Cylinder with piston YAMAHA JOG90 50mm TW

YAMAHA JOG90 cylinder with piston, 50 mm bore. The box holds the cylinder, the piston, the pin, two rings and two gaskets.

• The set shows: a black finned cylinder, the piston, the gudgeon pin, two rings, a metal head gasket and a paper base one
• The body has cooling fins and no hose spigot — it is air-cooled
• On the maker's drawing the cylinder bore is marked 50 mm — the same figure as in the name; from above, another 50 mm between the stud holes, and from the side the inlet flange at 20 mm, 25 mm and 47 mm
• The gudgeon pin bore is 12 mm
• The same category also holds a YAMAHA JOG 80 with 47 mm and a JOG 60 cm³ with a 44 mm bore — the same line, only narrower
• Wear can be seen with the naked eye: lengthwise scratches on the cylinder wall, a polished piston skirt, a ring that rocks freely in its groove — then the whole group is replaced at once

To be straight with you: which exact models and which years this cylinder is for, the maker did not state, and we do not guess — write us your machine or send a photo of the old part. Before ordering, take out the spark plug and measure the bore of your old cylinder with a caliper, along with the thickness of the pin and the stud spacing — we will check it before you order.
