Wow! I love the simple belt idler clutch system. My only suggestion would be to replace that cheap bracket you have the spring attached to with something more solid. I've had brackets similar to that break and had to limp my bike home with zip ties and baling wire. Needless to say those brackets have all been/ are slated for getting replaced with 1/4" aluminum. Besta luck. Looks like you have a pretty sweet ride.
