Jardine cackle and pop

Thanks ,its heartening to know its not normal.
I was told by someone who used to work there that the dealer did have it and he could sometimes borrow it.
But he is a salesman at another dealer now,I dont really want to get involved with him after I didnt by the bike he was trying to sell .

Can't say about Oz, but in California the dealer is VERY limited what options they have. They cannot take a chance on loading anything but the factory tunes, which will include the TOR's (for "off road use only) but that is about it. Too much risk for them to get much outside the lines when you are dealing with the Air Quality Management District. If you want to run an aftermarket exhaust you will need a means to tune the bike, (Tune Boy or PC) and someone capable of tuning it.
