    if i could have only one bike, this wouldn't be it. i love my dr200, but unless you are willing to travel slowly it's not the best bike.

    i have a 39 tooth sprocket to install to get the rpms down at highway speed, but i don't have any illusions of interstate blasting once it's on.

    and like viverrid says, if you're taller then getting up on it will be a problem. i'm 5'4" and it's almost a little short when i stand up on it (which isn't too often).

    I've been wondering about that myself a little. I don't have anything in the 350-400 cc range. So far, I have decided that if I could only have one bike, it would be the 650 thumper. Alas, while the 200 is a nonpareil commuter/utility/light-touring bike, it just doesn't have the long-distance capability of the 650. If I had a DR350, maybe that would be my favorite.

    i have a couple pair of cycling shorts.

    never worn them on the dr, but they are ok on the f650.

    don't spend a lot of money on cycling shorts if you buy them. i have a cheap pair and an expensive pair and there is really not much difference.

    and, uh, boxers don't work well under cycling shorts. an unfinished basement is generally preferable.

    My 200 has picked up a little stumble. If I hold the throttle a little above idle, for example, it'll run a little unsteady and cough once in a while. Sometimes at idle it'll cough and die. I'm going to check the valve clearances first, then if those are okay, which they very likely are, I am thinking some kind of carb glitch.

    Any ideas? The air filter is clean and it has a new spark plug. It's got 10,310 miles on it. It starts beautifully.

    probably right on the carb. as a big believer in better living through chemistry, i'd run some fuel system cleaner in a couple tanks before i started tearing things apart.

    could be funky gas, too. i've had a couple suspect tanks in the last year or two.

    Good idea. I'll run a little Seafoam through it.

    The carb seems to have cleared itself, without adding any new gas. Maybe there's a speck of debris floating around in the carburetor.

    The DR200 was sweet puttering around today in the 90 degree heat. Couldn't do without it.

    glad that worked itself out.

    i've had a couple of instances where i filled up, then noticed that the bike seemed a little weak(er than usual). we were in the u/p last year and got some gas that caused 2 out of 3 bikes to sputter a bit. all the bikes were fuel injected, but one person either didn't notice, or maybe the power commander on her bike compensated for it.

    and at 90 degrees, i need a bit more speed than the 200 can provide to stay cool. :lol3

    i haven't installed the 39T sprocket yet (lazy, so lazy). i rode to the east coast of michigan on dirt today, and was so beat i decided to ride back on more paved roads.

    now that the bike is run in, she runs pretty well at 55. i kept up with highway traffic for 15~20 miles before turning west and plodding along at 45 again.

    the trailwings seem to do pretty well as long as whatever you are riding on/in isn't deep. 3~4" of sand is brutal, but leaf-covered trails are a snap.

    It came back. When the bike is fully warmed up, it idles nice and steady, but there is a spot just above idle where the engine is unsteady. I took the carb completely apart and looked carefully at all the jets (took them out) and can't see any problem, and put it back together. I put a couple ounces of Seafoam in the gas and we'll see how it goes. There's room for about a another gallon in the tank. Tomorrow I'll top it off with different gas and see what happens.

    Sounds like a fine ride...the east coast of Lake Michigan and back is a good trek for you, if you live there in the thumb. The DR200 will go 55 just fine, even for me at 200 pounds, as long as there's no head wind.

    Edit: Oh, I see you went to the east coast of Michigan, not the east coast of Lake Michigan. Nice ride.

    My wife and I rode around in the country on our 200s hunting for raspberrys today. They're all just getting perfectly ripe now here. We found and ate many, many handfuls. Man, I'm glad we have those 200cc bikes to go exploring.

    Here is my daughters DR200. I have removed all the rubbish from it to lighten it up for her as an off road bike. She rides it very hard and I have fitted a Michelin S12 up front and a Metzeler 6 days rear tyre. I have even ridden the bike and although down on power, thought it was fun.

    As many of you know I'm most active on the Minimalist Tourer thread with my DR200SE. I've recently gone from a 15:42 final to a 15:40 in the effort to achieve optimal performance for overlanding.

    Found that the 40T wheel sprocket provided excellent performance at 45+ mph with a reasonable rolloff; but, there was a 20% loss in fuel economy (105 to 81 mpg). This test was performed with panniers fitted and figure total load was about 210lbs with rider and gear.

    Where the bike could cruise at 4500rpm before with the 42T (40-42 mph) it needed at least 4900 to settle down with the 40T. Was using Shell V- power as fuel nevertheless this test verified how important W-Power (wind) is on small engines and economy.




