Description
Cold-starting air-cooled engines is easier and more reliable with a compression release that reduces kickback and strain on your starter system. The S&S Cycle 90-4915 gives you instant control over compression during startup—whether you choose electric convenience or manual operation—so you can focus on tuning and riding instead of wrestling with difficult starts.
