    By any chance, did you buy that new starter relay at ebay? If so I suspect that your chinese relay is not working. You can try this by disconnecting the red cables from the relay, turn on the ignition and then (with isolated grips!) connect the red cables directly - if the starter runs, its the relay. If the starter won't run, the starter is defect.

    As for the high fender - don't forget that the RFVC engines are already running pretty hot and a high fender is thus not ideal in that regard, so make sure that there are at least some vent holes.

    Looking great - and I'm glad that the parts of my dommie found a new use.

    Well, the starter relay is ok, I 've checked it. Another question, should the starter move freely by hand? I have torn down the starter, cleaned it, but when I reassemble it, and I tighten the bolts I can't move it anymore,... I think I have reassembled it correctly, why is it stuck? Should I change it to a new one?

    Something is wrong if the starter will not spin by hand.
    Check all the washers are in place and nothing is binding when you re-tighten the screws.

    Hello, my friends. Well, I have some starting problems :
    - I have checked the ignition, the spark to the spark plug is ok and going strong,
    - I have checked the starter and the starter system, everything is ok,
    - I have used 2 new batteries to try to start it.... so there is no electrical problem,
    - The starting relay is new,
    - The carburetor has fuel since I bleed it,

    Well my problem goes like this, with the spark plug out the engine revs ok, when I put the spark plug in it's like there is too much pressure in the piston chambers and I won't revs, our it revs very hard and sometimes, without the spark plug in everything is ok. What should I check next?

    Check your starter wire connections. I had a same kind of problem with my Ducati once.

    I know this isn't the Flea Market but I am just seeing if there is enough interest in DSC03951.JPG posting all this plastic. It would take a fair amount of time and lots of images of the fronts and backs plus describe all the condition details etc. If there is no interest then I can save myself a lot of unnecessary work. Lots of other NX parts as well. Thanks

    Found the old FAX relating to the engine cutting out at idle. NSX650.jpg

    This is fascinating. Does anyone have any thoughts on how swapping in a hotcam would change this? I've gone through just about every imaginable way to solve the idling issue except for this one...

    Any performance cam lowers the actual compression with it's longer duration and valve overlap. The decompression system serves no purpose on an electric start model anyway.

    Thats the thing, this engine in the EU and RoW models of the NX had a kicker on the J model.so I guess it was necessary to have that in that case and they just continued with it because it also gives the starter an easier life.

    Hi all,

    Do you use your domie as a daily commute? My normal consumption is around 5,7L/100km so not the best bike for this type of ridding.

    Should I take the bike for the next level and use it only for trails or keep it "Stock" and continue to use as it sits.

    I was thinking to rising the handlebars with a 3cm to 5cm raisers, Will I have problems with length of the cables? ( throttle, air, etc )

    Thanks

    The aerodynamis of the XR650L and my tall ass are a lot worse than the Domis and my XR gets by with 5.0l/100km while not being easy on the right wrist.
    Check your carb settings.

    I'm a bit confused as well. My understanding is that a faulty decompression system can cause the idling issue. By swapping for a performance cam, one would just be eliminating that possible break point, right?

    Yes and obviously you gain performance from the cam as well.

    Have you tried cleaning the small holes in the carb body? They are just inside the carb butterfly and are in a cross pattern, on the California model carb I have there is also another one next to them that leads to a brass nipple that exits between the pilot jet and idle screw and is connected to the tank breather through a charcoal canister.
    These holes are tiny the same size as the hole for the pilot jet hole.
    I saw a post on another forum where a guy cleaned his out and reported a much better idle.
    This is what the they look like.[​IMG]

    Hello my friends, for adjusting the valve clearance, I need to make sure that my piston is in the TDC position (Top dead center), how can I do that?

    Undo the plugs on the side cover you will see a big plug and a small one, the big one is used to turn the engine over anti-clockwise.
    TDC is when you hear the decompressor click, listen carefully. If you don't hear the click go round again.
