I finally got the bike back from the Dyno. What a saga that turned out to be...the first guy couldn't even start the thing after a month of having it so I picked it up. Turned out...as correctly suggested by people on here...that it was just the plugs.....I was spewing that it was something so simple and a "professional" didn't even think of doing the basics.
Next the bike went to Dynobike in Moorabbin.....I told him that he was arrogant smartass...

(that went down well...

)... he said the carbies had crap all thru them....I couldn't work that one out as it had brand new fuel lines, brand new tank (which was fully sealed when purchased), new fuel filter plus the carbies had been cleaned 3 times with carby cleaner, air, detergents etc etc..recleaned.
I went down there and turns out the brass jets in the carbies are...well...what I would call "stained". There was no dirt in any of it...the jets were just not shiny enough apparently...so I told him to get the bill...I put all the carby parts in a bag...put the bike on the trailer...he seemed to want to "front" me about the whole thing so I told him not to be a sook and to get the bill for what he had done so far...I paid it and left...

I don't reckon he will ever let me come back...

I think it was an affront to his ego or something.
Personally I reckon that the fuel "stained" the jets...that's about it...I think he wanted to charge me for a complete carby clean then go for what ever else on the bike he could "find" wrong...It concerned me that others would/might just believe whatever this guy says and pay the bill...What was worse was he would probably have used the fuel in the bike anyway and the jets would have turned out the same...so it was all stupid in my opinion...anyway..he doesn't like me...
So I put the carbies together, put them back on the bike and took it to Race Replica over in Brooklyn. They did have a few problems initially however they worked thru them and finally got HP at the back wheel. I know it's not a huge amount but from the info I have seen thats pretty good for this particular year and model as it is supposed to be the lowest horsepower 750 produced in that series (ZXR750 thru to ZX7R).
Anyway, I was real happy with the way that Race Replica tried real hard to get everything right even though they had problems. They did exactly what I asked, didn't ring up with stupid complaints about dirt in the carbies, which incidentally, had not been cleaned or anything when it came back from Dynobike just reassembled, and they got reasonable horsepower for this bike.
So now I'm looking forward to taking it out to a track and trying to crash

I live with fear everyday but on weekends she lets me ride.
