    Charging system troubleshooting

    Here's another way to check Flywheel Magnets: "You can use a multimeter to measure the resistance between each pair of adjacent poles on the magnet. If there’s a significant difference between measurements, it might suggest that some magnets are weaker than others." So all Flywheel Magnet...

    '95 750SXI Coffman exhaust Carb Settings question...

    Seen where Pam Coffman wrote that the Rocket Pipe was NOT made for the 750 SXi. If there is no Waterbox, you will have a hard time trying to dial in the Carbs. 2 Strokes need some Exhaust Back Pressure. You didn't say if the Keihin Fuel Pump itself was rebuilt... The Jetting and Pop-Off you...

    Haven't seen Duckbills come off. Had them on a 62 mph 951 SXR race ski and stayed put. But only really work when Ski is in motion. Will drain a little Water when on the Trailer and Stand. So far so good on the Square Nose. But I'm only chasing Buoys. The Versiplugs drain more Water and the Ski...

    SN Superjet fix and improve build

    Superjet not starting after melting exhaust hose

    If the Exhaust Hose melted, the Pistons probably melted too... Do a Compression check and report back. You need to figure out why the Engine ran so hot in the first place.
