Can't speak for a v-max old or new. Can say a busa ain't got what it takes though. From a dead start for 1/8 mile, its all us. (mines stock, so was the busa) After that his powerband kicks in and we're toast. Thought it may have been the difference in rider ability, so we swapped. My rock still ate me off the line with him on it, but I sure liked that powerband. Never did see it top out tho, had to shut er down because of traffic. for a fact, from a dead stop for the first 1/8 its all us boys..
