    At least you know there's oil in there :evil
    I have replaced mine twice now and it still weeps a bit. not a hard job to do. I have learnt to live with it.
    I have a question for the group....
    How do you guys keep your bikes so clean ? I cleaned mine this morning, after another dusty ride and it still looks crap compared to others on this thread.

    Ztaj, its called elbow grease, diesel and worn out paint brushes. tooth brush is good allso then slight preasure wash, then pinch a couple of tea towels when the cook aint lookin and dry the thing .
    If you don,t dry it they look like pox.
    you can wd40 after woods and wipe down as well and spray your spoke nipples as well and this will stop the rims from corroding too.
    Now the plexus spray for your plastics and buff and your done.:lol3

    Shannon my 4 don,t leak and these seals are easy to get at the local shop, remember to line the shaft when assembling and get a new side cover gasket as well and don,t use gasket goo just oil it first.

    Compressed air is your friend when trying to clean the bike well.

    Blow all the dust and crud off before washing, then wash and blow it dry.

    The high pressure air gets all the dirty water out of the crack and crannies (all motorcycles have lots of these).

    That being said, it's never a good idea to have your bike completely clean since it alwlays makes one think twice about exploring that dirt track or taking the short way round on a trip.

    Some bikes like the Bigs look better a bit "used" unless you have a black model set up like an SM bike that looks like it belongs on the pavement only and there's lots of chrome and Yamaha bits on it :D

    IMHO to be honest I saw it many times (my french friends have sent it to me when I bought DR) and I find it ugly, excessive without function, overweight and pointless.
    None of DR issues affecting it as road bike addressed here except perhaps front forks and brakes. And installing SSS onto pathetic DR swingarm mounts just adding up to it. And DR 55 bhp (at best) motor does not need such brakes and forks actually.

    Creator clearly was under influence of Ludovic Lazareth bikes but without his level of design skills.

    When it comes to road-going DRs I think nothing is better designed than famous Harris 855 bike (leaving aside proper race mono bikes from UK and France)

    Sorry you blokes my internet has been down because one of the box thingy,s on my satelite dish got some water in it and I was fixing it tonight in the dark.
    Cleaning your bike has its rewards, all will be revealed soon Raymond :lol3 .
    Shannon eagle screens on there web site I thought only stock screens but may offer different tints if you ask.
    Ztaj, If you leave the dirt on it has mild acids in it and thats what takes the shine of the alloy and plated screws and bits, have alook at your spokes I bet they have gone nealy black :D

    PS, tall screens are a shocker if tinted to dark, because you car,nt see in front of you when in the scrub and who wants to stand up all day, not at my age :lol3 .
    I fitted a lazer can second hand one tonight to the new blue bike and now its bloody midnight again no rest for the wicked.:rofl .

    Its a matter of taste I guess,but you got to admire the work put in.

    Though I also thought it was a waste of Chassis as a Stock DR Isn't to shabby at coping with it 50ish HP

    Stock DR Chassis have EXCELLENT geometry, I am referring to SSS conversion - as you know with SSS torsional force transferred right at part of frame which in DR is totally not designed for it. E.g. conventional swingarm will work much better on DR than SSS.
    Plus this conversion messing up geometry of DR. I know it because of popular conversion of VTR1000F with VFR swingarm. VFR arm is longer than VTR, thus wheelbase gets quite a bit longer. On DR difference even more serious - so, with this swingarm and forks his bike geometry got fully changed. Now it is slightly cut down wheelbase in front and extended at rear, so even mass center moved a lot.
    What I mean is that it won't suprise me if stock DR on 17" wheels with sorted shock and forks will easily outrun this monster on curvy road. Which I believe you have proved once :)

    Thanks for the advice Bluesman
    Mine is a SL model year 1989, the first DR800, which has the body of a DR750, but the increased bore and stroke of the DR800. So it has no auto decompressor, I manually held onto the extra lever above the clutch lever to activate the decompressor everytime I try to start the engine.

    This is what we did, we opened up the left cover and took out the magneto coil and sent it for rewrapping of the copper wire, took out the spark plugs and the caps the plugs were inserted to and placed the wires onto an unpainted bolt on the chassis, no spark. We also checked for current coming out of the coils to the CDI with a meter and there was current going in, but none coming out from the white wires of the CDI, and just to be sure, we dissconnected the CDI and crossed the wires from the coil and there were sparks meaning there was a current coming from the coils.

    I even tried hot wiring like Zappa adviced, I diconnected the ignition couplet to diconnect the white and black wires as well as the red and orange then using 2 pieces of extra wires I connected the red and orange together and got a neutral light without using the key, but still no sparks when I pressed the start button. Sigh!

    Right now I am at a lost, I have run through the list
    1. Neutral light on
    2. Decompressor on
    3. Side stand wires connected (side stand kill-switch was removed)
    4. Emergency kill switch on the right is off.

    Is there something I am missing here?

    I feel like just rebuilding the bike and replace every worn out part and have a piece of mind now. sob sob! :cry

    Silent Hunter, right hand kill switch should not be in off position, it should be pushed down to bottom position that sais run.

    D'oh. Well spotted. Silent Hunter, when you say "off" you mean "Run"?

    I don't know whether it's "Run" or "off", the lettering were too faded to be seen :rofl so I tried both positions.
    In the emergency kill switch on mode, the starter didn't even crank when I pressed the button.

    When I tried the kill switch button off, the bike's starter cranked, but no sparks. :(

    No, I didn't short the clutch because I don't know which wires were the clutch wire sensor wires.

    Ok trying to help hear, just make sure the kill switch is PUSHED RIGHT DOWN.
    and maybe spray some WD40 or CRC in on the decompressor switch on the handle bars BECAUSE THEY SOMETIMES STICK WITH CRUD from previous lubrication and dust.
    Can you check the pick up coil itself.

    It has been interesting for me now having the KTM to compare with, I believe with the same size rubber and perhaps a stiffer fork the DR would go blow for blow (though) you cant give away 50hp and expect to outrun the twin in the more open stuff, and on the Gravel I think the DR would is a much more controlled and comfortable proposition as the 950 is a mad thing:eek1 in the loose metal and possible even dangerous until one learns to go easy on the throttle
