Anyone else racing this race in Cuba New Mexico? It's a 32 mile track and amature quads are supposed to be doing 2 laps but I'm still hoping for 3. I just switched back to a stock head and was wondering if anyone else with a 686 set up simular to mine has gone this far on one tank (IMS 5 gal. tank) I dont want to pit for fuel but thinking I should put at least 1 gallon after the first lap to be safe. I havent got the chance to what sort of range I have with the new head, before with the ported head I was good for about 50 miles at race speeds before going to reserve.
