Thread: Primary Chain Oiler

    Primary Chain Oiler

    Hi All,

    I'm trying to work out what I should set the oil rate on the primary chain oiler for my UL and WL.

    The manual doesn’t actually say and the advice I've received varies from "put a belt on it" to "just so it leaves an oil patch as big as the circle made when you touch your forefinger and thumb together"

    I'm the sort of guy that likes to be accurate (I measure with a ruler the flex on my chains to ensure they are spot on with the manual ) so I was hoping someone could give me a measure.

    Something like 1 drop every minute when the bike is idling or something like that.

    Thanks for your help

    I was always told by the old graybeards that there should be a spot of oil about the size of a 50-cent piece after parking overnight. I don't know how you can get any more scientific than that..! ;~)

    If your chain turns brown it's too dry. It's better to err on the wet side...

    Thanks guys, I've got the primary chain cover off and I was hoping to be able to start it and adjust the oiler while I was in there.

    Whatever you do DO NOT tighten the adjusting screw. That can break the seat and you will lose all oil control.

    Plan was to take it out, blow out the passage with compressed air as listed in the manual and then set it perfect.

    Looks like the setting part will be a guess.

    I'm not sure you could perform an adjustment by watching the oil mist dribble out the breather tube with the cover off. It's one of those adjustments that you do 'on the fly', so to speak. Start with it initially over-oiling (note Panacea's excellent comment) and gradually turn it down until you get that 50-cent-piece sized drop under the cover. Then periodically inspect the chain for a nice shiney wet condition. Just my 2-cents.

    Sounds like a plan Tom and thats just what I'll do. I get a little paranoid about these things :-)

    I still got a 1000cc 1980 Sportster on the road. To fill the primary chain cover up right one has to remove the tiny screw that's neer the botom on the side of the primary chain cover. Then the bike should be sitting up level as the primary chain oil gets poored into the primary chain cover untill some starts coming out of that small screw hole. That tlls you there is enough. It's just that the primary chain cover can start leaking. One can get the thicker gasket used on drag bikes and also try the Sportster Primary Chain Cover Gasket Seal.
