    p3dro, did you get your bike out of that place and get your electrics sorted?
    Cheers.

    G'day to everyone and his dog. The site has been interesting of late. Good to see people helping people. I haven't had much to say but I've been lurking.
    Been spending a lot of time on my '95 XV1100 and it's been great. The last two times I took the DR800 for a ride I fell off. True story. Two rides, two offs. Both times while moving backwards into a parking space. That's bad enough and god only knows so, so emarrassing in front of people in the car park. But each time it did a little cosmetic damage and had to be touched up. Luckily I had some paint left to fix it. And remember everybody, my bike has been lowered 70mm so both feet sit flat on the ground. Perhaps I should have left it standard where only my toes touched the ground. I never fell off it then! It's mystery and one I hope doesn't repeat again.
    Keep well and ride safe.
    Cheers.

    Howdy guys,

    A little update on my progress:

    Had loads of fun with the carbs on Saturday, boiled them and made a nice soup. Sprayed everything with carb cleaner and let it dry. Next morning I was scared to bits, since I've left everything on the balcony in the open (and I live on the 6th floor) and a windy storm came in. I was lucky to find all parts smashed around in the corners of the balckony, nearly lost the floats...
    Anyhow, I have discovered a few things:
    one carb:
    [​IMG]

    the other carb:
    [​IMG]

    A keen eye would notice straight away that the needle is not on the same level, and the thread of the needle jet is damaged on one carb.

    And vuala, upon a quick check, the needles really aren't leveled:
    [​IMG]

    And the cause is this little washer:
    [​IMG]

    Comparing it to the other one, this one loocked odd, nearly like a diy washer which was slightly too big to fit into the place it was designed to fit in the slide. I polished it slightly, and got the needles leveled. Needles to say, this caused one needle to be raised by a major level, causing the main jet to work on iddle...
    1 problem down.

    Upon further assembly, I have re-checked the main air jet and pilot jet - positions 34 and 35 (the 2 small jets on the intake). I had the feeling that at some point perhaps during my 52nd carb assembly i had them misplaced. Checked with the manual, got them definitely right this time.


    And voila - it runs.

    On a test run in the forest I remembered that I had troubles with the battery - damn the beast is heavy.

    Mot'ed, insured, commuting today. Hay!

    Thanks to all the help guys, much appreciated.


    I'm going to start another thread on how to jump-start the sr43. How do you do it?

    EDIT: i'm still not 100% happy with the carb settings, perhaps need to adjust the needle/mixture a bit as it feels sluggish on heavy acceleration. the sound goes very deep and it accelerates somewhat slow.

    Wundis glad you are making progress,
    In the first pic the little wire bit that is on the end of the float needle is how I would put it on , in the second pic it is 180 degrease arround.
    Allso one little wire bit is different to the other, so probably one float needle is original and the other one after market.

    Well, float level is still a mistery to me. It is set correctly right now, I've got 0 everywhere, however the way they are set is unsatisfactory to me.

    After playing with the OEM replacement parts for too long, I was able to set one carb correctly, the other one had to accept the old needle valve with the stronger spring. However, whilst the float level was ok (by checking with the clear tubes), the float height (by measuring with calipers) was way over 14,7.
    I have ordered some aftermarket needle valves just to check what strength they are, perhaps after all my float assemblies are old and are prone to sinking... if this is the case i'll just ride it till the winter and then do a re-check along with some esthetical repairs.. .

    Hi people,

    I have recently gotten a GPR exhaust for my DR800. (Model GPR 12)

    But I got stuck getting it certified as road legal.

    The man at the inspection center said they need a 'Full Sound Test' of the exhaust for the DR800. It's suppose to be a document showing the decibels emitted at various RPM up to 75% of the max RPM.

    Does anyone have the document or know of where I can get it downloaded online?

    Despite of bad jetting we had some fun last weekend in Estonian countryside with my friend on BMW G650 XChallenge and me on DR Big of course. Some gopro still shots:

    yesterday.... got my 107mm hessler piston and rings seals etc. It's too pretty to put in my '89; but she deserves it. Sorry, no pictures until friday. Don't remember the cost, ordered in late ' 12. But no worry: bought new restauration project, '62 model brick house with carage! for my DR! I'm happy man now :) So mostly HILTI singing now...

    I was also told by other allroad riders not to change the bike, because it's too much related to my persona....

    They're Just bureaucratic wankers. Put the old muffler back on, get it registered then put the GPR back on when you get home.
    Cheers.

    You can only adjust spring preload by turning the spanner nuts on top of the spring.

    Hello guys,
    been just 3 days or so off and you have been so busy!
    Wundis, great you're making progress!
    Ausibatla, that's the reason why I always get off the bike to push it back and forth.
    Mait, you make me envious with your riding-skills! Seeing you flying that big duck in a manner I never could do! Been to sandy Mecklenburg-Vorpommern in the east of Germany 2 weeks ago and got the old girl pretty dirty. But I don't think that I hit more than 60 km/h in the sandy passages. Hard-packed gravel is easier for me. Maybe because at 56 I'm an old fart and afraid of hurting myself. But it's been fun, nevertheless!!! Some pics are in the link of our Big-gathering I posted a few days ago.
    Still have to read through the last days, guys, but I didn't want to forget commenting anything of the first things I read!
    Kind regards, Bambi

    I know they are.

    And this comes from the country that bans chewing gum and guns, even toy look alike ones, where vandalism (ie:graffiti) carries a mandatory canning penalty. A country where a person has to apply for a permit and call the police to inform that he and his friends are staging a peaceful demonstration if they are not happy with the policies. And here's the best part.... Most people here just keep quiet, because to do so can get a guy imprisoned indefinately without trial on the basis that he is inciting a riot.... :oscar

    The bike is road legal, it's the pipes that are not.
    But the good thing about the GPR is that the bike runs much smoother with it and there is no lessening of power at 2.5-3k RPM when compared to the stock pipe.

    Hi everybody!

    First, to introduce myself: I'm from Slovenia, currently without a bike, but and I intend to buy a DR 800s (1992).

    I have been reading this thread, it was really helpful to me and I learned a lot about DR's. I could't find "buying guide" for DR 800, so I would be very grateful if you could give some clues what to check in a used DR 800. This is the link to the bike I want to see (the only one for sale actually here): CLICK

    Thank you and best regards,
    Marko
