How much Sea Foam should I use in my 2005 Harley Davidson sportster 1200 crank case and how long or how many miles should I run it in order to clean contaminants out of my bike? [SOLVED]

Thanks for the question! Add 1 oz of Sea Foam per quart of oil in the crankcase. Best practice is to run it at least 100 miles before you change your oil (just ride normally until you reach 100 miles – you don’t need to ride it 100 miles right away).
