    i wanna get a plated KTM 200 to do a local DS hooligan ride.... did you have to do anything special to the jetting to get it to run 60mph on the street?....

    I bought the bike used and it is perfect as far as the jetting goes... I haven't opened the carb yet to see exactly what jetting that is. hahahaa

    It works, I know that much! That bike has such great throttle response.. I love it.. I have a new chain should arrive tomorrow, going on a nice ride on Saturday. Will probably put another 100 miles on her..

    A picture from last weekend - at the top of a cliff overlooking the highway. A nice spot to take a break and get in touch with nature ;) This spot is my home-trails about 4 miles from my driveway :D

    I bought this to do some dirt-roading with my GF on her dual sport. I planned to register it as an F8. Put the project on hold when I realized how irritated she'd be from having to breathe in the smoke...

    Plaiting a two stroke is the only way to go. Simplicity and reliablity= more riding time

    Don't know if these are the same everywhere, but in the US they were 4-strokes with overheating issues. Local dealer has 3 in storage, has all but given up on getting them to work right. When they first arrived in his shop I was kinda looking into getting one to be my first moto in over 2 decades.

    "...mine is a poor cousin, but it's plated!"

    That's a beauty! I still want to resto mine and plate it, even if the process if a bit iffy. Although the 350 (mine has the bigger barrel) is plenty, I'm playing with the idea of a 500 or 750 triple, just for shock value (;

    Yup, like I said, as long as your gearing is correct for what you are going to be doing, and you spend the time on your jetting, it is an amazing ride. Mine is so smooth, no vibes at all, and I love cruising with the KLR's on the highway. They keep looking down at their bikes cause they are hearing the 2T sounds and they think there is something wrong with their bike :D

    I've done about 20 miles of pavement on my 200EXC at a time.
    At about 50 mph. Wasn't bad, mine tops out at about 65 mph.

    I have the LC4 for rides with more pavement, but the EXC is fun.

    Fuel range is shit tho, even with a bigger tank.
    Think if I tried 100 miles on it I'd be pushing or calling a ride.

    I loves me some two stroke bikes. Unfortunately, I don't see how I can keep my KDX. Nowhere to ride here in Texas, no public land. For awhile several of us were leasing some land.

    I thought of dual sporting it but it would be screaming its head off all to just do gravel and dirt roads in the area.

    So, got me a WR and love it but it will never have the feel of a two stroke. :cry

    In one weekend I put 600 km's on my bike, a mix of everything from highway droning to single track riding, all in 34 degree celsius heat. Most of those pics that I posted above were from that trip. No issues at all. For the highway drones, I would just stop in the shade behind the fuel station and take off my 12 tooth front and put on my 14 tooth front, which takes me all of 5 minutes. Et Volia, I am crusing at 100 km/hr at just under the pipe. Want to pass, just twist the right hand and blow by anything you want. :clap

    On the rear I am running a 41, and for 95% of my riding I am using a 13T on the front. Like I said, if I am going on a long trip somewhere I carry a 12T and 14T with me, plus a couple extra countershaft circlips as those things tend to jump free :) I am jetted a hair fat due to the fact that this engine leans out the hotter it gets, but nowhere fat enough to cause issues. These engines are so deep that on most of my rides I am not even close to the pipe, just rolling in 2nd or 3rd. I hit the pipe just because I love the sound but the corners come up WAY too fast!!! Then once I get back on the road, roll it up and there is no issues at all hanging at the flow of traffic.

    Since I did this build, I have put around 3000 km's on the KTM engine in one year. My buddy that rides a KTM 300 just did a piston swap at 300+ hrs, an approximated 10,000 km's of dual sport riding. When we pulled off the jug, we were wondering why we were replacing the piston, it was in perfect shape.

    Like I have said in the past, gear it for what you want to do and spend the time on your jetting, and there is no reason that you can't dual sport a two stroke. Of course it is going to be buzzy on the road if you keep the stock dirt gearing, if you are just connecting trails and want that dirt pull, then live with the vibes. If you are like me and are doing more longer dual sport rides, then gear it for such. If I am going for a ride, it is never under 100 km's, usually around the 150-200 mark. The luxury of living in Northern Canada.

    Plus nothing can replace the looks you get when you kick over a 2T when you are sitting at a hoity toity golf course ;)

    You guys are my heros!

    I wanted a 2 stroke commuter supermoto like nothing else, but ended having an XR650L cross my path at an insane deal and couldn't pass it up.

