    Little more speed out of GTX 260

    I picked up this '12 GTX 260iS Limited. 20 hrs on it.


    My buddy has a '13 RXT and my other buddy has a '14 SVHO cruiser. All 3 filled up with same fuel, we all weigh about the same. We ran them several times, the RXT had a leaking intercooler, he clamped off the water line for the day, so that's not fair but I walked him pretty good. The SVHO is what surprised me. I know I'm a good 130lbs or so heavier than the SVHO and fully expected to be left behind. That didn't happen. We never raced from a dig but 20mph, pin it and hold it runs, we are neck and neck. Decent water, not flat but generally calm. If my trim was 1 bar off center, the svho would just start to move ahead. 2 bars up on the trim and we where dead even and I might start to pull him on the initial hit. I was seeing 69 on the speedo.


    What can I do to get a couple more mph out of this GTX? I do see the ride plate could use some filling in on the bolt and edges.

    it did seem to hit 68mph on the speedo quickly and then took a bit for the 69 to show.
