Crankcase Breather

Crankcase Breather

OEM Yamaha Part - Black

This is the part that sticks in the top of the flywheel cover that the breather pipe fits to

 Fits straight in with no modification

 Original part # 498-15371-00

 These parts were then superceded by 3YJ-15371-00 but this part has proved too big to fit in the crankcase hole, it needs trimming with a knife to fit. So we found these OEM replacements
