Question about 2007 Daelim Daystar
Yes All motorcycle chains currently being manufactured use Buna-N (Nitrile) rubber for their o-rings and x-rings and all these manufacturers recommend kerosene as a cleaner. Here's the formulation of WD-40: 80% Stoddard Solvent (that is similar to kerosene) 20% light lubricating oil and a bit of fragrance. Here's the compatibility of Stoddard Solvent with rubbers and plastics: Good Compatibility (OK for both static and dynamic seals) Buna-N (Nitrile) Chemraz Epichlorohydrin Fluorocarbon Fluorosilicone Kalrez Nitrile, hydrogenated Polyacrylate Teflon, virgin Mixed Compatibility (OK for static seals, but not for dynamic seals) Neoprene Vamac Fair Compatibility (OK for some static seals) Polysulfide Polyurethane, millable Poor Compatibility Butyl Ethylene-Propylene Hypalon Natural rubber Silicone Styrene Butadiene Consequently, WD-40 is safe and effective as a chain cleaner and corrosion inhibitor. Link: http://www.efunda.com/designstandard...dard%20Solvent If you clean with a soft brush and WD-40, and plan to follow-up with a chain lube, you can reduce chain lube sling-off if you first remove the oil residue that WD-40 leaves. This residue seems to prevent some chain lube formulations from sticking well to the chain.,,,
