Description

ISVINTAGE cylinder piston piston rings compatible for SUZUKI RV90 RV 90 90cc

Please pay attention to the exhaust port in the second picture, this may not be the same as your original car,

this is a modified exhaust port, this structure is more reasonable and sturdy.
You need to modify the exhaust pipe, you just need to weld a round iron pipe to the head of the exhaust pipe.

Note that the diameter of the interface between the cylinder and the engine in the picture is 57.9mm. The size of your RV90 may be 56mm. Because this is to change from 90cc to 100cc, you need to slightly increase this position of the engine Or use a lathe to reduce the cylinder liner diameter.

You will find that the modification is perfect.
The quality of the cylinder and piston and piston rings are all good.

Piston diameter: 50mm Piston
pin diameter: 14mm
