Stock cvk problems

Recommended Posts

Fellas, I have been running the stock carb for 3yrs now w/o any problems (besides the obvious limitations). I removed the airbox, sealed the openings to the crankcase and intake end of carb and washed my bike. After re-intallation the bike would not idle, only when the trottle was open would it run. I disassembled the carb and couldn't find any dirt/water. What do you guys think could be my problem?

Thanks for any help you may give. Cree

We had a similar problem. You need to take your carb completely apart and clean all the passageways and parts. Then it should run fine. If not, check your plug cap for water condensation. Good luck.

PS - if you've never taken it apart before, beware of internal springs and catapulting parts! :-)

I can take a guess. Maybe some carb vent hoses got pinched when you put things back together, or maybe they are blocked by grime or soapy water. Maybe the carb connection to the engine got bumped and is now loose creating an air leak.

It sounds like one of the jets for the idle circuit are plugged. I had that happen once, it sounds like the same result as you are having. Carb cleaner alone did not work for me, I took a sewing needle and poked it into the jet to break whatever was in there free. Aren't those jets right there at the intake side of the carb. Maybe you didn't seal off the intake as good as you thought. This sounds most likely to me.

      Bike has been taken care of. Only damage is 2 small scratches on tank from leaning against it with belt buckle. Has been stored outside, but covered.

      The radiator fan isn’t starting up, even though none of the fuses or connections between the battery, fan and radiator are bad. I figured it has to be the fan relay, but none of the diagrams I’ve seen matched up with the wires on the bike. Does anyone know where the fan relay is for this bike?

      Hey Thumpers,
      I am swapping forks and need to know what triple clamps / tripple trees will also fit the 93-96 KLX650r forks. Through some research it looks like KLX300 and pre 09 KLX250 clamps will also fit. But given the ambiguous name of these parts (triple/tripple trees/clamps) doing a search to get good info is difficult. And many of the clamps I am finding for sale are rather expensive so just want to make sure I am getting the right part before pulling the trigger. Thanks for your help!

      My Klx400 is a great...fun bike to ride off road with a few highway runs in between trails, but I felt I needed something different if I was going to ride the highway with the occasional off road excursions......so now I own a 2002 klr650. What a world of difference between there bikes, but I believe that between these 2 bikes I now have the one bike I was looking for... if that makes sense.

      Hello guys. I just got a while ago a KLX650 1996 with about 34,000km. 
      I was in the process of adjusting the valve clearance, they were really out of tolerance so I ordered new shims and when removing the camshaft I had the 2 tensionned mechanism removed (automatic camshaft tensioner, and the spring tensioner bolt).
      I am now in the process of re-timing the camshafts but I'm not able to line up the EX and IN line properly, I always seem to be half a tooth off when positioning the crankshaft at TDC.
      Could it be that i've had the lower chain come out of timing? I might have turn the crankshaft with tensionners removed... 
       
      I am including pictures of the camshaft marks and as you notice camera angle makes a difference but what are your thoughts?
      If i cannot put the marks right on spot, is it better to have the intake valve open half a tooth before, or half a tooth after? and what about the exhaust?
       
      Thanks
       
      Sebastien
