Okay so I'm a DRR guy, but picked up these Polaris 90's for the kids to ride at the house. One of them has that awful automatic choke on it that I want to do away with. Rather than buying the manual choke conversion, I wanted to swap one of my 21mm OKO carbs on it with a matching intake, but is that an option? These things came with tiny carbs on them, maybe 16mm? I tried one of my 21's on there just for kicks and it won't start. Wondering if there is something I don't know or reasoning for the smaller carb aside from just building these for optimal bottom-end from the factory.
