NOT Sunjuku, "
Shinjuku", anyway, I do not know which parts you want,
but in Tokyo there is no stock of genuine Chaly(C) parts at any bike shop.
In a large motorcycle supplies store, only external products are kept
and it is not be expected to receive C used parts.
Used parts in C are usually sold online or in the owner's network.
Basically, it's almost impossible for you to see the owner of C while staying in Japan.
Even if the rainy season is over,
the owners will hardly be able to ride because it will only have a hot and humid summer.
However, there is many pretty big bookstores in Shinjuku,
so you should ask the clerk if there is a stock of "4mini(four mini)" magazines or mooks.
If you buy magazines, you can get some infoas there is a bike shop ad.
Also there is a large second-hand bookstore,
but it may be difficult to find 4 mini magazines bc location is pretty mid urban city.
In Shinjuku, there is also a tourist info center with a talented staff in Shinjuku,
but no info on motorcycle can be obtained.
You can search for bookstore info with Google without going there.
