Ahh... motorcycle farkles are like crack. The first hit is good, leaves you wanting for more, and ultimately wrecks your life.
So that we could get gifts to our mothers on time, my wife signed us up for a free trial of Amazon Prime -- free two day shipping on everything. Between that and this thread, I spend $28 on a rad cap that I didn't have to have postponing yet again the $400 gas tank and the $1000 DS wheels.
Speaking of the gas tank, the more I think about it, the more I like the 1 gallon red plastic tank for under $8. Maybe I'll splurge and buy the 2 gallon tank for $15.
