On your first post you went over what was on your sled.... I didnt see anything about transfer rods???? They make a world of difference, if you dont have them get them... IMO anyways because they made a world of difference on my holeshots. Definately make sure that your powervalves are clean and adjusted properly. Go over everything every bearing that you can to make sure theres no drag anywhere. And maybe try running your track a little looser not to the point of ratcheting but as loose as you can get away with. I've seen my buddy's F7 get absolutely cleaned by an SRX and it has pipes and clutch work done to it, with studs so its definately a possibility i think that you will destroy him.
GOOD LUCK!!!!!
TAKE IT TO HIM AND SHOW HIM WHAT HIS ARCTIC SCRAP IS GOOD FOR!!!!!!!