    Mick;

    My 200 started off as my daughter's bike but when she opted for a Kawasaki our 200 sat until I started riding it after I broke my leg and couldn't handle anything heavier for a while. The 200's size and weight was so similar to my 78 Yammie IT175 (still have) it was a match. I have other bikes but really prefer the nimbleness of smaller lightweight bikes.

    I see your 200's come with a kickstart which we do not have offered here in the states. Do you have someone in Australia that offers an online microfiche or a parts contact. I would like to fit that to mine. Not sure if I had the part numbers that I could order here or if I would have to order from an Australian dealer.

    Thanks.

    Steve,

    My father has access to some wrecks. I will see if he can get you the gear.
    Over here they have a heavier model called the Trojan as a farm bike. We did have another one as well, but it was the button only. The kick is great as it may be some time between rides for our little one so being able to kick it is handy.

    I will see what I can come up with for you.

    Thanks for the consideration. Not looking to give you any work on this issue. Just pointing me to a source would be great. :freaky



    My Suzuki RGV250 is an Australian model; wish we could have had that stuff here. :cry


    Another great ride ...:ricky ...tell us about yours.

    Just Ride and Steve GS have both gone to 40T rear sprocket on their DR200s. Just Ride is a self-proclaimed 200 lbs, while Steve GS is 140 lbs. Just Ride sees quite a performance improvement, while Steve GS is not so sure, it seems. Just ride expects an improvement in gas mileage, but Steve GS sees a 20% drop.

    I, too, had thought to go to a 42T or 40T, maybe even the easily found 39T for the rear. Now I'm thoroughly befuddled. I hope Tweeker43 can get his 39T installed soon and clear things up a bit.

    Tweeker, the pressure is on.:deal



    I somewhat expected the drop in economy.



    Once I took the rpm readings and saw the a 5th gear cruise at about 4900 I knew there would be a drop. How far I was not sure. The increased wind load is the major player here. The only other variable is the Shell V-Power that I was running in this tank.

    I hit reserve at about 240mi and I'm still on reserve at 290 without a side flop to dump the right side fuel to the left (petcock side). I'm going for range mileage points to overall reserve, left, and finally right to get absolute range. Let me also note that the first 100 miles on this tank were with the 15:42 final, that was figured in when the fuel mileage was calculated.


    Klay and others have done some tripping on their 200's reporting mileage in the 80's and they will run their bikes at a higher rpm than I do so I think I'm right in the mix.


    With the 15:42 I try to cruise at 4500-4800 rpm and if I hold will always pull about 290 (about 105mpg) before hitting overall reserve point.

    I've decided to go back to the 15:42 because I'm only 2 months away from my departure (James Bay Road) and need to sort out a few things. The trip length being 2500 miles I really prefer the 40-42 mph cruise (easy on engine and less wind resistance) to 45+ though it may take longer and the battle with traffic at certain points may be more of a challenge.

    I found that lowering the rpms at a given cruising speed took too much power from the engine for a person my size (200 pounds) with camping gear on the bike. I can get 70 to 80 miles to the gallon, but only if I keep cruising speed between 30 and 40 or so. I invariably push faster on a long trip. Good thing the DR200 has a bigger gas tank.

    I have a 16 tooth front sprocket for the 200 if anyone wants one.

    Steve, maybe you could think about putting one of those orange flags on a whip on the tail of the bike...then it would be clear to traffic that you're moving slower, or they might even think you're on a bicycle.

    I just kept to the extreme right when traffic came up behind me and then I would pull over if necessary to let traffic by. It didn't feel like too much of a problem. But of course that was rural Minnesota and North Dakota.

    Where was this thread when I still owned my DR.

    Now I regret selling the damn thing.

    Now I am starting to get nostalgic :cry

    If I remember right you were running the 15:45 final (OEM)and it has a sweet spot at 37 mph indicated. With the 15:40 I tried, anything below 4900/45mph/in 5th (GPS) you could tell the engine was lugging, it really needed to spin up. This pup only has so much power, if you need more get a bigger bike. However, it gave perfect rpm running points at 25,35, and 45 mph (GPS reading).

    Our 250 Ninja is the same way; with a 15:41 final (I think OEM is 14:45) and limiting the rpm's to 6000 (60 mph) the darn thing will get 90mpg. If you like to play in the 7000-10000+ range you are down to 80mpg or less. Though mathematically this 250 should be able to run 140mph, wind loads in the real world limit it's top speed to just a touch over 100mph (land speed record).


    Just went with the Bridgestone TW 301 and 302's to replace my worn out TW 18 and 19. Though they are a touch larger, I compared rim sizes of several bikes I have and these should be a good fit. Will post pics when fitted. Unlike many of you my intent is use the DR200SE as a MT rig and the Bridgestones look to be a good compromise for me for surfaced and dirt road traveling.
