| + | * The breather valve is not a PCV valve but rather a regular 91-03 umbrella valve, [[techtalk:evo:engmech07#buell_xb_type_breather_valve|Click Here]] for more details on the valve. | ||
| + | * The breathers reside higher up on the boxes and should run a little cooler than the OEM Sportster umbrella system (may last longer). | ||
| + | * You know longer have to deal with the hoses coming off the heads as an upgrade to your breather venting system. | ||
| + | * You have to run vent hoses either to the air cleaner or somewhere else. Do not put a filter on the end of the hose. | ||
| + | * Most importantly, this upgrade WILL NOT STOP the occasional drips and condensation out the vent hose as that is an inherent symptom of the machine. | ||
