ITEM DESCRIPTION: NOS Yamaha RH Engine Crankcase # 126-15121-02-00.

IMPORTANT NOTE: On the Rotary Valve side...notice the hole for the countershaft: You will see two bosses which are blank. Some cases are drilled and tapped some are not (I put black marks to show the location). These holes (if your model supports) are used for an oil scoop to feed extra oil to the bushing. If your engine has this scoop... you can drill and tap the case or you can omit the scoop. The last picture shows this setup (this case is not the same part #... but it uses the same oil scoop setup) (picture is for reference only)

NOTE: We purchased the entire inventory of an old Yamaha dealer that closed down many years ago. This dealer was in business from the late 1960s until the early 1990s. We have 1000s of NOS and some used parts that will soon be listed . Please DO NOT ASK if I have this or that... the parts have not been inventoried so I have no idea what's out there? Check my store periodically (I will get them as soon as I'm able).
