Oil question

[Alex28]

I've ordered a service manual for my 2004 Honda CRF230F, but in the meantime I would like to change my oil. I have a few questions, firt off how important is the specific torque that you torque the drain bolt? Can I just use a regular ratchet and make sure it's tight? And second of all does anyone know approximately how much oil to put in the machine? And I purchased Amsoil 10W-40 Synthetic motorcycle oil, is this a good oil? And I'm not sure what oil was in the machine previously, once I drain the old stuff is it okay to put this new oil in?

Thanks

Just make sure the drain bolt is tight and you'll be fine. Just make sure you don't strip it out! I wouldn't worry about your oil situation. Your bike will work just fine.

I have the same bike.The 230f uses 1.1 leters of 10w-40 oil. No senthetics and no special things in the oil.
