I have an 05' with the Magura hyd. clutch. Before a recent ride, I back-bled the clutch and it felt good.....it went firm about 3/4" before hitting the handle bar. Then, after riding for while, the lever would provide no resistance, luckily the bike has a Rekluse so it was not a huge deal. After 30 minutes, the clutch lever would provide firm resistance, but about 1"-1.5" from the handle bars. Anouther 30 minutes, it would go soft again. It was very strange. So, in short the lever had various levels of firmness throughout the ride - from no resistance to great resistance. Any thoughts?
