Servicing of small Aftermarket Oil Breather Units Just a quickie, I fitted a small aftermarket crankcase oil breather filter unit.. junking all the underseat / rearend pipes etc... 1) because my underseat breather box cracked 2) because it neatens up the rear end of the bike... However I did notice that after about 1kmiles it you can see the black oil in / on the filter, do you need to service the filter, cleaning it every so often, or is this just normal and no further action is required? |
