Hey guys, I've run into a bit of a brick wall currently with the bike so I'm looking for some help.

In the 3 1/2 years I've owned my bike it's never given me a day of trouble, until this year. There was a small situation a few days after I took it out of storage where it stalled shortly after I started it after it sat in the sun for a few hours, and it took a second to fire back up, but then that didn't happen again that day.

A couple weeks later I go to leave work, the bike had one again been in the sun for a few hours, and it refused to start. It spit and sputtered and would occasionally fire but then die right away. I had to roll it into the shade for a bit and give it a ton of convincing (multiple attempts while giving it some throttle) and EVENTUALLY I got it to start and run smooth. Rode it home, put it away.

Took it out once or twice after that, no troubles, until one day it sits in the sun again for a few hours, and it took an hour and a half to finally get the thing to start and idle. That day I ride it home, and it threatens to stall every time I take off after sitting at a stop sign for even just 5 seconds. I get it home and it refuses to start again.

After some talking of the 600RR.net Facebook page, I think I've got it down to a battery (tested it as hot bike/hot battery = no start; cold bike/hot battery = no start; cold bike/cold battery = fires right up and runs smooth) So i buy a brand new battery. I put the battery in, and it fires right up. It sputters a bit but smooths out, I figure maybe there's some residual fuel in the cylinders from the running issues previously, but I think I've got it licked.

I go to ride a few days later, complete refusal to start, I notice it's now blinking a code, 1 long, 8 short, code 18 Cam Pulse Sensor. I pull the fairing, disconnect the sensor, hook up a multimeter and turn the bike over, I get .2-.4 volts when it should be between .7-1.5v at least. So I order a sensor. Today I installed the new sensor, no change at all.

The fuel pump is priming, so no issues there, I tried clearing the code by jumping the DLC, still no start. I'm totally out of ideas and totally stressed out. This came completely out of nowhere and I have no idea what the issue could be at this point. I do have a PC3 hooked up, but that powers on just as it should judging by the lights, and that wouldn't cause a code 18. Somebody help!!!

First, what's the voltage on the battery? Brand new means nothing when you're having issues. Make sure you have at least 12.8v or higher. Low voltage will fry your PC3.

Second, how old is the fuel?

Third, check your main ground wire for corrosion and tightness.

If none of those pan out I'd zero out the PC3 fuel map or disconnect it all together to eliminate the PC3.

Also, did you check your air filter for rats nest? They simply love our bikes air box for nesting.

I have not checked the voltage on the new battery.

The fuel is brand new, even has a little bit of Lucas fuel cleaner in it.

All connections at the battery appear to be clean and free of corrosion.

Have not checked the air box.

Even with all of that in mind though, why would the bike throw a cam pulse code if any of those things were the issue?

Venom did you read my whole post? I just replaced the CPG tonight and the problem still exists. That's why I'm totally confused.

Ahhh ok now I read it all. What I would do though...

1. Did you rechecked the CPG? It should reach 0.7 V @ 68F or 20C (or you can put it in the oven just to reach that temp).

2. Stripped PC3 just to rule it out.

3. Inspect the wires... not the one that you just replaced but the ones on the main harness.

That's all I can think off as of now though.

I'll recheck it tomorrow. And if that's registering as it should I'll be stripping the fairings to check the air box, then pull out the PC3 and see where that gets me. I'm just so frustrated by it all.

Found the problem. ****.





Anybody have a spare harness for an 07 without ABS?

Well I was close. Damn little vermin love to chew on wires! I've had to rewire my lawn mower more than once.

If anyone has one laying around I would be interested! I'll check the numbers on the ECU tomorrow.

I've had to rewire worse so don't be so quick to write it off. Start separating the harness so you can get some good wire while you try and find a new one.

Definitely fixable. BTW, low voltage won't FRY the PC.
Actually, I destroyed, fried, damaged beyond repair, my old PCIII from trying to crank my bike on a battery that was @11.0v and was confirmed by Dynojet. My warning should be taken seriously. Check your battery voltage regularly.

There seem to be some decent harnesses on eBay running $40-$100. Some do mention cut plugs here and there but some look to be in good shape and intact.

Real good reason to not keep bike outside for long term storage...

This can happen in an inside enviro as well.

Maybe, adopt a cat or three, and garage bike next winter?

The rodents WILL returnnnnnnn........!

Some people don't have an indoor option. I know I kept my '04 garage kept for the first 10 years. But changing life circumstances left my girl out in the cold for awhile.

I will say I've had rodents chewing the wires on my lawnmower the past couple of years. I got frustrated and for whatever reason started spraying all the wiring with silicone spray. Short term seems promising as they have not chewed anything recently. I've also heard peppermint repels rodents.

You should at least put some steel wool inside your tail pipe and air intake so they can't build a nest inside.

The bike is kept technically outside but I bought a really nice shelter for it. It's a 6x6 Shelterlogic, just big enough for the bike. Once this is all taken care of I'll be packing plenty of mothballs and dryer sheets under that tank cover. I'm going to call my insurance company as well, because I have full coverage with comprehensive and they apparently cover rodent damage. So if I can get a brand new factory harness installed for the price of my deductible, I'll be happy.
