Replace drive chain?

Recommended Posts

The drive chain on my DRZ S is 5 years old, but only has 2,700 miles on it. The chain side plates look fine, never has had any corrosion, and the chain feels fine with no tight links or other items that seem wrong. There is no visible wear on the chain or sprockets.

The only issue is that I can see some o-rings have checking (cracking) on them. It seems that during this bike’s long storage, the o-rings dried out some as it seems to me that the previous owner didn’t keep the chain greased the way you should for a multi-year storage. Anyway, that’s the only item that makes this chain look different from a brand new one.

OK, I bought a new one from TT along with the new tires, but now I’m wondering if I should save the new chain as maybe this one has more miles left on it. Does anybody here have an opinion on whether checking or cracking of the o-rings on an otherwise perfect drive chain is reason to replace it? I ride far away and all alone. The last thing I need is a broken chain, but I also don’t want to toss a good part to replace with an equally good part.

Input? Thanks.

If i was in your position I would put on a new chain if only for piece of mind. To me, chain and sprockets are items whch shouldn't be skimped on, especially if you ride on your own.

Also, if the chain was to break it could damage your engine cases which would be very expensive to repair, but this could be saved for a relatively cheap part.

At the end of the day it's your choice, hope it works out for you :)

You've already got the new chain, put it on. Why tempt fate?

Your old chain is fine to run. The "O" rings seal in the lube and seal out the dirt. Once the seals go bad the chain will go bad quickly but it will give plenty of warning. The checking you see may be significant, or maybe not. I would have to see it to know. Just take care of it as always and when you see tight spots or the chain seems to change slack as you spin the wheel - then it's a gonner. Depending on how you use the bike and maintain it, 5000 miles is not hard to get on a good chain. My street bikes go 30,000

      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 ?
