My 360 chirps the belt sometimes when I take off. I have heard of using a red spring but I dont know what to get or where to get it at. So where have all of you gotten your springs and is the red one really the way to go?

 

Check the belt deflection, your belt might be a little loose, but mine does chirp a little at times as well.. 2 weeks ago I replaced the black secondary spring for the red secondary spring. I do like the red spring, but you will loose 2-3 mph on your top end, but your low & mid range is going to be ALLOT stonger, but with that your going to get more engine noise (running a higer rpm) I guess it depends on what kind of riding your going to be doing.. If it is all wide open easy roads, I'd say get the black spring, but if you like more mid & low end get the red. I 'm going to be using both. For the fall, winter, spring I'll use the red (mud, snow) & in the summer I'll use the black because I wont need the higher torque as much..
