As I stated earlier, I use BelRay Air Filter Oil for the flat, foam air filters on my two Zongshen motorcycles. However, I use No-Toil Evolution Air Filter Oil for the conical air filters on my two Honda motorcycles.

The No-Toil system is great, since I can clean the air filters in my kitchen sink, using soap and water. I can avoid using nasty solvents, and the dirty water can be poured down the drain. Once I finish up my bottle of BelRay Air Filter Oil, I think I am going to switch to No-Toil Evolution Air Filter Oil for all my motorcycles.
