2004 cbr1000rr
 

So I just purchased my new fireblade. I have one concern. When I but the bike in gear, with the clutch pulled in, the idle blubbers from 1100 to 11500 up and down. Is this normal? its got 6,000 miles and only after market part is two bros racing exhaust.

Hi, could be a myriad of reasons from the Fuel Pump, IAT and MAP sensors to Power Commander (if you have one) had the bike been Dyno ran when installing the exhaust ,and does it run like this when cold or after a run out:)

Professionals put on the exhaust. and no power commander on it. Does it when hot and cold. just blubbers after clutch is pulled in. bike has no hiccups while riding or any throttle response problems

Hi, if this only happens when clutch is pulled in then it has to be clutch related, try adjusting the clutch cable to eliminate any drag ,then use the idle adjustment knob to set the rpm
