I've been running the 1500RPM torque spring in my 2006 Qingqi scooter. I noticed improved performance from the start. I have improvement in take off and hill climb. I recommend ZTR to anybody.

I purchased a ZTR chain tensioner for my 660 Yamaha Raptor. Then went on vacation through the desert where I road about 500 miles. To my surprise the tensioner showed no wear!!  James went out of his way to make sure my vacation was a success.  Thanks ZTR.
