I'm New to the riding scene but I did what everyone said I shouldn't and went out and bought a 96 cbr 600 f3, this thing just begged buy me it needs a chain tensioner and new plastics at some point because it went down but besides that its solid. Anyways I've noticed that the idle is somewhat jumpy like it fluctuates from 1 to 1.2k consistently is this normal? I didn't know because it's carbourated? Also I don't think the trip odometer is working maybe even the other odometer too, I'm not sure I havnt rode it yet

 

Hey, welcome to CBRF! An F3 was my first bike too. If you have your wits about you, you'll be fine. 200 Rpm fluctuations is somewhat normal, if it gets worse or is not smooth when you roll on the throttle, it may need a carb clean and carb sync.

You'll want the trip odometer to work as it'll be the primary way you'll know when to fill up.

 

The speedometer/odometer/trip meter are electronic. Meaning that there is a sensor on the engine block that determines speed and distance. If it's not working it could just be a lose connection. I guess you'd have to ride it to find out though.

 

im not sure on the cbr600 but on my kwaki a fluctuating idle points to a air or vac leak easy to check start it .spray wd40 around the exhaust clamps listen if the revs drop if not spray the carb to engine boots

 

On the trip meter, underneath the rubber reset button is a hard plastic stem and body. It can break very easily. I haven't been able to find a replacement for mine. I've tried every kind of glue I can find but nothing will hold that skinny long stem. IMO it wasn't built beefy enough. Iam thinking of having one 3D printed.

 

Thankfully cody iv just started to sort my gauge cluster out .neutral light.oil light .sidestand light come on but my Speedo,tachometer and temp gauge are not working so iv bought a f4 gauge cluster and I'll be using that out F3 has a speed sensor instead of tacho cable and looks fairly easy to wire up
