I think that I will write the comment
Attached since it obtained this time.being related with
attachment -- Sprocket exchange etc. --
-- since the same day was used, it took round one day (with two persons).After the
Bore up was registered two sorts, and is run.When starting the
Engine for the first time, it was become tense, but when kicked several
times, it started splendidly.<(smile) br> which was impression when it has gone on a cruise in the
margin at 55 km/h -- although it tames, and it has not turned yet since it is inside --
-- a feeling of Power is still a different thing.Even Kami wants to turn early [
].

Since the price was cheap also in the bore up kit, this was decided on, but it is very much satisfied.
It is satisfactory at all in quality etc.
A description is seldom merely helpful.
since -- I regard a key etc. just as what is necessary being to purchase together.
Although he purchased together, he was able to buy it at a low price rather than he still bought other high bore up kits.
This quality is the highest at this price.

He got tired with a lack in 50-cc Power, and it purchased.
Even if there is no special tool, it can do somehow, but a torque wrench is indispensable.
Probably, the first person needs a service manual etc.
Attachment of a cylinder may be somewhat difficult for an attached description to the attachment of a piston pin which is not helpful, direction of a piston ring, and a piston.
Power went up clearly and the attached comment stopped stalling also on a slope.
A price is also cheap and it is recommended.

This kit was constructed by rebellious spirit by the thing that a friend does bore up.
Although he wanted that of SP Mukawa in fact, since the kit of SHIFTUP seems to have few people who have constructed, it was used as this kit.
Incidentally a description is not helpful.
Ape which a service manual and I begin -- custom -- the book to say was seen and constructed.
How about asking [ the person with uneasy doing by oneself ] a store? Since I wanted to do by myself as much as possible, I pumped up by myself.
Power went up the attached comment extremely.

50-cc slender Power could not be put up with, but bore up was carried out.
Because those who have stuck to the surroundings are not in the reason for having purchased this kit of the lot in inside.
Although it is an attached instruction manual, it does not stand on the role of honest.
If it is experience and those knowledgeable, it is satisfactory, but beginners' person will think that he is impossible, if there is no service manual.
Of course, Power goes up.
