    Having long boney fingers is an advantage installing those header nuts....sausage fingers and you will struggle.

    I'm not sure why the plate is not sliding up to the studs and fitting for you. Ensure the pipe is fully in the head and rotate the plate and pipe if needed.

    For the nuts you mentioned you already have a universal swivel joint that you can attach the socket too...correct? Is it 1/4" drive like the following?

    Put that swivel and socket on maybe a 6" extension and try to thread the nut on by hand with the nut in the socket. You can apply some tape around the universal joint if yours 'flops' around too much.

    Otherwise, find someone with long boney fingers to start the nuts and finish with the universal socket. It can be a fiddley job if you don't have the experience. You english is very good.

    +1 on the 1/4" swivel. I also use one of those "spring" attachments and/or a 3" extension.

    And the plate don;t match up if the pipe is not alligned properly. with older bikes, the plate can misform/bend over time with the heat and constant tension on it, resulting in it only fitting one way around.

    In short: If it came off there, it'll go back on there. But not necesarily easily. :deal

    Hello fellow xrv fans.
    I'm an an American living in Switzerland. I have been here for a year and will be here for one more year. So far I have bought 2 Africa twins since I have been here. One Rd03 and one Rd04. Both were about 1600 USD. both were in great shape. My Rd03 is a square headlight version. Anyway, I am selling my Rd04. It just passed the Swiss vehicle inspection so its in pretty good shape. Not perfect but not bad. I will most likely list it locally soon but I would like to offer it here first. Any takers? Will post pics soon. 1900usd. 65km or so. 1991 wht/gen/red rd04 version.

    Thanks a lot GSPD750 and Squilly! I went to the hardware store and picked up the part on the picture you recommended and followed the instructions using the tape to stiffen it, worked out fine so big thanks.

    I have another question you maybe can answer, on the rear shock I see that it is possible to compress the shock which would result in a higher rear end, however can you adjust the shock when in place or do you have to remove it, adjust and then mount it?

    Thanks in advance,

    Br Markus

    I'm assuming you mean the adjustment ring on the preload. Yes it can be done inside the bike. Theres an adjustment spanner in the original toolkit, but I've always struggled with it (lack of room and leverage). I use a set of punch dies and a 1' hammer.

    But it would probably be easier just to take whole unit out if you've already have the bike stripped

    Gone!

    I have one in French and one in German. They're in the Fleamarket too.

    You pay postage and I'll ship them. Dennis.

    Hello all.

    I haven't been here for a while.
    As i was picking my groceries, i thought maybe i can put the XL700 injection system on my @. :D
    What do you think. let me hear your opinion.
    I think that the biggest thing to deal with is the fuel pump.
    (does the XL700 has a camshaft position sensor?)

    Cheers!

    Hello abat...you fell off the radar for awhile and I seem to remember
    the major overhaul you were doing on your AT. You were very close to starting the
    engine in your last post and you had it installed in the frame if I recall.
    You were deeper into that motor than anyone I had ever seen. Seriously...you have big balls...as I
    would have just bought a 2nd hand motor. It would be nice to know the outcome.

    As for your new question here...I can't help. But it would be cool if it happened. :ear

    Hi Abat,

    good to hear you are still with AT.

    Just like you, I have dreamed about fuel injection as well. But I too think that the accommodation of the required extra parts might work out to be quite a pain in the butt.

    Even if you find a suitable place for the required larger high pressure fuel pump, you would still need to find a place for the installation of a cam/crank sensor. Of course some vital parts of that setup might be scourced from the newer Honda Shadow engine, but even then you would need to find good placement for quite a few other sensors.

    For example while dreaming along, I could never envision, how I would fit the Mass Airflow sensor (I don't think any existing other bikes with Mass Airflow manifold would fit our AT). You would need to be able to make a custom intake manifold mold with the Mass Airflow sensor enclosed.

    At this moment I can only keep on dreaming. Perhaps some day someone will start a small production of a specific conversion parts kit.

    Andreas

    Hi GSPD, Hi A-Wind,

    Nice to read your posts. thank you.

    Regarding my engine overhauling, indeed, I have a debt to pay, and it will, i hope this weekend.

    If i'm correct, the XL700 throttle has all the FI sensors besides the cam posotion sensor.
    In my opinion, the CPS can be bolt to the engine in two ways:
    - Replacing the cylinder head from XRV to XL head.
    - Machining the XRV cylinder head.
    Also need to see if the cam pulser can be bolt to the camshaft.

    Because the XL and the XRV has different ignition timing, i need to figure out how the XL700 system can be adapted to the XRV engine with the ignition and fuel injection timing. more then likely i will need an aftermarket fuel and ignition management system.

    One more thing to think about is how to put a fuel pump to the original thank without leaks and in the lowest point. there are many small pump that can be used.

    Well, this project will take me some time to figure out if it is possible and some more time to get this done.
    Next week my @ is getting a service. i'll take some pic to think all possible problems i can encounter with.

    Cheers.

    Hi ppl.

    I had A crash my AT a few weeks ago. An was wondering If any of you know where I can buy a new faring set cheap? It is a model RD07.

    Abat, If you're serious about fuel injection for your bike, you should go to www.megasquirt.com a site for do-it-yourself fuel injection people.

    It is a site offering open-source design and guidance for modern fuel injection, offering design, guidance, kits and finished units for about any engine you can imagine.

    They are concerned only with the controller. The selection of sensors etc., are for you to choose and install on your chosen engine. They provide some guidance as to sensors that can be used complete with part numbers. The system is right up there with current design, for example it contains the required MAP sensor and all you need is to connect a tube to a vacuum source.

    There is an active forum too, wherein other enthusiasts get and give information...a great resource.

    Of great interest to we motorcyclists is their latest design, which you can read about at www.microsquirt.com . This ECU is about the size of a pack of cards. It is not available as a kit, but is surprisingly affordable. :ear

    Lots to read and think about......enjoy! :clap

    I'm excited to see your project Abat, past and future.

    I just corrected my post about sensorplacement. It is the placemet of the Mass Airflow Sensor that gave me headache in my dreams, but now I see bikes might run without it.

    As far as fuel pump, it does not have to be in tank. You can use an high pressure external pump too - just an idea.

    Following on to my post 12298, above.

    If you go to http://www.megamanual.com/index.html you can read a description of how this system works, in general terms.

    It's kinda heavy reading, for me anyway, but if you take it one step at a time, you'll learn how the system works, and what kind of inputs it can use.

    The Microsquirt unit is mainly just a miniature Megasquirt unit, built with ultra-small components. Because of its small size, there needs to be some changes to handle functions needing more current and/or voltage, which is handled with outboard accessory units as needed.

    For an idea of what's available and prices here's just one distributor. http://www.diyautotune.com/ There are others.

    For sure, there is a lot to read and learn, but the system seems to be quite comprehensive, and I have no doubt that it could be applied to the @. I'm not sure I have the dedication to pull such a project to fruition, but it has always intrigued me.

    I saw a mention of someone who has applied Megasquirt to a Honda VTR1000, which can't be too far from the RD07 engine. Hmmmmm. :ear
