    The fairings were really nice, other fairings I've bought have been pretty beat up but Henning's could be mistaken for new. Thanks again for your help!

    I think I can forget about the handguards for a little while. Today while riding on the highway the bike completely died on me. I assume its an electrical problem, because the bike didn't sputter and die, it just DIED. Like someone pulled the plug. The repair manual says possible faulty CDI, and I've read on this thread about people having problems with their CDI. I haven't taken it apart yet, but I wanted to put this out there maybe anyone had any ideas before I started into it.

    Try tapping the CDI with a screwdriver handle.
    Mine died a couple of years back, 88 US model as well. I bought a new one from ignitech.cz, You can probably find one closer but these have a 2 yr warranty.

    I was tapping it, smacking it, and cursing at it but it doesn't want to work. I thought they used to be really expensive, but I found one at partzilla for $96. I've had dozens of bikes and never had one fail on me. Do they fail often?

    No, If yours is original then like all electrical components they don't last forever, in this case we are talking about a 25 year old electrical component.

    First I would check all your electrical connections, especially the coil and kill switch before buying a CDI. I never leave home without a spare CDI on board. Did you bump ( shut off) the kill switch while riding??

    I assume you have the lights, horn, turn signals, starter working but no spark?

    Have you checked the ground/earth for the CDI? I also think that if the rev counter gives a slight jump when you turn on the ignition it is ok. Don't quote me on that though.

    Good thinking and although the wiring harness schematic shows the CDI as being grounded there is no independent or separate grounding of the CDI. The CDI ground is within the main harness wiring. Cleaning all the associated ignition connections should include the CDI connection which does have a ground pin.

    You could also have a bad coil or just a loose ignition wire to the coil, I think it is the black/yellow wire found in the left side of the frame near the front of the fuel tank area, check that connection.

    I would spend a little time making sure the kill switch is functioning right.

    Most CDI's that go bad usually start to work intermitently or cut in and out but it is possible for one to just die instantly.

    Seems to be common on these bikes now, Shindengen CDI failures be seem to be mainly dry solder joints cracking.
    I have one in the drawer with half the potting compound peeled off that I was intending on cleaning and resoldering.
    Just be careful the plugs on the replacement CDI are the same with sidestand cutouts etc.
    MIne felt like a new bike with the new CDI in it.

    I had just put new turn signals on so I originally thought I botched wiring somewhere, but I've gone over everything. Kill switch, ignition coil, all seem to be fine. No loose connections, nothing grounding out. It is strange when the bike died it just flat stopped running, it didn't sputter and die. And before this I have never had a problem with the bike starting or running. EVER. Its an old air cooled Honda, they don't die. But I'm really lucky it happened a few miles from my house and I was able to put the bike in the truck and get it home. If this had happened on a long trip I'd be screwed. So I'll either buy a second CDI, or just open up mine and fix it. Here is the link to the CDI:

    good luck, hope that solves your problem. Great source for parts, been using them for several years.

    Get a new one and repair the old one as a spare.
    Peace of mind is worth it.
    The old one has lasted two decades so they aren't that fragile.

    I don't want to run the risk of any of this happening again, so I went for the trifecta: Ignition coil, CDI, kill switch.

    After this pic I tried to get closer and the trail got ALOT more difficult, I did fall over but he crash bars saved the day!
    Not to self giant rocks are hard to drive on!

    [​IMG]

    First impressions are the bikes a guddun!
    400kms and no probs so far, it can off road very well if a bit heavy!
    I am not the most talented off roader but how the hell do you drive on just rocks! Big ones!

    Now tommorow I will wash the bike and tighten the saggy chain!:1drink

    I started riding dual sports after 25 years of only street bikes, so I'm no expert. This page was a good source for me:

    Slowing down and then gently accelerating through an obstical works best for this old rider.

    Good to know your guards work!

    I'll keep the old parts, and use them as spares I guess. But now she has to sit apart until the new parts arrive. :cry

    That looks cool, I like the NXR750 version as well.
