I have been using the BG motorcycle chain lube for about a year now,I used other lubes but did not like the white paint look on the chain I also not a big fan of lithium lubes do not seem to penetrait as well. as I started to use the bg lube black gunk came out from the chain and sprokets now just some residual stuf from the sproket cover. I am a beliver in the BG pruducts, the only way to get this lube is some automotive part stores or auto shops, but worth it.
