Hey guys I got a 86 250es and Im looking for ways to get a little more power out of it. I put a set of 25x12.5x9 bear claws on the rear and she doesnt seem to like the weight of them. Just wondering if you guys had any advice on how to pump up the power. I was thinking maybe because its a older motor it might do it go to do a rebuild (higher compression pistion?)Im not looking so be a 200x or anything but a little more power to turn the bear claw would be great.
