*Kart tank save a couple pounds over OEM
*If you are running MSD TL you can save anouther 10 by running a lead acid motorcycle battery.....4lbs, that will last you about an hour of riding time,
*Carbon fiber ride plate can shed anouther 3-4lbs off the rear of the boat. Weigh an aluminum plate sometime.........its rediculous
*I milled part of a RIVA manifold out to recess the reed cages and lost anouther 2.3lbs.........now the entire manifold and reed cage assembly weighs less than a RIVA manifold alone.
*Replace the factory waterbox! Running a X-metal box will save you almost 10lbs
* Lose all the OEM rail guards, front bumper guard, tray pads ect and just turf it. I bet you save 6lbs just in getting rid of that garbage.
*Take a grinder and remove the overhang that usually is visible along the bond line of the SJ. That may save a few ounces. Also clearence the rear of the tray for a trim system or cut it off the rear lip. This will not only save a little more weight but prevent the rear of the ski from catching water when the nose shoots up.
*You can also just reinforce the top deck of the ski and not continue onto the bottom deck. That will save a few pounds and if you are a flatwater rider it is doubtful that you need all that extra reinforcement on the bottom. The bottom deck is typically 2-3 thicker anyway.
** Be picky in what parts you buy. A b-pipe weighs less then say a Protec pipe. A RRP weighs more than a Waterdawg pole or X-metal pole. If your goal is to save weight don't make decisions that add weight........but its all in what you value. If you want a tank of a hull, reinforce the crap out of it, but lbs add up quick. If you want pole adjustablity, get a RRP. It will cost you a few pounds but it is all a matter of what you want.
