I have:

'01 S

Hotcams in/ E exhaust cam

Dynojet CV carb

12.2:1 base gasket

Full Open muzzy exhaust

15/49 gearing

Kenda k270 rear / IRC ve35 front

Battery and unnecessary junk removed

kicker kit

The 98 YZ400f I rode last weekend had:

Hydraulic clutch

Sand knobbies (Dunlop 7??)

Stock exhaust

Optimized jetting

Race tech suspension front and rear

Excel gold rims

The difference I noticed on a sand track was the:

Weight- The bike wheelied easier and was more "flickable"

Throttle response The bike wheelied easier and needed less throttle "turn" to get power down.

Landing from jumps didn't kill my back and legs.

The bike revved out farther and pulled harder.

The YZ 400 has an FCR carb, ,now I know what difference these guys talk about when going from a CV to an FCR. I WANT ONE!! That and racetech suspension.

Overall, the Yamaslop kicked the drz butt for ridability, ease of handling and it was less fatiguing. It also tracked straight and didn't wallow like the drz. But I love the drz as I can ride it on the street! :)

Burned: With the motor mods, the YZ400 felt alot stronger than the drz. Will the FCR wake up the drz enough to be competitive power wise with the stock yz400? I know the sand knobby and the 25 lb weight difference made some difference, but man that yz was strong!! wheelied on command.

      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 ?
