My 670HO just doesn't go as good as it should. I am trying to figure out what to do to make it pull harder. My current clutch set up is as follows: stock arms, stock 16.4 gram pins, 280 ramps, 230/320 (pink/purple) spring, stock 53/47 helix w/ 19 lbs of preload, Goodwin teflon buttons. This is very similar to a set up that I ran on a 97 mxz 670 but it pulled much harder on that sled. I am considering going to 18.5 gram weights from Fast but I don't understand why I should have to run that much weight with the above set up. Any help would be appreciated. I don't like getting beat by my old 97 MXZ670 that now belongs to a friend.
Thanks
