Rob Posted February 12, 2012 Share Posted February 12, 2012 Alot of the older R's had aircleaners with the extra warm air tube,but they still only had one element,most in fact were oil bath.The tip turbine air cleaners had 2 separate filter elements in the canister.Yes, mine is oil bath.

57 bcr Posted February 20, 2012 Share Posted February 20, 2012 I had a '79 R612ST (Canadian)300+ 315 hp,RT-12509 9 speed Fuller, that had the 2 tubes and the hood scoop! The air cleaner housing was actually stepped down at the top.It had an air controlled butterfly to get air from under the hood (like the old oil baths) during rain or snow.The scoop had an element under the hood that filtered air for the tip-turbine.I changed it to a 2 stage (USA style).Much less plumbing to deal with,both filters were then in the same place.
