'07 klr 650 won't run without choke on

The bike ran great then sat for about two months and when I went to start it, it would only run with the choke full on. Took it apart and cleaned and blew out every damn oriffice, put it back together exactly to the setting as it came apart and no differance. Used new gas, new plug and now I'm going to tear it apart one more time. Totally baffeled ! I've played with carbs for years and this ones got me, and it's so simple ?

I have a supermagna and used fuel stablizer once and it wasnt fit it gummed my carbs up,ive cleaned mine often and it isnt rocket science,remove the tank airbox assembly,loosen up the boot flanges that hook the carbs to the motor(ones on carb)then remove the carbs,then the cables,choke and throttle,do not remove carbs from assembly(leave all 4 together)remove the bottoms and tops of a carb,removefloat and jet,then remove all the brass jets and clean them so you can see through holes,,blow out all the holes in carbs,and reasemble,works for me every time,about two hours to do,good luck

SOURCE: I have a 82 honda cb750f. The bike runs fine with

Standard jets for the CB 750 are 120's, popping and kicking are usually due to running lean which is probably why it runs great with the choke on as that riches it up. I've run 115's with no problem but 100's??? Maybe was trying for better fuel mileage when gas was $4.50 a gallon?

SOURCE: 79 gs550 - uh ohs in wiring...

When you reassembled the bike did you pinch any of the wiring harnesses? Trace the wiring through the bike and make sure everything has a solid connection between their respective power sources and activation switches. Alot of time bikes run wiring under the gas tanks so you need to make sure that you didnt cut anything when pputting it back on (if you removed the tank)

SOURCE: 81 Suzuki GS650GL only runs on full choke

Pull one of the fuel hoses off of it's carburetor, and stick the end in a clean can or bottle. Turn on the fuel tap--you should get a thin stream of fuel. If it just drips, you need to clean the filter screen just above the fuel tap bowl. Hope that gets you running well.

SOURCE: yamaha 125 grizzly starts and idles when choked but dies when acc

Take the carburetor apart again, remove the main and idle jets and idle mix screw, plus the float and needle valve. The main jet holds an 'emulsion tube' in--look inside where the slide valve moves, you should see a short brass tube projecting out of the bottom. Carefully push down on that tube with a plastic rod or wooden dowel, it should drop out the hole where the main jet was. Chances are that the tube is dirty and needs to be cleaned--look carefully at the series of small holes drilled into the sides of the tube. These small holes deliver air which is mixed into the fuel passed through the main jet. That air comes from a small hole just inside the intake side of the carburetor. The long needle that sticks out of the slide bottom controls low to mid-range speed fuel-mixture. Check that the 'C' clip on the top end of the needle is in the center groove and that the retainer spring is pressed down the 'C' clip. Now soak the whole carburetor with spray cleaner, then blow out all passages with compressed air. Don't soak the rubber-tipped needle valve from under the float. On reassembly, set the idle mix screw 1-1/2 to 2 turns CCW from CW stop. Adjust for best idle after you get it running and warmed up. I hope this long winded explanation helps!

My 2005 KLR 650 is overheating but I'm not sure of the cause. The metal box under the seat is incredibly hot but I don't know its purpose so I was hoping you can give me some ideas

hiya

This is normal, my 87' would do the same thing. There are two mod's all KLR owners should do...
1. Install an overide switch for the fan, mine is a three way auto.off.on
2. Cut off switch for the lights.(Great for crawling around off road)
The overide switch for the fan helps keep the temp down below the red. Now, I have never sat in a traffic jam on a 100 day, but it has helped with everything else thusfar

hope this helps

I have an 2006 klr650.. The bike will only run on choke and will not idle on its own. If you use the throttle the engine stalls out. the bike has not been ridden 3-weeks. Any help would be appreciated...

Had the same problem on a 2008 KLR 650. It would run but only when the choke was on and no added throttle. Add throttle and it would die.Took the carburetor apart and reinstalled is several time before I found the issue. One of the very small return tubes running through the carburetor was clogged. It is so small it didn't even look like a return tube in the carb. It seems to have failed during storage and gas varnishing in the tube. Carb cleaner and compressed air finally cleaned it out. It looks like a jet but it isn't and it does come out with a straight blade. Make sure it fits so you don't damage it. This is not the main jet. but it is next to it. Found it looking like a solid and not even a tube. Again very small. This fixed the issue and it runs great again. The issue is from bad gas. Don't forget to add Stable or some other additive to keep the carb from gumming up or getting nasty inside. Problem #2, broken Choke cable nut. The factory one is plastic and will crack under heat cycles and time and well just working on the carburetor. Buy this metal one to repair: http://www.steadengineering.com/product.sc;jsessionid=D6F227A0DCEF8E87895CC3C92FFBE743.m1plqscsfapp06?productId=2&categoryId=1. Bought one and yup you will never have another trouble with it again. Made by Stead Engineering . Worth the money for get piece of mind.

Yamaha TW 200 starts but won't run.

If the bike has sat for a long period of time without being run - the gas that is sitting in the carb(s) will shellac.. Then the carb(s) would need to be cleaned and "rebuilt"..

I have a 2006 klr 650 with 2450mile on it. Today I went to start the bike and nothing. At first the head light came on, then i pushed the starter button and everything went off. I check the battery and it...

The battery is dead. I suggest an AGM battery from bikebatts.com. The dual sport bikes especially can use those because they don't leak when you fall over in the dirt.

By the way there are some good dual sport sites like advrider and thumpertalk, and some good klr forums out there too.
