    Buggles, Welcome, will list you on post 1, 62hp is a nice helthy amount but I think the non owners wont realize how much torque comes with that, these bikes really pull from low down on the road I often only use part thottle even when passing

    Nave, dont think my DR can jump like that,
    but it can do this as per attachment from post 30

    Got it on the rev limiter at one stage ( aprox 8500rpm ) which is easy to do on the beach and especially with loud pipes which free up the engine a bit.

    Manos, your NX project sounds interesting I have 1 with a 10.25/1 piston fitted and it goes a lot better than standard my worker who rides it is always doing wheelies on it now

    bluesman, turbo you say, hmm, also this is from a web link you posted earlier as molgan wants more pic's, some of you may be able to relate to this, DR Bigs reguire that you look before you leap cause near 200 kg is hard to move when its like this

    Nothing much going on here, so I'll just post a pic of my DR that I now have restored back to (almost) its original shape:

    I like the big singles but they are too hard to find in the US. Is the basic motor similar to the DR650? I thought there was a kit at one time to bump the 650 up to 750 of so...

    My dream is a DR650 bored out as big as I can go in a SR500/SRX6 type of setup. A huge roadster single!

    Might be hard to find anyone thats used them, would he give you any referances or contacts,

    Usely Carbs work best when other work is done such as pipes and cam cause then the motor can use the extra fuel, since you have pipe, Id quess youd gain about 5hp from carbs, bluesman may have some thoughts

    Colleagues, I am happy to report that we just came back from our tour to Norway...10 days alltogether, me + my wife + luggage, 800 km through Germany (motorways), 350 through Denmark (motorways, boooring), ferry (that's 2 days wasted to and 2 days back) before reaching Norway. Approximately 2500-2700 km in Norway in 6 days on different, mostly small and badly damaged roads.
    DR did fine, except that cheap bolt I used to tie gear lever on shaft snapped and I lost gear lever somewhere on German motorway 300 km from home. That'll teach me to watch what materials I use when working on bike. Replaced with more-less suitable gear pedal from Kawasaki dealrship nearby...lost 2 hours.
    And another thing - for some reason this time my DR used a lot of oil for 5000 km. Was not the case right before, but before I did not ride it 2-up + 30 kg luggage for 5000 km. Not sure why. No smoke, no loss of power, no nothing...not sure where oil goes. Perhaps a lot of lane splitting in still traffic in Germany to blame. Now bike is at 86000+ km on the clock 10 000 + of which are mine. Going to monitor it a bit. Next time we will go straight to northern Norway as this time we rode lots of roads just up to halfway between Bergen and Trondheim. In a word: it was great and I like northern and mountain parts better than fjords.

    Pictures being sorted now :)

    Well, here is all story about oil.
    When I left I had halfway between F and L marks, used always Castrol GPS, 10W40 on all my bikes. Bike did eat a bit of oil, but even less that usual for big single. Let say from full to halway mark in 3000 km. I had 0.5 liter of same oil with me to add to make it full. So - that 0.5 liter do not count, but I only added it when in Norway - see below.
    First day halfway through Germany it is hot and we hit dead traffic jam - autobahn totally closed because of truck accident.
    I filter 20 km through dead still line of cars, engine head temp. shoot up to 176 Celsius (it is not oil temp, it is head under spark plug, so 176 is still OK). Before trip highest temp I did hit was 165 Celsius in offoroad ride.
    Then we ride remaining km thtough Germany, Denmark and I never checked oil.
    First full day in Norway we go for a challenging ride around Lysefjord - mountin passes, twisties, haripins etc. etc.
    That evening I did stupid thing: I checked oil level on cold bike, after it stand there for like 4 hours. I see 0. I mean - I see almost no oil, it is just touching bottom of measuring stick. Despite head temp was totally fine all day. Panick attack. Poured half-liter of that original Castrol oil I had with me in. Touching low mark. Ran to nearest fuel station, bought Shell 10W40 half-synth auto oil. Poured 1 liter in. Oil level (on cold bike) on top.
    From that time constantly checked oil level with totally mysterious results. One problem - bike was jacked up with preload at rear to cope with luggage and passenger, when we both on bike and luggage on - level seem to be higher on stick. When I measure on empty bike - L level. Then on hot bike oil seem to be OK, then I forget and check again on cold bike - low level.
    I started to go mad really. Riding was difficult, lots of changing rpms and gears, twisty roads, really bad surface, fair amount on 1st and 2nd gear crawling.
    In Norway Bought another 1 liter oil. Statoil 10W40 half-synth for cars. Close to end of journey gradually poured it in because level was L again, but every oil check was that mad "measure 5 times, get different results. Before hitting ferry back oil level with all I poured in was full mark.
    On way back through Denmark and Germany (1100-1150 km) had another panick attack and poured about 400-500 cc of that usual on German oil stations "no name" 10W40 oil in (quality there usually good even for no name, and it is not particularly cheap) so it was top mark again. Now bike is cold and still jacked up and oil is a bit above low mark.
    Today I am going to change oil and filter to original Castrol GPS (now called RS4 - they just changed name).

    Look forward to Pictures I have a few post to

    In regards to Oil consuption youl just have to start from scratch and check it under normal running conditions, I would think 3000ks per litre would be acceptable at your Ks and as Oil gets dirty it will use it a lot quicker

    Colleagues,
    Quick question.
    I am looking for quite aggressive (more than Mefo 99) tyres for my DR. Objective: 200 km to the meeting point on motorways, totally offroad riding for 1.5 days, 200 km back.
    I did it once with Mefos and found them to be too bad in mud (rest is fine).
    Fellow DR owners from Dutch club suggested Pirelli MT21. Somebody else suggested TKC80. I know TKC80s are better on pavement, but are they good enough for mud? And opposite side: are MT21s that scary on pavement that I will kill myself during that "paved" part of ride? Anybody tried to run MT21 on DR?
    I need tyres that would give me more confidence in wet stuff (Mefo's just s..s in the "wet" offroad) but will not kill me on simple ride to meeting points on paved roads at about 120 kmph motorway riding...
    I heard horror stories on MT21s like "on pavement it is like riding on bearing balls" - is that truly THAT bad?
