update! my moto blue lower crank pulley from rpm outlet is way off i had to use the lock washers to shim to get the lower pulley to aline with my other pulleys and still having problem. rpm outlet is known for its stalling tatics . im still waiting to hear from them ,, i missed my dyno date cause of this , which a lost my 100 depoist, i got to wait to get back on the list , which the dyno is 170 miles away from me btw. i shouldn't have to space it out. its a defect. iam sure there going to want to send me a new one , which btw isn't an easy task! i dont want moto blue one again. they dont want to refund you any money. in store credit only . i jumped from $225 credit i had to $299 with this pulley . there seeing more money from me every time i return something?
