Carb Newbie...

Recommended Posts

hey when i bought my bike the guy messed with a white plastic knob under the carb and small screw facing the shifter side of the motor on the very bottom of the bowl. I (obviously) know nothing about adjusting the carb but my idle is a little too fast. I tried turning the white plastic knob but it doesnt want to turn. Question is is that white knob the idle adjustment or am i not messing with the right thing... sorry for the probably obvious question but i cant quite find what im looking for using search:confused:

I hope you get your answer- I am dealing with lean running popping on deceleration and I turned that knob on the carb and it has improved my lean situation greatly but didn't really raise idle like I thought it would.

white nob will not fix a lean condition, has nothing to do with mixture..it adjusts the throttle resting position.. it should turn, clockwise to idle up, counter clock wise to idle down.

+1 :thumbsup: Also adjust it when the motor is warmed up.

it should turn with only a little resistence,,unless yours is seized, rusty,old 01 probably,etc..might want to try some wd40 or the like with the extension tube thingy, and spray it from the other side, give it a light tap...

      Hey all, 
      I'm looking at buying a 2004 Suzuki DRZ400EK or at least I think it's an EK according to Vin lookup websites, but it does not appear to have a kickstarter. I was told the bike was owned by a motorcycle dealer and that it has a current green sticker, and a California license plate but has not been registered for the streets since 2011. I want this as a dual sport but am not clear if the fact that it already has a plate means I am good to register it or if maybe they took away the ability to register it after it was plated, California loves to do that kind of stuff. Since the bike was owned by a dealer I would think they were up on the latest regulations in California, but who knows. Can anyone add any insight as to what I should look for on the bike itself like the carburetor, model numbers etc? Or do I just try my luck at the DMV?

      Hi,
      I have a 2003 DRZ (actually a KLX400) and the head tube bearings are shot.  I ordered a new set to install but I'm wondering if anyone has any recommendations on other parts I should replace while I have the front disassembled.  I was thinking about new rubber fork protectors, but are there other things that wear out on the DRZ front ends that you can only get to when disassambled?
      I also broke off a replacement key that I got for the steering lock.  I must have been made of cheap pot-metal.  Should I just remove the whole lock mechanism?
      Any tips or tricks for getting the old bearings out and the new ones in would be welcome!
      Thanks!

      Hey Guys,
      I recently bought a 2003 DRZ400S and thought it would be a good idea to check the valves clearance etc . I timed the engine on TDC with the magneto mark aligned as per the manual but I find the cam timing slightly odd. The arrows pointing upward are on the 1st and 15th pin as they should but with the magneto timing mark aligned they are not perfectly straight. Same goes for the arrows that should be parallel to the cylinder head casing. Is this normal or should they be absolutely perfect ?
