Has anyone tried the latest design of the TM chain slider? My stock one is worn out, and I'm wondering if I should go with the TM. I heard the earlier versions were both hard to install (swingarm removal required) and very loud. But the web page says they've addressed both problems, making them quiet with new materials, and redesigning them to allow easy installation. Can anyone back this up? If so, how much have people paid, and where did they buy from? Thanks for any help!
