The man said their customer service was great....I've had one for almost 2 riding seasons. I havent had much luck, but i think the initial install was poorly done. It is at a different dealership now being reworked. EFM does stand behind their product...better than anyone else I've ever seen encountered.
1) Take it to a dealership that has installed these type of clutches before....its not for rookies..although the best miles between problems is when i worked on it myself. It needs to be true and level and everything needs to measure up very well. If EFM can install it for you, thats the best bet!
2)I had to remove the throw-out shaft and bearing completely, it kept getting hung up on the EFM Auto plate and would not allow the clutch to dis-engage. I now have a clutch handle just hanging from the bar...when i can prove better reliability..again, i think its more of an installers problem, then i will remove it alltogether.
Personally i am about ready to sell the bike, buy a ctx 700 honda, practice one footed stops for a couple years, then this better dealership has experience in linking the brakes, and moving the clutch handle to the right bar!
