Just about to add the oil pressure guage to my 07 FXDC.It has the california smog canister still mounted.After reading ALL the BLOGS about cooler,MY question is can a softtail cool be hung WITHOUT MODS (COOLER THAT IS)&nbsp\\;to the top of the frame rail?DO know the frame tube is larger then a soft tail (1 1/4 i think)&nbsp\\;Has any one done this as i&nbsp\\; want it vert above the canister.they state that it will run oil ABOUT 10 to 20 degr.cooler and you can see the rise in oil pressure.She has been dyno tuned so that lean problem went away(along with 10% of my fuel milage).HELP "Johnny B.
