I have a Xpedition 425 with a 2" snorkle. The bike has ran rich every since installing the snorkle(it was jetted perfectly stock). I have also installed a HP kit from Highlifter. It has a great deal more power now but it still rich(146 main,3rd notch per Dynojet instructions).

My question is this.....
Should I go DOWN in jet size or should I consider adding ANOTHER snorkle to increase airflow? If another snorkle is added should I go with 2" pipe again or drop down to two 1 1/2" pipes?

I was prepared to jet down until I read gregsims post aboput SP500 performance. Any help would be appreciated.
