rzr 570 new clutch belt squeal

Need help, I just put a new SLP clutch kit on my 2015 RZR 570, I’m running 27" ITP’s, set up the new rooster weights as suggested, 1 red bolt with 1 thin and 1 thick washer lock tighted in, new helix and spring. Put everything back together and went for test ride it accelerated awesome but when I let off the accelerator and just before it comes to a stop there is a squealing noise that I am assuming is my belt. Any ideas?
