What exactly are you looking for in an aftermarket hull?

You will need sequential pilot jet sizes because they are sensitive and have no external means of adjustment. I have never needed more than four once I did some homework. You should not need more than 3 different sizes of mains, #12.5 apart because the top screw can cover the spread. Tune the...

You have to lap the cylinder deck and head for a good seal. The O-rings are for water not cylinder pressure. Its uber important that the surface of the domes are perfect, no scratches or dents. You will know if the dome is leaking by the pisser stream. If its broken then its leaking. O-ring...

Yes, fill the area in front of it RTV. Like I said the O-ring sucks by itself.

The ride plate and pole length have most to do with your height and weight as well as the way you ride most of the time. If you are 6 feet tall and 200+ then you will probably need a long plate and shorter pole. Little guys are fine with the stock pole/plate. You don't need a finned plate on a...

You are massively over propped, basically stuck in overdrive. Find a Solas "S" 14-17 or a concord 13-17. These are the lowest pitch Solas makes but are still a little too much without modification. The Skat 12-17 swirl is good. I have found that a 10-16 hooker is on the high side for a 701...

NO, there's not.

You did not mention your impeller, but unless it has been bent very flat boring the nozzle to at least 85mm will make a very noticeable increase in thrust. This is especially so with your mod chamber and the fact that nearly all props are too steep out of the box. Dont worry about the taper...

At one time they brought $200-$300 used, now I dont know. Not worth anything to me considering I just threw away a brand new nose piece.

My lightweight carbon chambers will sizzle water just like a metal one. They can be made very light if you are careful to make them round, no flat spots. All the advantages of composites are lost when the fiber is not in tension. The gas tank should be modified to clear a round stinger.

Condition is the most important factor in an old ski.

Im still wondering whats wrong with Standard SBNs. I have a Keihin 42 that clearly needs another pilot hole drilled in the body but never noticed this problem with an SBN. The aftermarket carb people are going to have to provide more information about their products. I think too many people are...

Size seems to sell and jetskiers only know how big their butterfly is. Aftermarket carb "modifiers" have wised up and given the consumer something to brag about while secretly leaving the correct size venturi in place. We need a four needle carb but that cannot be achieved with the SBN. How...

Any aluminum sheetmetal pipe will crack eventually, none are designed to last.

Thats a bad idea. You can get some benefit while going fast over chop but it hurts hookup at low speeds. No good reason to exceed 7500 unless you are a racer.

The front cylinder on a kawasaki 750-800 is usually the hot one, unlike the other brands. You simply found the limit of whatever fuel you were using. The jetting may have been too hot and/or the spark was too early. Compression at 190 is certainly a lot for pump gas if you do any full throttle...

You can also install a small tab to your rideplate to hold the grate in if the shoe ever broke.

Crankcase volume changes can affect carb tune but wont change the pipe tune. Have you lost peak rpm? Sometimes the top end feels a little flat after doing response enhancing mods like adding compression and reducing flywheel weight.

Loctite works well on fasteners that never need re-torquing. Anti-seize doesn't seal water out but acts as an anode between steel and aluminum. It works but is like treating a patient after you have made him sick. BTW it must be zinc not copper anti-seize. My personal favorite is teflon thread...

Port the cylinder instead.
