Here's a few photos from when I recently changed to steel oil pump gears.

Does anyone know if the '17 390 RR-S also has nylon oil pump gears? Are they just on all Beta 4t's?

Also can someone tell me what other maintenance I should be doing after 100 hrs besides oil and filters? The manual says to check or replace about half the engine and I'm not sure that all that is necessary. I'm pretty handy but i'm no gear monkey.

Thanks
