Is a monkey who owns nearly 40 years. Because the force is no longer, it was purchased with the intention of replacing parts. To add a hand to the engine is amateur. But, it is what moves, is very excellent condition, much is scary my talent ...?

Super Cub 50 bore up
From Japan
On 2015-07-08 23:56:06
It was the first bore up. The real work was about 5 hours. Service Manual and maintenance book, was able to work with the included instructions. Since the oil leakage from the gasket and not assembled in default of torque, the torque wrench is required. Black and silver is the kindness at the same price. For obtaining the other net shop, it has been canceled without just manufacturer. Since Monotarou's is found to the presence or absence of its own stock, it was saved.

Bore up of Ritorukabu
From Japan
On 2013-12-07 22:35:19
It is part of the metal gasket of the cylinder head, but, O-ring attachment points had different genuine and shape. Since the cylinder side is also not digging the groove for the O-ring mounting, O-ring could not be installed. There are oil leaks. Which product also does it like this thing? Will not Toka inquiry from another buyer? Since the use at work two days later, is in trial and error or not somehow.

It was incorporated into the turnip AA type of engine.

Truly is KITAKO. So are remodeled Honda's cylinder there is also a sense of security. Finish of the piston is also OK which is also visible wrote how to construct the ring. The is written to unplug the way how to construct of the piston pin is a surprise. I just put disconnect with respect to built-in, but can not be recommended for those who do not have knowledge of the person and the torque wrench gasket are not familiar. If there is knowledge we have been facing in the Boappu for the first time of a lateral engine. And development of seek Moapawa is I do not, but the good not touch the oil pump cam cab in 75cc is very good. It was assembled with the acquaintance of the turnip, but working time is 2H position. It is helpful to say without the need for preparation of the packing and gaskets, but it must be combined T mark and O mark. Experience the confirmation fit if brought the top dead center work also, but I do not need to be performed in, because it does not contain gasket generator cover, it is not itself be safe is better had asked also generator cover gasket It might.
