Just bought my first bike and need some help.

1. At what engine temp is the fan supposed to start?
2. Key does not open rear seat latch. What to do?
3. o2 sensor on ca models. Where exactly is it located? I want to upgrade my exhaust with a slip on exhaust.

Thanks for the help.

 

What kind of bike and what year?

 

I'm not sure exactly where the O2 sensor is on the cbr, but on cars they usually try to place it as close to where the header meets the cylinder as possible. O2 sensors have to reach a certain temperature before they begin to work properly, so they like to put them in a spot where they can get hot fast.

 

2002 f4i.

 

Get a user manual.

 

The O2 sensor will be in your exhaust mid pipe. Look at the area near your rear break pedal.

I think the fan kicks on the F4's around 225ish

The key doesn't unlock the seat??? Was the ignition ever replaced? You might want to talk to a locksmith and see what he can do.
