Hi Everybody,

I have a 2009 KLR 650, has around 11250 miles, rode 450 miles and left it in the garage. 2-3 days later I tried to start up it won't start. It has cranking noise but the engine would not turn over. First I thought, probably I have to put some gas. So I bought a gallon of gas, poured it in, still it won't start. I checked the kill switch, it is in normal position. The battery seems fine. The bike is in neutral. I am not sure what to check. Anybody could give me some ideas please.

Thanks.

Don't get, "cranking noise but the engine would not turn over."

To me, "turning over," is the source of cranking noise.

That said, you need spark, a combustible mixture, and compression to start and to run the bike.

Got spark? Got compression? If so, you need only a combustible mixture. STARTING FLUID can provide that element; be careful with fire extinguisher handy.

You need to check to see if fuel reaches youor carb; open the drain screw on the float bowl and see if any gasoline is present. If not, you may have a petcock problem. If so, and it still won't start, you could have clogged jets; your carb needs a cleaning.

Anyone familiar with engines accessible to you?

Well, I asked a guy to come over and take a look at it. He said, he will come. I am not familiar with the engine and I don't have the owner's manual. I need to find a manual online. I will try to check the things that you have described. One question, what causes the clogged jets? The bike was not sitting in the garage and the gasoline was not that old either.

Thanks for the suggestion.

I would look at the battery connections as well. Mine did a similar thing not too long ago and turned out that the cable terminal was not quite making enough contact to start but everything else seemed normal. Good luck!

Try the kill switch a few times anyway.
Sounds like it's getting gas as it has already run fine.
A vacuum leak could have started as these Thailand
rubber components seem to deteriorate a bit early.
If that's the case your gas is automatically shut off.


On that note I took out the diaphram in the petcock and
put it back together n' capped off the vac- line. In fact, removed the
entire octopus and capped everything off.
Then, I disabled every safety switch on the thing ie:
clutch interlock, kickstand, and neutral thingie.
Just like our dads and granddads, I have to check the neutral light,
sidestand, and make sure to turn on the gas before pulling in the clutch (habit)
and firing it up. It's just less things that can go wrong out in the middle
of nowhere or the driveway that can leave me stranded.

Ride fun and often,
Cheeeeeeeeeeeeeeeeeeeeeeeeeeap

One question, what causes the clogged jets?
Good question.

A number of things can occlude jets. One is deteriorating, aging fuel; especially now with the politically-motivated ethanol infusions we must suffer.

Then again, there are just plain ol' li'l bits of TRASH that now and then enter the sanctuary of our fuel supply system; could elude the petcock standpipe strainers, any aftermarket in-line filters, and wind up clogging one or more jets.

Even THIS has happened: The cork-like or rubber-like or whatever-like gaskets in the petcock assembly vicinity DETERIORATE, flake off, and merrily glide down the fuel line to the carburetor float bowl, where they raise their own demonic havoc.

Ain't exactly CLOGGED jets, but . . . fuel contamination through moisture can be a problem. The main jet is the lowest (in elevation) jet; water is heavier than gasoline; thus . . . a pilot or idle jet may suck up its sustenance and the engine idles fine, but . . . open the throttle, crack the butterfly valve, create manifold above the diaphragm raising the slide and the needle and . . . the main jet sucks up only incombustible WATER, resulting in a stall or flame-out.

From this rambling, purging your float bowl, to get rid of trash (if you're lucky) or contaminated fuel, and re-fill with the best gasoline you have on board (from your fuel tank) isn't a bad idea, when fuel contamination is suspected.
