TZM+YBR, installation bore up kit and back step kit

It is back step kit made in TTS to attach.
It is back step, but a position is the same as most stock.
Why will I attach back step kit?
An engine gains shift pedals directly now, and it is because it is "a reverse shift".
It is necessary to attach a link rod to make an original shift.

I summoned Atsubon.It is him to do this work.

There is the work that bore improves an engine. The engine of this TZM is changed. Originally engines of 2 cycles 50cc. An engine of YBR125 is installed this.
