*For injection vehicles only.It cannot be installed on carbureted vehicles. *Cannot be installed on other than stock cylinder head. *Simultaneous installation of FI CON (Injection Controller) 03-05-0019 must be installed at the same time. *If the FI CON is not installed at the same time, the performance of the big bore will not be demonstrated and engine trouble will be caused.
It is a big bore kit that can be easily assembled by yourself. This light big bore kit is popular for street driving, and you can feel different engine performance from stock.
■Details The S stage allows you to increase the displacement without changing the stock cylinder head and crankshaft.

I changed the spec. to SP Takekawa SSTage Bore Up Kit 88cc this time because the 72cc stalls on a little slope! It was almost the same work as when I changed to 72cc before, but the instruction manual was very easy to follow and I was able to work on it like a plastic model! I was not able to run the carburetor at full throttle during the break-in period, so I did not change the setting from 72cc, but it is very strong and feels good! I can't wait to run it at full throttle and get it set up!View Detail
I think that it can be assembled without problems if the assembly is carried out according to the instruction manual. Torque wrench is mandatory I also have something to help with Engine Stand. Torque feeling rises considerably. Change to FSprocket 14 → 16 T Carburetor, Exhaust System is in NORMAL state about 70 km. MJ is a good feeling about 80
Since my friend got a second-hand Engine with Y back and low back, it is installed in Base car It was obviously strange, so I got OH, the Piston Pin 's Clip was disconnected, Piston Pin jumped out, Cylinder had an unrecoverable Wound, so purchase Cylinder and Piston's Set It is said that the cooling effect is higher than HCylinder, but there is no clear effect Piston also makes it easy for Wound to enter the groove where Piston Pin's Clip fits, whether the material is not good With this, I felt that Piston Pin 's Clip is off the shelf My MONKEY is also a pretty old Piston in Mukawa, but there is not such a thing, as it is rumored, is there a difficulty with Materials recently Makekawa (^ ^ ;;View Detail
