    FINISHED! A BIG with small fuel tank and without "beak's duck"

    First... of course... sorry for my bad english... OK? I hope you can understand me... :-D

    I do not know if anyone will remember that in last October 2012 I began to think transform my Suzuki DR 750 Big on a different bike, closer to the beginning of Trail concept of the 70's. That began a first search smaller and light fuel tanks to remove some weight and change the bike image. This was my post: http://advrider.com/forums/showthread.php?t=362489&page=918

    [​IMG]

    With a Merlin Dg11 500 fuel tank (a gift from my friend ManoloMK10) I started a search of different pieces: front headlights, fenders, seats, turn lights, plastics... and, of course, people to help me in the task. To all those who helped me in something I can say only ¡Gracias! Thank you!

    [​IMG]

    Well, with all in position, I needed start and work... two months and a half, but the bike is finished. Perhaps I can write all in english ...really in MY english :-D ... but I wrote all in my blog and I think is more easy if you use a automatic translator at your language. If you have any problem, ask me... and I supose I can answer you :-S

    Long version (16 chapters, giving reasons about the transformation, pics, sketches, testing differents fuel tanks; the transformation; and pics about the final bike) El Proyecto LS (The LS project)
    Medium version (11 chapters, the transformation and pics about the final bike) LS project, part 2: The Garbí
    Short version (2 chapters, pics about the final bike) ¡¡¡Terminada!!! (Finished!!!)


    Just ask two things:
    -Opinions. Worse or better. Really I think this is an unfinished history... I can improve very much things... but I need your opinions for this.
    -Wide distribution. If you write about my bike in other forums, please write here the link. I want very much opinions!!! :-)

    Thanks for your time... and I repeat, sorry for my bad english... :-D

    Just a question, has anyone tried changing the rear wheel of the DR800 to that of a DR650?

    I am thinking of doing that, because it's hard getting spare parts for this bike over here.

    Try a cross check with 91 dr 650 for SR 42/89 and SR 42/90 using CSMNL.
    OR try All Balls for bearings

    Miguel, the bike is looking very good. In general I like the original design with beak and large tank but yours is appealing, too.

    float valves leaking. replace these.
    turn your fuel off when you shut down the bike, that way if they do leak your engine will not flood.
    plenty more info on this further back in the thread. suggest a full rebuild of the carbs when you have them out.

    What went wrong?

    Gravity...and.....Twenty year old O-rings and/or float needle valve and seats

    There is an O-ring around the needle valve seat (the brass bit) that seals it (or NOT in your case) into the carb body. So even if the float valve and seat are good you might leak fuel above this valve.

    There is another one on the plastic float valve "tree" and yet another under the slide guide.

    In short, replace all the flexible sealing bits on both carbs and you'll be OK.

    The fuel valve on the tank is there for a reason.

    Yes, you can get the kit from Hessler. You can also get the standard Suzuki parts from a dealer. Stefan has a very good reputation for quality bits and is just about the only large shop in the world who still goes nuts for these machines.

    Robmoto, really thanks. Curiosly when I was thinking about this transformation, was looking for pics about it around the world... and the better changed Big for me is your "black Supermoto"... really pretty. I was writting about:
    http://www.voromv.com/2012/09/con-el-de-plata-en-el-bolsillo-29_22.html

    When I saw your bike I thought "Really I can do it"... and I have now my different DR 750.
    Robmoto, you was my inspiration... thanks to you.

    Thanks Mait... and a secret... I like more the original design too!!!! But now I haven't money for another bike... and I NEEDED another bike, another illusion. Well, now I have a different, unique, bike... MY bike.
    And is a DR ...

    Howdy,

    Could anyone confirm the dimensions of the oil seal by the oil pump on the clutch cover ? Bottom right in the pic:

    Hi Miguel, I can not take the full credit of my 800, a lot of mods were already done to the bike, but when I bought it , it was in very bad condition, I just kept throwing money at it till it was right and rebuilding it changing things as I went along it owes me 12k :lol3.
    Funny thing is I only ride it a couple of times a year or so evan though it goes like the clappas.

    Alas
    part 09282-16002 dimensions 16x30x6. Not sure why, but it seems i wasn't able to find it in the parts manual, or was looking in the wrong place.
    It's a shame that no local oil seal supplier has them, waiting for an original part to arrive means a big delay in my plans :topes

    EDIT: ok, I must edit my reply, turns out, the big delay isn't that big right now - fast delivery is 1 week from a wh in Germany. yay.

    It is very rare for there to be an issue with a float seat. Usually the float needle and/or the needle seat o-ring are at fault.

    Also make sure that the float itself doesn't leak, i.e. that there's no fuel inside the two chambers. You can either hold it up to a light, in which case it should be evident if there's fuel inside, or you can put it in a container of liquid and see if one side sinks more than the other.
    Agreed.

    Regards,

    Derek

    I have three different rebuild kits in stock for these carbs, one for the '88-'89 DR750 & '90 DR800, one for the '91-'96 DR800, and one for the '97 DR800.

    Regards,
