Hi,
My only problem with changing over to TBS needles is finding them. No dealer stocks them and it takes a week to get them, so plan ahead. I called 7 dealers and was willing to drive 120 miles to just pick up a set. No! They are not stocked and I almost got in an argument with the closest dealer parts manager. He said he couldn't believe I wanted to modify anything on an America. I told him Triumph engineers had a great design, but it needed a little adjusting and the bike is anemic and constipated to Brit riders of any age. He said he'd order them but was sure it would void my warranty. My warranty's been dead for nearly a year.
