 +====== Symptoms of Breather problems ====== 
 +Read more here on the [[techtalk:​ref:​engmech04#​engine_breathing|Engine Breathing System]] in the REF section of the Sportsterpedia. \\ 
 +The most noticeable signs of breather valve problems are weeping gaskets or oil excessively leaking out the breather or puking oil out of it. \\ 
 +When the umbrella(s) gets hard, it doesn'​t flex well to allow the engine to breath out on exhale. \\ 
 +Then the trapped in air is compounded on the next stroke. ​ The excess air contributes to more vacuum created and implodes the gaskets. \\ 
 +Or it contributes to too high of oil density and slings excess oil out. \\ 
 +Other factors are involved so results will vary. \\
