I guess I should clarify my use of WD40. After riding and cleaning my chain when I get back and the bike is going to sit,that is when I spray the chain down with WD40. WD stands for water displacement. WD 40 does not lube a chain for riding,and will actually evaporate off of the o rings and chain,especially once it gets warm. I no longer run o ring chains on the klrs.But when I did,I use the white Lithium or PJs. The thing with PJs is you have to get your chain warm,then apply,then let it sit and "cure". Either way,PJs is messy.I now use the old style chain and keep it oiled heavily.Less drag and seems like quicker response. If your trying to keep a nice clean klr,this is not the way to go
