A non-zero answer

I haven't worked on the bul since September!  Sheesh.  I wish I had a good excuse.  I don't.  I've been lazy.  With the 3rd car back - it's really hard to get out to the garage and do work, since I have to move so much stuff around.  But, I'm tired of looking at it in pieces, and I'm afraid that I'll start losing parts.  So, I'll try to do little stuff again.

Today's little stuff was getting the cover back on the clutch plates and shifter.  I had some Yamabond 4 left over from when I did the valve cover gasket on the BMW330i.  Basically, it's a lot like form-a-gasket, but better.  I used small amounts of it on both the case and the clutch cover, to both hold the paper gasket in place and fill in any areas in case of warpage.

While I had the case cover off, I gave it a light polish with metal polish and a buffing head in the drill, as well as colored in the "Bultaco" emblem with Krylon paint marker.

After about 30 minutes of work, here's what it looked like.


I've also been noticing a small drip underneath the bike every so often, so I checked that out as well.  There was a crappy paper/rubber gasket on the transmission oil drain.  Suckage.   I dug into the parts box, and found a copper crush washer that was the same size.  I put that on the oil drain bolt and tightened it up nice.  That should stop that leak.  I also re-installed clutch drain plug, and luckily the new aftermarket one I ordered came with an aluminum crush washer.  I hope this stops all of the leakage around the bottom end that I used to have.

Finally, I dug the shifter out of the box of things that were chrome plated ages ago, and reattached it to the bike.  Maybe next weekend I'll fill the transmission and clutch up and see if there are any leaks.  Hopefully not.
