| Personally I would stick with proper bike oil. Depending on what this guy is talking about if he means using say a 40 weight oil instead of a multi grade 10w40 then it can only result is faster engine wear as far as I can see. With a single grade oil it would be way to thick when cold and would probably not manage to get the oil circulating around the cylinder head properly.
If you are worried about the oil being made to use in a small air cooled engine (remember these are small motor bike engines not lawn mowers.....) then go to honda and buy what they recommend for a crf50.
Pretty much regardless of if the motor is water or air cooled it still has the same oil system so that should not affect it, only real difference is these pitbikes can get hotter then say a water cooled bike.
Hey pwnage5000 would you put lawn motor oil in a honda xr400 ? they are air cooled, how about an old GSX1100 ? they are oil cooled like most of the bigger pitbike engines......... |
