Does the intake snorkel have a rubber baffle reducer inside of it? If so, remove it and see what happens. Our sock Zuma 2 stroke airboxes have one and once removed we can run pretty much any set up with no issues. Also, once you remove the rubber baffle inside the snorkel (if it has one) OR get a fancy looking pod filter you will have to WATCH YOUR PLUG! Better yet pick up a cheap plug seat temp gauge (Trail Tech makes a nice one) and find out what max temp range your kit (or stock motor set up) normally runs in and MONITOR it till you get it all dialed in. On the noise. I know I picked up a bit of noise on my 125cc 4 stroke build just from installing the bigger top end. That being said, make sure the cam chain tensioner is working properly. The Zuma 125 tensioner was very finicky going back together, and didnt hold good tension until re-installed a second time (seating issue with the spring).
