Hey folks,
First time forum diving so go easy on me. I am one of the few RC51 riders in SoCal since we are in an era of R1s and CBRs and whatnot. And we all get a lot of good looks when we ride this beast.

Well I have run into a snag. As I am not a grease monkey, I am having an issue with starting my bike. Now I have had my ride for over three years. It is a 2002 and has been very good to me. So here is the deal:
Turn key to on, prime the fuel tank, bike is in neutral-double checked it by rocking it so we are good there. So far all the start up procedures are in place and good to go. Now I go to start the bike and nothing happens. It acts like the bike is in gear, you know you push the button and nothing happens. Just like that, you see. I looked around and even found a few fuses and all was good to go.

So what do I do now? Help me Obi-one-kinobi, you're my only hope. Hahaa. But for reals, I need some 51 love over here.

For whatever reason, your starter relay is not actuating.

I would check your side-stand switch first as it most often fails over the clutch lever micro-switch.
Check the clutch micro-switch next.

The engine stop switch can be problematic as well, but you said the fuel pump primes, so that is probably not a problem.
Since your neutral light comes on, the neutral micro-switch appears to be working.

Here's a diagram of the circuit involved from the service manual.

With that being said, could it be the starter relay itself? Or if the starter relay went out, would the fuel pump not prime?

Just another idea. Keep us updated.

It could be a problem with the starter relay.
The main 30A fuse is located in the starter relay housing.
If that blows, no current will reach the starter motor.

When you press the start button, do you hear the starter relay even click?
If not, your start button may be the culprit.

I think SubSailor nailed it. It could be the starter relay. There's a 30 amp fuse next to the starter relay that should be checked as well. (Don't confuse it for the spare 30amp fuse that Honda has had the foresight to include. :) )
The starter relay is the one relay that can't be interchanged. You either have to test it, or exchange it for a known good one.

Of course, you can jump across the relay to bypass it to see if the starter motor will engage.

One other thing, make sure your fuses are all good in the little fuse panel on the left side of the bike.
Use a dab of dielectric grease on all your electrical connections.


btw cdemps, I'm not aware of any "grease monkeys" around here. :cool:

You said you checked the fuses, but again check the fuse box on the state of 10A Fuse F.
It's the 10A fuse in the diagram I posted in post #4.
That fuse affects starter operation and ignition. If it blows, no starter operation.

Gents,

I appreciate the good info. I will check the starter relay. I will have to locate that thing on my bike but from what you all are talking it does sound something as simple as a fuse.

And no offense meant on the term 'grease monkeys.' I will give you all a heads up on what happens.

I think I am a fan of this forum stuff. Good lookin' out, gents.

Til then...

^ It's actually underneath the tailsection. You have to remove the plastic tailsection and you'll find it attached to the sub-frame. On the left like Polarbear said.

Thanks fellas. I will check on it and hope that the Nicky Hayden Gods are with me. Will keep you all posted.

Well the Gods were not with me this time, gents. I took off the rear cowl and checked out two fuses both of which are 30s, in the immediate area of each other, and both are still good. I even tried restarting the bike just in case it would work but no joy there.

Any other suggestions?

JD9... If he is in your neck of the woods - Maybe you can give the man a crash course in person ? It sounds to me like it is either the starter relay itself, or the ever famous kickstand sensor issue.

It is not the tilt sensor in my opinion as the fuel pump IS priming... so he says.

cdemps,
Are you, or are you not hearing a " CLICK " when you hit starter button with everything live and ready to live ???

Duckhunter,
I am not hearing any audible 'clicking' once I push the start button to fire up the engine not to be confused with the noise of the fuel pump priming.

Where would I search for the famous kickstand sensor and how would I know it is faulty?

Have you tried starting it with the stand up ?

UNPLUG the wire harness going to kick stand. Just use a jumper wire to bridge the gap... bypassing the switch.

If not... replace the starter relay with new.

Just to cover the basics (because it's happened to many motorcyclists in the past):

Is the stop/start switch set to the "run/on" position when attempting to start the bike?

Is kickstand up?

Did you try holding the clutch lever in while starting in neutral as well?

How old is the battery? Are the battery terminal leads secure and tight?



I'm sure you'll be able to check off all of the above items but just in case...g'luck!
