I just recently rebuilt my 04 flstci did bottom en and top end 95 " installed the new breather designs everything was good for about 1400 mile then on road trip 100 mile from home i blew out oil cap limped bike home .
I found i was building up pressure in oil tank makes no sense engine is new right.
Well removed the new breathers and found a design flaw where harley glued on the gaskets to the breather the glue oozed out and caused the diaphram to stick causing the pressure concern so i got new gaskets for my old design and reinstalled them and fixed the concern
Has anyone else had this concern with the new breathers
I've seen a few new breathers in my builds and never saw an amount of glue to do any damage....very odd.
I wouldnt have thought so either but i got the proof sitting on my bench at home and i did not apply anything to them when i installed them.
it was definitely the adhesive that harley used to stick gaskets to the breather
