Any power loss, or lack of power for that matter? start with the easy stuff. maybe unseated spark plug?

No lack of power that I can notice, but occasionally it will get hesitant with the throttle and flash an FI light. I really don't know. I pulled off the air box today and noticed the #1 spark plug was loose. I tightened it and put it all back together but the tick continues. I'm pretty sure it's a valve because it smells like exhaust around the block where the camera is. Thanks for all the help and suggestions, I just need to get some time to check the valves.

doesn't sound like CCT, more like valves. does it go away or get louder under load?

It gets faster with the rpms but not louder. The sound of the motor while riding overtakes the tick.

Definitely sounds like bad valve tap or rod knock. Hopefully not rod knock. How many miles are on the bike? Did the seller disclose any info on the tapping?

12,300 miles. The seller thought it was the sound of the injectors but I'm certain its not that. My buddy has the same bike and his does not make ticks like that.

All times are GMT -5. The time now is 06:39 AM.
