C70 boa up
5
From Japan

C70 engine burned down. Although I did not write C 70 in conformity, I thought that it was probably because C 70 was written somewhere because it is a pure bore up of C 50, so I thought it would probably be ordered. The result was fine.

It is cheap, it can do much more power up than normal, there are also security feeling because it is Kitako and it is very good! However, since there was only a little Bali, people who care are better to take bali off (although they did not have to do)

Bore up of turnip engine

Although the product is satisfactory, it is hard to understand in this site to find the fit of the part. I ordered it from the body number and ordered it, but the shape of the piston did not match and I got to buy only the piston.

Press Cave Bore Up

I think that you can bare up if there are even tools for the first time because instructions are attached. Once I mistakenly bought the one for 6v so check it carefully and let's buy it.

4 cycle engine reform

This time it was the first time to do a 4 cycle engine boost, but without unexpected hardships, I was able to go to the explanation reasons and build an engine well, as the torque also rose and the slope would rise smoothly became.

Repair?

It is a monkey which we own for nearly 40 years. I bought it because I am out of power, I intended to replace parts. It is an amateur to change the engine. It is moving, it is very well, my talent is scary?

Super Cub 50 Bore Up

From Japan

It was the first bore up. The actual work was about 5 hours. I was able to work with service manual and maintenance book, attached manual. The oil leaks from the gasket unless it is assembled with the prescribed torque, so a torque wrench is required. Black and silver are the same price and kind. Other net shops were canceled, just because there was no inventory of stock for orders. Monotaro is saved because we know whether our stock is in stock.

I was wondering whether or not to bore up when I saw various writes or something, but I got the right answer! It was my first time to bore up the 4th stick, but it was OK without any problems. Not exaggerated but a different thing. I made 14 sprockets, but I ordered 15 dollars because I could not blow it out immediately. Recommended if you get lost due to lack of power!

Bored up of Little Cub

From Japan

Although it is a part of the metal gasket of the cylinder head, the O ring mounting part was different in shape from the genuine part. Since the groove for O ring attachment was not digged on the cylinder side, O ring could not be installed. There is an oil leak. Which items are such things? Is there not any inquiries from other buyers? After two days I will use it at work, so I am in trial and error to manage somehow.

As expected is KITAKO. There is also a sense of security since Honda's cylinder has been remodeled. The finish of the piston and the method of assembling the OK ring are also written. It is surprising to have written how to draw out the piston pin. As for incorporation, we just remove it and attach it, but I can not recommend it for those who do not know or those who do not have knowledge of torque wrench gasket. It is suitable for a boost of a horizontal engine for the first time with knowledge. Although there is no evolving ability when asking for mower power, it is very good that you do not have to touch the oil pump, cam, and cab with 75 cc. It was assembly to acquaintance's turnip, but working time is 2H. I do not have to prepare the packing and gasket, but it is helpful, but I have to match the T mark with the O mark. Although it is not necessary to do a task of confirming the matching if experiences top dead center, there is no gasket of the generator cover, so if you do not own it it would be better to ask the generator cover gasket as well I do not.
