Which Nibbi Carb

[BuffaloChinaRider]

Hey guys! So I want to buy a nibbi carb for my apollo deluxe and id like someone to point me in the right direction with which one to order! I was fine with the stock carb and my jetting BUT there are guys that have their brand new apollos going in the 70'smph when they swap to the nibbi and different jetting. My bike might be a bit rich because I have a 115 main in the carb, even with the after market exhaust that 115 might be making my bike too rich. My apollo gets in the early to mid 50's then starts not wanting to go anymore if I hit the throttle more. Almost like it lost power around that speed. I have a great ground for my ignition coil and I have ruked out any issues. I'm thinking its my carb/jetting I am going to go down to a 110 main jet and see if this helps my problem but my gosh I still have to order this nibbi ive been hearing so many great things about . Thanks!
