Difficult to start bike in colder weather / first start of the day

Recommended Posts

Hi all! I have a 2006 S with about 16,000 miles on it. the problem I'm having is that whenever I try to start it in the morning (night time lows at about 55 F) it will take 4-5 cranks of the starter to get it running. It will usually idle very low then immediately die after after the 2nd or 3rd attempt. Giving it gas seems to make it worse, choke seems to make it worse. I will use the choke to warm it up once I get it going but it dies with the choke on untill it is partially warmed up.

Your possibly very lean (partially plugged pilot or simply too small jet) and the "choke" on the Mikuni is really just an enrichment circuit that adds more air along with fuel so can make it worse if the fuel isn't flowing correctly . Besides verifying valve clearances , which would've been showing up over a period of time as it got worse and worse, if this issue just showed up it's likely not valves unless there is something bad going fast .

      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?

      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!

      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 ?
