Okay, first of all get some hours on the machine before this weekend and then change the oil before you do, b/c you will be riding up high in the revs for atleast one run that way you can break the engine in some. Secondly, if it is stock, what I used to do to try to keep the front end down is ratchet strap the front down and compress the shocks, so there is more weight towards the front so you are less likely to pop it up during take off and shifts. Thirdly, depending on what the drag is on...dirt/clay....if you take out some air of the rear tires, down to 2-3 pounds it will allow it for more traction. Other than that, I would practice some launches, starting in first and second, see what one you like and what is faster. On this machine, if it is stock gearing, first should do. Also, use 93 octance, or higher, that would help a tad, be sure the air cleaner is very clean for most air flow, and then make sure the engine is at operating temp before you pull just like you would in your cars. Another thing to do is run it around and see where the shift points should be for every gear (i.e. where it still revs up a tad but not pulling anymore). You can opt to use your clutch for everyshift, or not, that is up to you. I personally usually do b/c I dont think I lose any time by using it, and I just keep it pinned pretty much the whole time. Also, use your body to help w/ the front end down, plant your heels in the guards and hang over the gas tank/bars as much as possible.
