I WAS getting 16-17, but then again my wasnt so hott when I bought it, burned oil, sputtered and the work (basically I'm rebuilding now after owning it for about a week!!) but I know some guys that get up aroung the high 20's low 30's with a stock setup, one size up tires (235/75 I wanna say, but cant remember for sure) and a weber carb. Plus they were all fairly "old" guys so they werent exactly leadfooting around town. hope I helped in some way.
