    Hi everyone,

    I purchased a 2004 Wee from an inmate about 6 months ago. The bike has over 90k miles on it.

    Here's what I've done since buying it:

    1. New gas tank
    2. New fuel pump and fuel filter
    3. New Air and Oil Filter
    4. Oil change
    5. New battery
    and a few other changes but that are not relevant to this issue.

    I have not ridden it much since I was having some weird issues with the front end. I decided to change the stem bearings.

    Before replacing the stem bearings the bike started up and ran fine. I started her up right before doing the stem bearing replacement.

    The only two parts I removed/changed while doing steam bearings was a replacement ignition switch and remove throttle cable assembly on handlebar to re-route the cables.

    Put everything back on the bike and it cranks but no start. Try some starting fluid and she starts fine.

    Checked fuel - OK
    Checked fuses - OK
    Checked fuel pump - she primes

    I started to removed the air filter box and check the injectors.

    Here is the when I try to start it with the injectors off the throttle body.

    Are the injectors supposed to squirt some fuel when the fuel pump primes?

    Does the choke look ok?

    It's my first V so I'm not very familiar with the bike.

    Any help would be greatly appreciated.

    Thanks and Happy New Year!

    How old was the gas? Did you check your spark plugs? Did sediment in the tank get stirred up between now and the last time it ran?

    Thanks for the reply. Brand New tank and fuel pump. I’m getting fuel pressure but she won’t run. Engine will run if I spray starter fluid.

    Can you see fuel getting sprayed down the throttle bodies? You can remove the secondaries if you want. Open the throttle while watching.

    9V battery and some carb cleaner can check injectors for opening. Easy to remove, on my L2 650 at least.

    Did you pull a plug and ground to test to see if you have spark on both cyl?

    It needs fuel and spark. Compression too of course.

    If you have spark then starter fluid and see what happens.
    If you don't have spark that's the ussue

    If it starts with starter fluid then you have spark and compression, which means you have a fuel delivery issue. You say it's a new fuel pump, but I'd start there.

    Plug the clutch interlock switch back in. Check the sidestand cutout switch as well.

    Check the clutch interlock switch....this is a common problem and an easy and inexpensive fix...you can short it out with a piece of wire to test it, if that is the issue it will run, though not well...was a $12 fix in Canada...I had 2 x wee stroms with this issue...other wise a great bike

    I thought that clutch switch only came into play when the bike is not in neutral.
    If it's in nuetral I thought it still starts w/o touching the clutch?

    not the case with my '12, but imo, that's the way it should be

    Why did you replace the ignition switch? Put the old one back in and see what happens. Good luck. Racer
