On my 1997 Ultra Classic, Last week I got it back from doing a stage 3 upgrade on my 80'' EVO motor. Remember this bike came factory with 46HP. The red lines are the before and the Blue lines are the after. I am happy with the 12.25 HP gain. And 76HP on a EVO is enough for me. Plus I had NO idea before I did the stage 3 that the bike was running this lean. Look at the upper red torque line how it was falling off. But with the upper blue line you can see the diffrence when we put larger injectors in it how it richened it up with decking the heads .030 and polishing them. kept the smaller valves to increase low end torque instead of high end HP! Really it's a bagger not a 1200 Sportster!
