The 720 Stock Twin Carbs are mounted Sideways (Regulators aligned Forward and Aft) to prevent the dreaded "Left-Turn Syndrome". Don't know if an External Fuel Pump was installed; if so, the...

That's more likely a Lean Seizure due to low Fuel level, Fuel sloshing away from the Pickup, and Air drawn into the Pickup Tubes and sent to the Carbs.

What happened to the Oil Tank?

It should still fit.You could use it as an Auxiliary Fuel Tank. Connect it to the Main Fuel Tank.

Auxiliary Tank must have a Tank Vent. No Return Line....

Roger that, Thanks!

That 951 Engine with the Tiny-Tach was in an SXR 800 Hull; no Display Tacho.

I only trust PET Tachometers. The Tiny-Tach was mainly there to track engine-hours.

Have you called Watercraft Magic...

WFO, not trying to be funny, but when I don't remove the Reed Valves, I usually gently probe them with my finger, Petal by Petal to feel if they are there or split.

Would this "finger" inspection...

Yes, SBT Engines can/will have different size Bores on the same Engine...

562864562865All the High Performance 951 Engine Rave Valves I've seen run on Exhaust Pressure.

Watercraft Magic can give you the correct jetting for your set-up.

Good luck on the Full Bore...

Beware that Full Bore has very slow turn around times.

A Local Friend waited 3 months to get a Kaw 750 SXi Cylinder Bored & Honed...missed most of the Summer Riding Season.

jar, you are lucky. You got factual answers from some of the most knowledgeable Guys on the Forum.

Most New Members aren't so lucky.

Heed their advice.

Will a Rectifier between the Stator and the Bilge make it work?

I know, more components, more things that can go wrong.

Simplest solution is to tie into Battery and include an inline Fuse.

Each Cylinder has about 450cc displacement. This would be similar to a 2-Cylinder Yamaha GP800R which has Dual 44mm Carbs (400cc Cylinder with one 44mm Carb).

The 800R stock jetting is #90 Pilot...

On the one hand, a smaller pin is lighter and allows the Piston to accelerate faster which is a plus.

But the whole reason Kawasaki went from a Small Pin (20 mm) to a Big Pin (22 mm) was to...

If your Carbs were leaking just by being on an incline that would show that the Pump Check Valves are not holding. Inspect and replace the Check Valves.

I keep looking for Wiley Coyote and the Roadrunner in those landscape photos...

Sometimes (don't know in this case) the threads are BSP: British Standard Pipe thread.

Why they don't consistently use NPT or Metric, I don't know.

I've seen both NPT and BSP being used in the...

Are you sure? Did you measure both SBT Bores to confirm?

They've been known to only replace one Sleeve, if the other Sleeve is still usable!

SBT removes the Nikasil and inserts Cast Iron Sleeves...

Tim,

The 951 SXR MSD Total Loss System has one dedicated Ignition Coil per Piston. So only one Coil fires its respective Cylinder only when its Piston is at TDC. It is NOT a Wasted Spark System;...

Power Valves need to be trimmed according to the Piston size. For each Piston size increase, the Power Valves Blades need to be trimmed. Or else the Blade will impact the Piston Tops.

You can use the Factory Pipe Jetting Specs, as these have more to do with the loss of Vacuum Strength Signal due to going to less restrictive Flame Arresters, then they do with the Pipe itself:

Try tuning it this way first, before lowering the pop-off pressure:

You can set the Low Speed Adjustment on the Submerged Trailer to the highest idle rpms, then open the Low Speed Screw 1/4 turn...

OEM is best, but I think SBT actually sells WSM Gaskets which are acceptable. Dress them with sealant.
