I think it is necessary for beginners.
I bought this for my first Bore up work on my SUPER CUB 50FI 3-speed AA01.
It was explained in a way that even a layman like me could understand it. The instructions are well illustrated, and the handling of peripheral parts, such as removal, is carefully explained, and the cautions are easy to understand.
If you are considering Bore upetc. Engine custom, you may want to buy this before procuring parts.
However, as a matter of course, all recommended parts are KITACO's products. Even so, I think I can reduce the loss because I know what tools I need in advance. In my case, I'm using FI vehicles, so I would have been happy if there were some notes and illustrations for FI vehicles.
However, I feel that the amount of information at this price is unbelievable.
Also, I think Reinforced Oil Pump and Reinforced Clutch will be replaced at the same time when you bore up. "Below the waist." The recommendation is to purchase the product at the same time.
