    Super Jet Superjet coupler too far?

    It looks the same as every other SN coupler coupler that I have ever seen. The shaft bottoms in the bearing so it cant go deeper than intended.

    Super Jet 701 exhaust on 650

    Super Jet Melted front (mag) piston - still trying to diagnose, help me out

    Make a piston stop around top center, mark both stops on either the flywheel or coupler, split the difference and call it zero degrees. Mark the case/flywheel or coupler 21 degrees early and check it with a timing light. Most aftermarket flywheels have more spark lead than stock. I saw a three...

    650/X-2 Rev limiter.

    There is no cheap way out but the limit usually is not in the way until the cylinder is ported with a good pipe and low pitched prop. A 1993-1995 650 ignition #3725 or 3726 will give you a 7000RPM limit with 5 degree retard. 750/800 electrics have even higher rev limits.

    650/X-2 92 JH750 swap into 91 650sx

    It is a simple swap and it will be a little better than the 650. Find a 750sx E-box and mount it flat above the battery.

    Super Jet Ported 760 vs ported 61x

    A more valid question may be "Why wont banks lend $10,000+ to an 18-25 male who will destroy the collateral in a year or two?" We will be back in business when that gets solved.

    Custom/Hybrid Pipe question

    It takes about $400 of carbon to get an 8mm thick chamber. What do you think they are selling? A composite pipe must be round with no flat spots in order to work well and save weight. A sheet metal dry pipe is by far the best power adder there is for the weight and price.

    FX-1 Fx1 Aftermarket Water box Info

    Use the stock box until it blows up, it will on the first good after fire. Then get a stock RN box. All aftermarket boxes are annoyingly loud and do nothing for power. A TDR will also eat two holes through your hull when the padding comes loose.
