I had a used EFM in my '01 XC300 for a season or two. It had bounced from owner to owner and I traded it for my stock clutch parts. Turns out it had a design/manufacturing flaw so I became very familiar with Garry, who was helpful. In the end we got it working but I went back to a stock clutch and would consider only a Recluse if I went this route again. But using the clutch is part of my riding style and I'll just stick with the old fashioned clutch for now.
