    Hey I have a 2013 Yamaha aerox it has a pm tuning 70cc kit on it with 17.5mm carb with a 80 jet in also has malosso clutch and air tek variator and a q tre powerpipe the problem is the bike won't run properly with the air box on it's just splitter and pulls away very slowly I tried taking the snorkel out the air box still no joy I then took the air box off but then left the rubber hose on that connects air box to carb and it still pulled away very slow but picked up speed and was running alot better! Any ideas what this could be please it's doing my head in aha thanks in advance
