About compatibility between the piston
set, connecting rod set and crankshaft
(by model year)
Piston set:
As the component parts (piston and piston
ring) of the 2016 to 2020 models are different
from that of the 2015 model, the 2015 model
and 2016 to 2020 models are not compatible
each other.
Be sure to use a combination of a piston and
a piston ring of same model year.
Since the piston set of the kit consists of
pistons, piston rings and piston pins, the set
enables installing those items on any model-
year engine at once.
Connecting rod:
No change.
Crankshaft:
As a thrust bearing is added to the #4 cylinder
for the 2016 to 2020 model engine, the 2015
model and 2016 to2020 models are not
compatible each other.
The 2015 model crankshaft is currently not
available in the kit.
Please purchase a Yamaha genuine part
when a 2015 model crankshaft is needed.
