Well, I’ve done just that and I did not like an annoying vibration buzz at idle, on the 1250 . My well tuned, 2014WGSA was a delight to re climb aboard . The increased feel of power on the 1250 could very easily be a throttle response trick ( dare say that ?) Yeah, I’m sure it’s been dyno’d . So, I’m not a convert .If you are buying one I would suggest you never take the 1250 HP GS for a spin.
