Oh, and where in the world are you?

Thanks you Dave for your response,

ahhh I should have mentioned that the bike was capable of reaching just under 200kmph but this weekend did not pass 140!, if it was jetting, wouldn’t I also have problems with 1st and 2nd gear? Aftermarket bits air filter, expansion chambers and exhausts but nothing has been changed on the bike since the above speed was reached.


I am in Sydney Australia.


Thanks for your help in this matter.
