    Buy the cheapest oil you can find since these bikes don't get any better with more expensive oils. The most preferred oil on here is Rotella. And the engine takes about 2 3/4 quarts.



    Don't over tighten the drain bolt because it is known to split the front cover.

    On this engine the engine case is shared with the transmission, thus the engine oil is also the transmission oil. DO NOT add any friction modifiers like Slick 50 or Moly to the engine oil, Energy Conserving oils are not recommended either. Best oil for the money is the diesel engine oils like Rotella.

    Engine and trans are unit construction so the trans lives in the engine oil.



    Unless you mean the rear axle, in which case you want hypoid gear oil, - SAE 80 below 41 farenheit or 90 above.
    Help with handlebar and ignition switches.

    I've been using,"Moly" based products in my cars and bikes for over 30 years and never had a problem with clutch slip.My present two CX have Molyslip in them and have no clutch slip.This is different from friction modifiers.

    I have put lucas in all the cars I have owned at one point in time. I believe on the bottle it says you can use lucas in a wet clutch system. It is a smaller amount i think 10 percent as instead of 20 percent. Then again this isn't from experience, just what I think I remember reading on the bottle.

    Well I called the Honda dealer last night. I won't be getting filters from them. Just the oil filter was more expensive than both air and oil from Bike Bandit (including shipping). Slighty cheeper deals could be found on ebay but BB was easier.
