well ive had the pulley kit on for sometime now and i must say i am very happy with my purchase. gains are very respectable for what your paying, also helps to complement my other bolt ons.
Install was a breeze until the crank pulley.She was a ****. i tried 3 impact guns, then torched it twice. the torch was the key, it came right off. So install took prob 30min for everything but the crank pulley. crank pulley added a good 2hrs to my install.(cant blame this on nst)
I recommend getting this before you get an exhaust on your r18a1. and if you do purchase this, think ahead about the crank pulley.