    For you guys putting serious miles on your 2 strokes, how is it for riding long distances or commuter miles? Replacing the piddly amount of transmission oil every weekend, or halfway to your destination? Find getting gas at a gas station a pain since you need to add oil? How does the motor handle slab riding, any burnt pistons from an hour of highway riding? If its not to bad I might just look at trading my XRL for a big bore KTM or similar.

    There is something super appealing about walking out of work and kicking over my 2 stroke in the string of Harleys while wearing a suit and tie.

    my 2 stroke dual sport is old, air-cooled, a little temperamental and basically a low-buck beater. that being said, for me it's a great bike for the road around town & finding "urban enduro" areas (abandoned commercial lots, for the most part).
    the furthest i've taken it so far is a ~120 mile round trip in one day. it was fine, but i'm using trials tires... the front tracks the grooves on the freeway. it's geared up to cruise at 60mph under the pipe (so not on it), gets pretty decent mileage, doesn't vibrate too much.
    I'd happily take it further, but really don't have the free time to do so (4 kids, 3 of 'em little).

    i carry premix with me, in a graduated bottle... pre-marked in 1/4 gallon increments, at my ratio (40:1). put 2 gallons of gas in? pour in the right amount of oil, put the gas cap on, rock the bike back/forth, side/side a few times and i'm off.

    it's jetted just a touch rich... keeps it safe. jetting & gearing make or break a 2 stroke when it comes to distance and/or steady speeds.


    funny thing is, i'm now looking for an XR600L... maybe 650L... i like them too much. i'll keep the 2 stroke, too.

    as far as kick starting it in a row of harleys... i kick all my my bikes (even my harley) in a row of harleys (though i don't own a suit)

    I have a 97 RMX 250 that I am rebuilding and fully plan on plating it for Dual Sport trips around here in Idaho. Thankfully, blinkers aren't required here. One less thing.

    I love this bike. Have ridden the piss out of it and am love just how cheap it is to rebuild the whole bike.

    Thanks!!

    For long distance, this thing has WAY less buffetting then my DR 650 or GS 1150 had. At the end of an hr on the GS I wanted to tear off my helmet. It felt like I was being slapped on each side of my head. I really did not like that bike.

    For tanny oil, I do not know what you are talking about. Mine has a small leak on the countershaft seal and I just keep putting in a ml here and there. No issues at all with swaping out the oil. If I want to do it, it is all of 3 minutes. No oil filters and screens to deal with.

    Commuter miles - I commute on mine daily. No issues at all, if you don't mind your backpack smelling like H1R :D

    Gas at the gas station, I use a clear shampoo bottle that I got off a friend who has a shampoo company, marked in 20 ml intervals. 20 ml per litre, pretty simple math at the pump. Turn off the petcock, fill up with gas, pour in the oil, shaky shaky with the bike. Fire up and rip away. Don't forget to turn on the fuel though. Hard to look cool when you run out of gas......

    Burnt pistions from an hr of riding?????? Internet lore. Vary your throttle, don't sit right high on the pipe, and you will be fine. The only thing that I ever heard that made any sense was that if you kept it at the same RPM for the whole hr, that the rings on the exhaust side tend to stick. That makes sense to me, but the riding around here is never a slab drone like that. Plus it gives you a reason to pass.

    Yes, you have to pay more attention to it then a DR, but like you said, when I wheel in to grab a coffee, I always go to the local hippy hangout. Kill the bike, have my java, get on my bike, stand on the pegs, roll out the kickstarter, crank it over as she fires on the first kick (always), rev it a bit just because I can, smell the smell, look at the faces, then hammer away on the gears as I fly down the road. I love the look on peoples faces when I fire it up in public places.

    And on a side note, I tried to blow this bike up this year. I could not. It is very strong.

    BRRRAAAPPPPPPPP!!!!!!

    Here is video proof :)

    Took my EXC out for a bit today, about 30-35 miles.
    Ended up doing some pavement as I ran by a friend's house for a while.

    About 50 mph on the 2 lane, no problem.
    I mix my gas just a little rich, as I think a little more oil is much better than not enough .

    not to hijack ... but as a long time 2 smoker and long distance $ even across australia on a DT400 & raced rds/ TZ . had a plated NSR 400 ...
    Be careful about the "extra oil being good" thing.
    Oils burn hotter than gas. ... good 2/ oil at the correct ratio and good carb set up is better than more oil ever was.

    More oil will lean out the air/fuel ratio without a rejet.
