  1. There is always a bright side to a story: I was smart enough to buy all the parts needed for the job since the last rebuild, connecting rod, piston kit, seals etc., so hopefully I'll have it running like new for our big annual meeting with Mick.

  2. Disaster: Just for fun I took the piston from the connecting rod, top bearing is done and yep the rod is corroded too, so crank job.

    I always use Shell Ultra that is suppose to be ethanol free. The transmission side is just as new, but the crankshaft side is very dirty with what look like rust mix with oil. There as been big change in temperature in the last few month especially in the period I was out of town, but I would have never believe that it could such damage. When I change the oil in the transmission I only ran it for a few minutes, probably long enough to '' spread the disease ''.

  3. Yesterday I took my B model out to make the final prep for today's  friendly competition. I could not crank it, jerk it front and back it did not seem to be stuck, so I tought that the crank was the problem. After all it did start great about 3 weeks ago when I changed the transmission oil. After removing the side cover, everything looked ok, and I could not find the cause of my problem, took the clutch out, all the separate gear where free appart from the one on the end of the crankshaft.  Than with the sparkplug out I tried to turn the motor: horror it WAS stuck. So head and cylinder off ( it was not stuck too hard ) I found water in the base, enough that the bottom of the cylinder is pitted. There was no water in the oil of the transmission ( I was not surprise by that ). It had good compression, no leak between the base and cylinder and the gas that I use is always fresh and clean. So where does that water came from, the only way it could get in the base is by the exhaust witch is in my opinion improbable. The exhaust would have to be full of water. Any idea ?

  4. I made an extension for my 250 ( not off the shelf ) a few years back, and I did not felt such a difference, even if I oiled the cable until I followed JonV8 advise. I replace the cable with a new Venhill and oiled it with WD40 every ride. At our last TS meeting a few friend tried the clutch and the general comment was it's almost as light as a modern bike clutch.
