i only ride around my families property because there are no trails close by so i dont really want to buy a newer bigger sled till im older and have more places to ride but i would like to have some more power im getting a little big for the little old 340 now so what could i do? would it be worth it to bore it out and pot high comp pistions? i have a K&N filter and jetted a little. what could i do for exguast? i have done some clutching but what else could i do?
