Arrived YS 60 FSH motor disappointed me a bit, that was made successfully bid in Yahoo Auction at 2,980 yen without competitors.
There exists no worn away evidence outside probably with very short period of time operation, but the ringed piston has apperent shinny spot at exhaust angular position also at opposite side meaning that the motor had been operated in very critical condition, too lean mixture loosing main needle valve setting. As a common sense, Ringed Piston has enough tolerance between the cylinder wall compared with ABC or AAC, in spite of the advantaged circumstance, the piston has shinny spots around the ring at higher position?
Probably, a former user must be failed in the initial break-in stage and a miserable YS 60 FS motor has been thrown away because of poor performance.
Crank shaft supporting main bearing has uneven ball wear not because of ordinary use but because of operating in the critical condition.
Now, I made up my mind to save this motor and to survive acquiring the original performance as designed by Mr. Yamada.
Removing concave surfaces on the piston wall caused by over-heating handling would be carefully reshaped avoiding unnecessary slipping resistor, piled carbon and sludge would be removed and the main bearing # 6903 would be replaced.
Following the Physical principle these kind of task is not always difficult.
Hoping this weeping and beaten-up motor would fly into the blue sky like a Phoenix in very near future.

Modification has accomplished on OS 40 LA forming the Schnierle main port successfully. The procedures were done on both cylinder sleeve wall and forming gas way inside the case. Keen concentration and special tools such as Carbide cutter were required to carry it out.
Because this modification is experienced on OS 25 LA motor last year, the task on 40 LA was not so difficult one but not so easy.
Later investigation about 40 LA models proved that the end stage production model has main Schnierle port, that has one piece rear cover plate with the needle valve body, not an independent metallic holding stay.
As I have formed the main port with oblique angled gas way to grow plug direction, manufacturer's design of it is horizontal parallel to the piston top surface.
I'm looking forward to compare my modification with originally 3 ported 40 LA model.

Very slight stuck feeling just before stopping obliged me to investigate the reason, right rear wheel was the criminal. Though a rear wheel nut loosening procedure required some muscle work, I did it without hesitation.
Finding out some break fluid leak there at leading side sliding pusher portion, cleaning was done on the cylinder inner wall and pushing part on both sides.
Any anxiety in break system spoils a fun to drive my VW Super Beetle, so the rubber repair kit was ordered to FLAT 4 VW shop in Tokyo before long. Ordered part might be expensive, small and tiny rounded rubber sealing and covering boots cost as much as 1,000 yen?
Anyway, fully overhauling including fluid replacement would be done while the holidays, the end of this year and a new year vocation.

Is it worse to escape or to run away from something?
Is it better to fight or to confront to anything definitely?
Is there any fear to be isolated or to be a village odori?
An inquiry by some 13 years old girl, " Why is it wrong to escape, any beasts go away from things unpleasant or dangerous?" moved me so much.
The cultural society has a tendency not to recommend evasion, for example, a soldier who escaped from strategy front is easily killed with rifle shooting done not by the enemy but by friendly force.
Are we obliged to obey blindly the unexplainable manners and customs in peaceful days here now? Of course I know that, in order to keep some group in peaceful condition, there must be any decisions to be followed, person who cannot accept the Law would be isolated or be bounced off. We often stand on the point to choose, stay or escape. A safest way of living in a group is obeying and following the Law, thinking, saying and behaving the same as others.
A person who do not accept decided manners and customs should leave the group.
Incidents and conflicts happen in a Family Society in the World. Probably, he or she would see another comfortable world outside after that.
So, we don't have any reason to deny to run away, to leave or to escape however difficult to do that in a settlement society.

Now we got into winter season in Japan and the temperature outside became lower than zero centigrade.
Following the circumstantial change, the physical property of materials changes also especially the viscosity of oils in a car. As the brake fluid is not made from mineral one but from vegetable one, deterioration and degeneration of liquid material sometime causes clogging in a mechanical constructions, among them operative brake cylinder inside is not be ignored at all.
My VW Super Beetle has drum designed brake systems on 4 wheels, 5 years interval from the latest maintenance needs periodical checking if the systems keep working, a possibility of one hand operation would be doubted, leading side or trailing side.
I'm going to proceed to a muscle working on the break system maintenance today, but it's relatively convenient for me to do that because the temperature is low and I need some athletic training these days.

Wondering in the Web site this morning, I happened to come across an interesting lecture about Emotional Condition, the comparison between the ancient nomad people lasted for 10,000,000 years till the agricultural race appeared and the settlement ethnicity, lasting for 10,000 years. The influence in people's mind caused by the Settlement Restraint is very impressive and moved me so much and I would like to dig this title a bit more.
