Here's my Car Talk question of the day...

Hi All,

So went out to start my bike today for work and brave the 94 degree heat but the my niner acted very strangely...

The bike will start up but I need to rev the throttle in order to keep it running, and not just holding the throttle on as the RPM's will slowly drop until the engine eventually shuts off. The bike sounds very muffled and almost as if the engine has been flooded (which I know it is FI and would not be the case as I didn't do anything to flood it either). The bike literally sounds like it is sick and dying and won't stay alive.

A couple of days ago I changed the clutch cable and levers but I don't see why that would be my problem.

Any help would be greatly appreciated as I am slightly mechanically inclined but I don't even know where to begin with this one.

Thanks guys,
Brian

Also to note, when I installed the clutch cable I did the duct tape and pull method to route the cable (unsure if that could've knocked anything around) and I do run a PCIII

Might have knocked a vacuum line loose? Just a guess.

Others will chime in, but its sound like a familiar problem with the PCIII.

Hmm I'll check out after work, vacuum line makes sense, maybe something is pinched...

To test if it's the PCIII would I just throw a zeroed out map on it and check that way?

Is this the first time you started it since replacing the cable?

Regardless, the number one rule when having just done something and a problem crops up: whatever you did caused it!

With the nearly right angle bent steel tube the stock cable has it's almost inevitable that it caught on a wire or vacuum hose and either disconnected it or pinched / cut it. You can tell that is happening when while drawing the new cable through it suddenly stops or requires much more force to continue. Voilà, a problem! Tilt the tank up, prop it in place, and inspect everything anywhere near the clutch cable: it runs past quite a number of critical parts, particularly vacuum tees and the ignition coils. Chances are good that you will find the problem. Hopefully it will just be an easy reconnection and you're back in business.

If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.

Ignition coil trigger wires is a good thought as they are pretty small gage wire.

Thanks for all the all help guys, Marylandmike, you're right, it was one of the wires got knocked off. Up and running with a new map, clutch cable, levers and just hit the 30K mark driving into work this morning.

Rob called it. Glad you got her back and running right.
