I have a very clean 02 700 144" with about 1700 miles on it. Now this thing runs really good but was kinda thinking I should do a top end kit on it before the snow sets in. What would you guys reccommend for pistons? I've used wisco in the past but just looking for maybe a little upgrade to. Now this sled is used for the wife to ride in the mts and for me to run around home which is 2400'. Not looking to big bore but a good drop in kit. The sled is 100% stock besides riser and boss seat.
