extra or important?

I changed my handlebars recently and when i was putting the throttle back i noticed 2 cables hooked into the handgrip but one was just ran through my bike and was not attached to anything but the other was attached to the throttle. Do i need this other cable. I rode to work the next day and everything seemed ok.......

the throttle is a push/pull system.. you can get by with only the pull side connected (to open throttle), as the return spring should close the throttle. the 2nd cable is for closing the throttle when you return the throttle to a more closed position.

its probably primarily a safety item, so that you can always close the throttle if one of the cables breaks

If I understand correctly what your asking the un-attached cable is a return cable. The one cable pulls the throttle linkage to accelerate the engine. The one not attached draws the throttle back to idle. It may be ok to ride a little while like this but I would rig it correctly, a stuck throttle can be a scary experience!

Just want to leave this note for anyone looking at this later...

It can sometimes be impossible to stop an engine (gas fueled) running wide open by shutting off the ignition.

Just in case anyone wants to risk a stuck throttle.

Reattach the darn cable. A runaway engine is problematic (to say the least).

I have a buddy that bought a brand new quad 'bout 15 years ago... first time he rode it, after about 15 minutes he cracked the throttle wide open. it stuck. since the machine was new to him, he was fumbling for the kill switch about the time he hit a tree around 50 mph. totalled the machine and put a hurtin' on the driver (who did recover fine). turns out someone in the factory dropped a pen clip down in the carb.

one of my good buddies was riding one of my dirt bikes (ok this was a good long time ago) I didn't have much $ for repairing stuff so would skimp... think the bike was around 1980 rm125 (know it was an airhead with twin fox shocks hehe), didn't have a kill switch and I neglected to put one on... anyways my buddy watches me do a hill climb (used to have a gnarly hill right next to my apartment) and wants to do it, anyways he biff's halfway up, somehow got his leg in between the rear fender and wheel... right grip buried in the dirt... bike running wfo in maybe 2nd or 3rd gear... took me maybe 10 seconds to get to him and pull him out... you can bet he had a nasty bit of knobbie rash... unfortunately the bike had a real new rear tire...

anyways don't be another "story" about an engine running wfo and having piss run down your leg. I would recommend fixing the cable very soon, bro!! stuff can and does happen!

So when i found it, it (the secondary cable) wasnt attached to anything on the bike it was just routed through the bike and hooked into the throttle. It seems like theres nothing to be pulling it back to the idle position from being pulled open. Is this how it should be? or is it supposed to be attached to something near the engine? As ive said before im not very mechanical but open throttle sounds scary so i wanna fix it but the right way if it was not before. Help me out
