Buyer beware, my EFM clutch died after 20 miles of riding,went back to dealer who installed we called guy who sells these he was rude and got mad when we asked for our 1000.00 back, not including machine work. He said people arent shifting it right ,dealer prolley didnt install right, so im out 2k with installation and machine work, dealer is reinstalling my stock clutch back in...Ill just endure the pain before ill waste my money on these wonder products. My dealer had 2 other ones come back also, so dealer informed mr EFM they will no longer use his product...Like my dad said (rip) if its too good to be true it prolly is...
