Well it didn't take long to tear the new to me 2011 Tri glide down after noticing it had adjustable pushrod tubes I had to take a look. It has S&S 551 gear drive cams in it! The previous owner bought the bike new which I confirmed but nobody knows when or where these cams were put in! The bike ran ok but figured I'd check it out. I sent the heads to Mega Flo for head work and Jim is looking at cams with 34* -37* intake close. There aren't many gear drive cams available for my application so I may have to go back to chain drive. What are you guys running for cams? TIA Ron
