Agree 100% that a gasket is required at the carb's base. This would be causing an air leak and causing the back fire.

That is the exact flame arrestor I used on my '96 GSX 800. I also had an R&D Recreation head(rec head) with 175 lbs. compression. I removed the OEM 70 Pilot jet and installed a 75 Pilot jet with no carb adjustments. I worked with Chris Marrone of WaterCraft Magic when I did these mods. Had good...

Can you post a photo of the R&D Power Plenum?

Looking at the carb specs for OEM carbs on your model. It shows the Low Speed screws opened to 1 full turn out; Highs - MAG(front carb) opened to 0(zero turns out) & PTO - 1/2 turn out So to be safe...always tune your carbs to be on the rich side to avoid engine damage and then tune from there...

The '97 GSX has the 782cc engine with 110hp in stock form. I ran my '96 GSX with a stock engine and an R&D Plenum and rejected carbs. You'll only need to rejet(change) the Pilot jet from a 70(stock) to a 75 size. I don't recall the carb screw adjustments though. I'm thinking whatever stock...

The 2 black ones with the handle bar pad attachments/covers are made by GT Manufacturing. Coastal & Thumb Saver brands are similar to the GT models(knock offs). I came across the Coastal finger throttle and bought it years ago and I love that thing! Was anodized in clear. So it looks like...

Are the carb kits genuine Mikuni kits? Genuine Mikuni Needle/Seats? You made no mention about the N/S. So that is why I ask.

I concur with the advice of this crew...only use genuine Mikuni parts. I bought aftermarket kits just to try them out to "test" this testament by so many others. But knowing the HIGH possibility of them failing. I had hoped they would work. But they proved me right. Just like all the other...

My advice is to download the factory service manual and read up on the jet pump section to get all the smut on the jet pump specs to get a long lasting rebuild.

Nice vintage part from back in the day! GLWS!

My thought upon reading your symptom was to replace the MPEM. Jess or Nick at Westside Powersports.com can rebuild or exchange your MPEM. https://www.westsidepowersports.com

OSDparts.com is the place to go! I buy 98% of my Sea Doo parts from them. They are very helpful and even have the special Sea Doo rental tools available for the big engine jobs, if you need them. The needle has a rubber coating called Viton. It helps to seal the valve against fuel leaks for...

I'm really bummed that this build will not be finished. It was a lot to take on going in though. So kudos to you and your energy, knowledge & unwavering dedication to the sport and to all the businesses you supported along this crazy journey! Maybe someone will buy it and finish it up(hint to...

The 787 motor is the engine that has the small Ground wire coming from the rear electrical box. The 718 motor does not have this second small ground wire. Nor does it have a rear electrical box. It has the grey electrical box mounted on the left side of the fuel tank. The main Ground is the...

I'll take the West Coast Exit/Steering nozzle combo, if it's still available...
