Usually on an enricher,,,, Harley has marked the black Knob CHOKE.... Don't know why..
If your bike REQUIRES 7 minutes of ENRICHER to smooth out.. It is too Lean OR has a intake leak OR something NOT Right...
I would ask you to think this for a minute....
Your bike IS air cooled and IF allowed to IDLE for 7 minutes, there are Parts that WILL Over Heat even though the valve covers are NOT hot to the touch.. IT is NOT designed to be left IDLE that long... Just the area around the exhaust ports (valves) will Over Heat BEFORE 7 minutes is up...
Pistons and rings WILL over time fail Early from the over-heating...
And Smitty Is SPOT-ON and I would Take HIS statements as GOLD...
The Owners Guide book that comes with your bike Stated how to use the Enricher, and it does Say the proper way (Maximum) to use it.
I have always started MY sport and dyna when Cold by Pulling the enricher out and putting it back slowly, using the STAR drag to keep idle up THEN I'm off riding it NEVER more than 2 minutes in total time.. I take it easy and no quick twist of the throttle UNTIL the bike TELLS me it is ready..
YES all of MY Harleys have TALKED to me.. And because of MY care to them, NEVER a Edited word was ever used..(word Edited was MY Edit)...
