Cheap, much can power up than normal, then you there is also a sense of security because the Kitako, whether very good! But people anxious because only there was a little burr of whether it is better to the deburring (but was a good level even without)

Product is of satisfactory, but it is hard to understand in this site to find a fit of parts. I was ordered to find the vehicle identification number, but now end up buying only the piston does not fit the shape of the piston.

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

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.

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.
