Harley guys have been using this for decades, and it does indeed help most ride better. It's also addictive, and the costs add up quickly, both financially and mentally. Like with many drugs, close friends distance themselves, family becomes disillusioned, and eventually users transition into a completely different lifestyle. The excuses creep in, and reality doesn't matter. making money to feed the habit does.
Eventually things fall apart and "the lifestyle" comes to an end, sometimes ending life itself.
Be careful out there, friends, think before acting, think before speaking, and for Heaven's sake stay clean.
