stored bike wont start


I have a KLR 650, 2000 that has been sitting idle in a dry garage for about 18 months. I finally have it in my possession again, and I am trying to get it running... It is not the first time it's been sitting a while, but I have never had a problem starting it.

Current state:
Turns over, fires and revs high with 'Start Gas' sprayed into the air intake. Will not idle. Initially it did start and run for about 20 seconds, some smoke, but all in all not too bad out the tailpipe. Unfortunately, it died out. Now, it only 'fires' off with the start gas. It sounds like it isn't getting fuel or a spark somehow. I let it turn over and over but nothing, it doesn't even 'kick' like it is getting any fire/spark/fuel.

Here is what I've tried:

1) Gas seems to be flowing, I've pulled off the filter and blew through it, doesn't seem clogged. I can see that it fills back up when reconnected. I can also feel suction on the smaller tube coming off the gas tank. Without the gas tank connected, I can hear hissing, like things are trying to be sucked through the system. Summary: I don't think it is the gas pump or otherwise.

2) I pulled the spark plug out, it was black, but dry. All in all looks like it could be replaced / cleaned, but didn't seem too bad. I scratched at it best I could to expose some brass without having a spark plug cleaner handy. As i said, with 'Start Gas' it does fire up, so seems there is a spark. Summary: I don't think it is the spark plug.

3) Fuel injection... or carb? Not honestly sure what is on the 650??? It is a carb, no? I have never had to touch it! Anyway, I think the problem may be in here, because somehow it does seem like I am not getting fuel. What should I check? One point, my choke cable is loose, but I have put it back in place, and I think it is okay, but could this be a problem? How to check? What should I 'pull apart' to investigate fuel delivery downstream of the major plumbing?

Thanks all! I'm only clueless because in general the KLR is so maintenance free it has left me without needing to keep up my 'wrenching' skills!!

Summer is here!

The carb probably is gummed up. Dump out the old gas in the tank and clean the carb and you should be good to go!

I would dump a can of Seafoam in the gas tank first and let it sit a day and try it again before I started messing with too much (you need gas in there too). Then see if you can get it running and get the Seafoam to do its job (clean the system). It's worked for me before. Amazing stuff, Seafoam. You can get it at any decent auto parts store. I believe it will run you a little under a ten spot.

I'd toss all the suggestions at the bike and see what you get.. Fresh gas, Seafoam, plug..

Start with the simple things first.. If that doesn't do it, pull the jets out of the carb and give them a good cleaning, but not until you give the simple things a fair chance..

You have gotten loads of great input from the guys but no one mentioned burning some sage leaves and chanting. This will help to remove any evil spirits that may be at play.

Otherwise I would do exactly as the people have advised.

Wow, great feedback! I'll go down today and give it another shot....

I am in Norway, so I hope I can find some seafoam. As for the gas, well, I pretty much left it dry, so as far as I can tell the gas that is getting in there now should be fresh...

I'll definitely be bringing along some Sage!!! I wonder if I ought to roll it underneath a 'lay lines' crossing ??

More upon return... (which if goes well, could be a while as I'll take a little cruise!!! )

From the description of the problem, your problem is the carbs and likely the pilot jet. Put your petcock in the "prime" position.

Carb indeed! Lacking Seafoam, I simply opened the top of the carb, pulled the jet and sprayed start gas directly on it, and the parts therein. The bike started up immediately afterwards... and 'thumped' like always. Love that sound!

Thanks everyone for the feedback.
