what would happen if i put a stage 1 exhaust cam from Hot Cams? it has auto decompression on it... would it be the same as in putting 03 yzf450 exhuast cam like the normal mod? or do i have to put both intake and exhaust cams for it to work. what would happen if i put both cams would i get less compression like the regular mod??? or would it build more by holding intake and exhaust valves open longer?
