatic story after I get my bike back.

Suffice to say that after all things said and done, It indeed was the coil pack leads (as I had thought). Water was getting in the cracks causing one cylinder to fail.

My experiences thus far with professional help has been both expensive (though I guess cheap compared to other shops) and quite unreliable. Will spill the entire story once I'm satisfied that I can close the book on this one.

mate dont stuff around with the crap mech, call george from motorcycle doctors. hes the boss when it comes to bikes. also dirt cheap too.

[Newo]

Get my bike back tomorrow (erm... today I guess)...

Will keep that in mind if I decide to go down that path again. My flatmate is heading that way so I'll make the suggestion. He was preparing to have work done with the same guy I just used and has changed his mind now after my experiences.
