engine, but it may be necessary to add the amount of oil depending on the motorcycle specifications.In the case of engine specifications
that bring higher rev limits such as ECU tuning, etc., we recommend that you refer to the following description.
（It is recommended to take the same action even when using the genuine oil pump.）
Additional oil amount.
・Up to 9,500 rpm : No need to add more oil.
・Over 10,000 rpm : Recommended to add the extra oil + 50cc.
・Over 11,000 rpm : Recommended to add the extra oil + 100cc.
◎ Product may have edges or protrusions. Be sure to wear working gloves.
(Please wear work gloves when working, even if a photo in this article show without work gloves.)

CO～ feature ～PY○ When the oil pressure is increased (by increasing the discharge amount than stock oil pump), oil may leak from the gap between theoil pump body and the cover plate (at high rpm), this makes it impossible to circulate the appropriate discharge amount.
To keep stable oil pressure at high rpm when discharge volume is increased, our oil pump has more number of bolts compare withsingle bolt(stock) to x 5 bolt, to prevent oil leaks. Also thicker cover to get more rigidity.
○ Our company's oil pump increases the discharge amount + 50% more (compared to the stock), and secures the oil pressure even low idling.
This oil pump also equipped the relief valve at the oil passage that opens and responds to the oil pressure change due to the engine rpm increase.
This suppresses an excessive increase in oil pressure, when engine speed rises at cold, suppresses damage to the drive gear, mechanismand sealing, prevents the discharge of more oil than necessary when the engine is running at high speed, suppresses the increase infriction loss, and stabilizes the oil level.
