Didn't work!

[Dave Daniels]

If I remember correctly, it just involves removing the shifter lever, prying out the old seal and installing the new one. Correct me Charles.

Guy,

   You say that after riding 80 miles you have an inch of play in the chain. How much play are you setting into the chain to begin with? You should adjust your chain so there is between 1" and 1 1/2" of play to begin with. If you set the chain too tight, you will wear out your chain and sprockets in a hurry. Causees the chain to run hot and can ruin a chain very quickly. Too loose is better than too tight when adjusting a chain. I don't know if an over tight chain will induce a vibration or not. Since it doesn't happen until 5 or 10 minutes after you've been riding, is it possible you have a bad tire? Possibly out of round or balance and after the tires warm up, the problem becomes obvious?
   The oil leak sounds like the usual leak around the shifter shaft. That seal is notorious for leaking. Fairly easy to replace, though it's been awhile since I've done it. Charles is an expert on this problem and can jump in with instructions.

I also still have the problem with the chain tension... I set the tension, nothing on the rear axle moves and after putting 80 miles on the bike, I have about 1" of play in the chain. Oh, and I now have a new oil leak from somewhere under the front sprocket cover... This sucks. I don't think I'm cut out to be a shade tree mechanic.
