There is a separate solid state switch that is activated by the momentary button on tigersharks.

That is all that a direct injected twostroke is. They would be useable in a production standup, but there are more reasons why it wont be used and why no more production standups will be made. Remember that Kawasaki, Yamaha, and every other large corporation exist to make money and nothing else.

Bolt on a stock head and see what you have. Lower compression will soften throttle response so low pitched impellers/bored nozzles are necessary.

It will take someone with deep pockets to fund a large automated production run in order to cut prices substantially. The people who provide the equipment must also be in control of events and judging before a venture like this would be economical. Nobody will spend millions on production and...

That liner will attenuate the reflection which reduces the pipes efficiency. This may be a good thing on a 500cc dirtbike but watercraft need all the power they can get.

Now if we could get some more exhaust builders. As it is we are stuck with either 20Y/O 701 pipes or a Powerfactor. I like the PFP but want a longer version.

I talking about the very bottom, make the edge sharp. The rear bondline/tray will always be out of the water once the nose breaks over. If you intend to ride fast make sure the rear edge of the rideplate is the lowest part of the hull.

There are some good aftermarket gaskets but some arent so good.

Dont leave the rear edge round unless you want it to porpoise at high speed. It will ride like Danielle was on it.

It is too much for most applications. They were successful in closed course racing though.

Tro old 10-18 is a little more than a hooker 10-16.

A big hub impeller gets nearly half of the total gain if you want to take baby steps.

Without a doubt, the quest for more always ends there. Someone will read this thread and install a smaller main jet without realizing hes now 20 seconds away from a stuck piston. Just like posting the virtues of 200 psi and 30 degrees on pump gas, someone will try it with an enhancer and toast...

The odd rich guy or racer is about the only buyers for factory boats since kids cant get financing anymore. I can justify $6000 for a new SJ, any more and A/M is more economical. But I already have enough parts to finish one, without that Im sure a factory boat would be worth more to me.

The only bad part of using very large pilots is when you are forced to cover distances at low speed like crossing the rough part of a lake to find big boat wakes. The fuel burn is much higher than it needs to be. Bigger carbs increased my fuel burn by 20% on the average long ride because they...

There is more to it than blindly picking numbers. Reverse jetting is a phenomena that occurs with with SBN44,46, and some A/M carbs when installed on big engines. Freestyle throttle blippers need part throttle to be rich enough for good response, this means larger pilot. Larger engines...

Did that mild setup top 50MPH?

Solas could reduce weight and increase durability by simply boring the center to accept 6305 bearings. I think an inexpensive/commonly available 155-160 would expand their use greatly. Hull mfgs would likely make 155 inlets standard, as they should have always been. Everything in this sport...

I think you have to buy one in order to find out.

That is why I find "like new" used tigershark 640 stators for around $30. They work on 92-2003 750s
