    No gas squirt when twisting throttle, does that mean bad accel pump?
    Would that cause the motor to not start also?
    Thanks!

    see if the pump is turned off (will look like a idle adjusting screw on other side of carb)or the diaphram is bad,not a big fix either way

    I don't think it's an adjustment because nothing was changed before it stopped starting. The accel pump is not adjusted off. I think it must be the diaphram that went bad. I will get a new one. Thanks guys.
    The bike should try to start even with a bad accel pump. There is gas in the bowl and it should be sucked up from the main jet. I think something else is bad like a leaky manifold gasket or weak spark. It didn't start even with gas sprayed into the carb or even with starter fluid.

    or stuck float not letting enough gas in.

    Pull the carb and go through it, still
    should shoot fuel into the carb if it has the pump

    D's didn't have a pump,

    E's N G's do...

    Make sure all the bits are in the right place.

    Crap happens check the screw anyway...

    How do I check for weak spark?
    Should I hotwire the ingition straight to the bat tree?

    three things

    Compression
    Fuel
    Fire

    Check compression, if both cyl have compression
    move to fuel,

    IF carb is getting fuel to cyl, then to spark

    or any of the three in any order, I just always
    check compression first as you have to pull the plugs
    to check spark anyway.

    Did you have spark before? Did you change anything to the
    ignition? Are all the grounds goodntight?

    I did all three and all is good but the spark looks weak. White and barely visable. I think that's why she doesnt start even with starter fluid. The compression is putting out the weak spark. I will check the ground connections.
    Can I hotwire the ignition module to bypass the ignition switch and breakers or is that a bad idea?

    Well, probably not a good idea...

    Turn on the power and check with a meter the
    power at each connection along that circuit
    see if you are getting 12 volts at the ignition
    if not, follow it back and find out
    what's sucking the power out of the battery on the way
    to the ignition...

    Check the wires if they are good,

    do you have access to a spare ignition/coil?

    Ok. No spares but I will check the voltage going to the coil and the coil ohms also.
    Thanks HRK!

    The bat-tree has been dying on me so I think there's a short somewhere.
    It should be fun to track it down. NOT!

    I replaced the diaphram and the o rings and now she is squirting again. It was too late to try and start her so I will try tonight.
    Does the diaphram get installed curve facing down like a umbrella?
    Thanks for your help!

    Weak spark was from a bad coil (cheap chinese junk only 5 months old). It checked out fine with the voltmeter but it wasn't working properly. Swapped it out and the bike fired up!
