Smoothspyder has a new belt tensioner for the RT/RTS/RT ltd. This tensioner will also fit the 2009-SE5 spyder. Everything you need including the ruler is supplied. Follow the direction and the belt track doesn't change. Be sure to check the clearance between ebrake pawl lever and mount. This unit is more sensitive to adjustment inputs than the under belt unit.
Thanks Jim for all your work on developing this unit.
