    Charging system troubleshooting

    Too bad that a Flywheel needs to be installed and the Engine completely assembled, started and revved to test the Flywheel Magnet and Coil Voltage Output to find a sketchy Flywheel. So if the AC Voltage Output is low, still don't know if the Coil or the Flywheel Magnets are bad or both. Then...

    62t zeeltronic installation

    The 2 Red Wires supply Power to the Starter Relay and to the Zeeltronic CDI. There is one extra Red Wire required because now, the DC Zeel CDI needs DC Power directly from the Battery whereas the Stock AC CDI got AC Power from the Magneto Generator Charging Coil (Brown/White Wire from Flywheel...

    Hi Comp JS440 w/ Copper Head Gasket, do I need O-Rings?

    The Annealing Temperature varies among Metals, but the Annealing Process is similar. Most Metals harden, just like Copper does but at different stress levels, when deformed or cold-worked. "A similar process can be followed to anneal steel, brass, and aluminum, but the difference lies in their...

    Hi Comp JS440 w/ Copper Head Gasket, do I need O-Rings?

    Won't rapid cooling harden the Copper Gasket? Thought it needed to be slowly air-cooled so that it becomes Ductile (softer) for a better seal? That's what Annealing is supposed to be: heat then slow cooling... If making a knife blade, a rapid quench/cooling would be needed to make the Steel...

    DASA 1200 burning up orings

    What type of Elastomer are the O-Rings? Are they Viton or Harbor Freight Rubber? Viton has the higher temperature rating of 390 F versus lower Nitrile and Buna-N... And what is the Squish on that Cylinder/Dome setup?

    Charging system troubleshooting

    No way to Bench Test a Flywheel (OCD hasn't built one yet ;)). The machining process to lighten the Flywheel can damage the Magnets by applying Heat and Bending stresses. So can using an Impact Wrench to remove the Flywheel Bolt, beating on a Flywheel trying to pull it out or the impact shock...

    89 X2 with a 750 small pin, Sudco blue 42mm Help?

    Should pop clean. No bubbling or fizzing. Means the Needle Valve is leaking. Maybe it's the Valve Body O-Ring. Or maybe its the Needle Tip with a wear groove.

    Can use Plumber's Plugs aka Expansion Plugs to block any Round Holes; two for the Intake Manifold and one for the Exhaust Manifold. Test thru the Pulse Line.

    Other 61X Powered Mini Jet Boat

    What Exhaust System are you running? The MSD Enhancer would require some fine tuning (Carb Adjustment Screws) versus the Stock CDI. The MSD Enhancer has more Timing Advance which requires a little more Fuel at the Low Adjustment Screw. And if the Engine is revving higher due to an A/M Tuned...
