Cam shimming

Recommended Posts

I installed my new E cams. Do I need to start it up and let it run and then measure the tappet clearances, or do I just bolt it in and measure then. Right now the exhaust side has a 318 and a 315 shim, and they both have a .007 clearance. The intake side has a 280 with .006 and a 282 with .004.

rotate the motor over a few times by hand

Always turn over by hand after doing anything with the cams/valves, I usually do several full rotations before measuring. I listen and feel for anything unusual during this time.

I turned it over by hand a few times, and they did change a little. The exhaust is a 318 with .008 and a 315 with .007. The intake is a 282 with .005 and a 280 with .006. Should I ride it like this for a day and then check it again, or do I need to even things up first?

I was hoping to get some shims before everything closes if I need them. So should I ride it like it is and then check after a ride, or re shim now?

I'm looking to buy the hotcam setup for the intake, and exhaust. I am not sure if I will need to buy an entire shim set online (what a ripoff! found it for 90 bucks so far). Where did you guys get shims, and what quantity did you have to buy them in?

      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 ?
