Needing advice on jetting my 02 foreman 450. Im about to put an HMF utility series exaust on it. Does this model need the dinojet kit for this exaust or can i just go to the dealership and get the main jet and if so anyone know what is the size I need and what is the stock size. Im going to get a K&N air filter as well. The bike is snorkeled as well. any info would help thank you. Or is a carb adjustment even nessasary on this model? Will it hurt the engine if i run it with the exaust change and not the carb adjustment?
