I have to admit I've been pretty slack about fork maintenance, but I just had both tires off to replace with new Commander ll's. I was surprised at how easy it is to remove the forks actually. I didn't completely dismantle them this time, just drained the old oil out, stroked them about a dozen times, and then added the required amount to bring the oil up to the level specified in the service manual. I will tear them right down at my next tire change. You wouldn't believe how black and thick the old oil was. It makes all the difference in the world with new oil and new tires. My stem bearings were good also. I can now loosen my grip on the bars at any speed and it no longer begins to shake. I attribute most of that to tires. If you're on the fence about doing your forks, fear not as it's pretty easy and makes a big difference.
