Puch MV50 back together after recent seizure (see previous blog). Seizure suffered by bike not owner. Although I have obtained a new barrel and piston Jim Lee (well known Puch expert and motorcycle raconteur) advised I could try to carefully file down the high spots on the old piston and reuse. So I have done this. I read a story the other day that if you have a spare for any vehicle part the original will not go wrong. I am banking on this.
Took the bike out yesterday with great trepidation as I don't know what the cause of the original fault was. My worry was that the crankcase seals had gone allowing an air leak into the crankcase, a weak mixture and consequent overheating. Jim doesn't think it is the seals otherwise it would be more difficult to start. I have made sure that there are no air leaks en route from the air filter to the cylinder. When the bike seized I was using, for the first time a Miller 2T oil supposedly for older and vintage engines. For the trial run yesterday I went back to a modern two stroke oil.
What happened. The bike started and sounded a little strange for a short while but this settled down and I went for a run of about eight miles keeping the speed to around 20 mph with no obvious mishap. The plan is to repeat this slowly increasing speed and distance if there are no further calamities. Blog to be informed

No, not your blog of course. I concede that your posts are succinct, insightful, humorous and well worth reading. That is why I would appreciate it if you could spare a moment to cast your eye over my efforts and let me know how I can encourage people to read it. On the other hand it may be the most boring blog, someone's has to be.
