    Thnx for the reply! this was exactly what i was looking for, because i have airmesh from my previcous bike! and also going to "shave" the edges etc. to make it more comfy. cause now it feels like sitting i a bowl.
    Did you keep the old cover though? or did you buy a sheet of seatcover?

    Yeah I kept the cover and it is still dished like a bowl. You could improve it by having a couple buttons with threads through the shell and pull it down in the back but since I was in the middle of the trip I didn't have this option; I have done this in the past on other bikes.

    The trick with dished saddles is not to fight it just slide forward until you are balanced and seat isn't pushing you forward and putting pressure on your wrists. It will feel unnatural at first in feet/knees but it is better than constantly sliding forward and you get used to correcting position on up/downhills.

    Ok, i will keep that in mind. It's not a horrible seat, but it has room for improvement :)

    I am still looking for the updated Oil Strainer Part # M000P03544
    What is my best parts source in the USA?

    From what I understand US bikes already came with improved strainer; they were built after the recall was issued in Australia.

    Your best bet for parts is SWM dealer. If parts haven't changed number since Husky TE-610/630 KTM should have them and many parts identical to Aprilia/Ducati of early 2000s/late 1990s, if you find xref number

    Was hoping for an online source where i can order from a website.

    Is it possible to rank the kilometers or miles covered so far by Superdual owners? Has anyone changed the timing chain at 20,000 km as planned in the scheduled maintenance?

    I have 13.5k miles 22000km and haven't done anything even a valve check. It is hard to start so valves are definitely tight. Bike is in storage since October.

    From what I understand there are no issues with timing chain I will check condition when/if I am able to get to bike before it is confiscated due to situation with pandemic.

    First 12 months of ownership. 19,000 km. Last 6 months 1,000 km due to whats going on. 20,000 km total.

    Parts replaced under warranty.

    Flex oil line from the head replaced as it was leaking from the top hose fitting crimp.

    Water pump replaced due to it leaking.
    https://advrider.com/f/threads/new-thumper-swm-superdual-650.1037250/page-109#post-38762629

    Strainer replaced behind clutch.


    Parts replaced by me.

    Fork seals at 7500 km. SKF seals used. At 20,000 I run a feeler gauge around them for a bit of a clean out. No build up under the wiper seal evident.

    Front sprocket 20,000 km. The standard front sprocket starting to show signs of wear. Had a new sprocket so replaced it.

    Greased the head stem bearings at 19,000 km. Was bored due to not being able to ride bike so thought I'd have a look.
    https://advrider.com/f/threads/new-thumper-swm-superdual-650.1037250/page-123#post-39753547

    Rear subframe lower capscrews. The standard items must be replace by better quality items and the top subframe bolt should be regularly checked also. I cannot stress this enough.

    Things I've found.

    I was told by my dealer the valves only needed checking at 15,000 km. Bike got increasingly hard to start. Found both exhaust valves tight. One was slightly open. Its a wonder it ran. I will check again at 25,000 km if I ever get to ride it again.

    A couple of times the last 1,000 km the bike would not turn over at all when the starter switch was pressed. After extensive checking of the electrics the bike would inexplicably start. I bypassed the clutch and side stand switches hoping this would fix the problem. No such luck. The last time this happened I had time to check the electrics with a DMM. Power was getting to the starter but it would not turn over. By passing the starter relay the bike still would not turn over. Saying all this the earth from the battery had been checked several times. I did finally find a problem that I hope has fixed the problem. The positive terminal bolt out of the starter motor has a locknut under the positive wire. This locknut was loose. Its now tightened up. Touch wood the problem is fixed.

    Coolant leaking from the overflow bottle cap. I chased this problem for along time even replacing the radiator cap twice. Coolant level in the radiators when this happened was at about the top of the core. On doing a Google search I found the original TE630 also had the same problem so I'm no longer going to keep topping the radiator up to the top unless the level is below the core.

    There has been a lot of criticism of the close ratio gearbox. I've got used to it and quite like the ratio's. Loaded up in the hills one only has to play with the top couple of gears to keep it on the boil. Saying that I will never use this bike on single track. I'm to old and broken to man handle the bike around. I have a RS300R for the single track.

    Standard pannier racks must be drilled out at the lowest points as water can enter the tubing and they will rust out. Water can enter into the tubes as shown here in the top picture.
    https://advrider.com/f/threads/new-thumper-swm-superdual-650.1037250/page-80#post-37852752

    The bike runs best on 98 fuel.

    A one tooth larger front sprocket was tried. The standard case saver would not fit with this sprocket on. The bike lost its pep when loaded up in the hills so the standard sprocket was put back on.

    Fuel gauge is not accurate but you know after awhile what level showing is what is in the tank. Last bar flashing for low fuel warning does not work.


    Mods carried out.
    I'm just over 5'11''. On test riding this bike I did not particularly like the riding position as my knees did not fit in the fuel tank cutouts and you were basically stuck in the one seating position due to the cutout in the seat.

    First mod was lowering the footpegs about 20mm. This made a big difference to my knees fitting in the tank cutouts. Brake lever was lowered by removing the pushrod locknut from the master cylinder and shortening the pushrod to suit. I tried bending the gear lever down but this was impossible. I dont know what grade of aluminium it is but it is super strong. It is stuck in its standard position. Its not to bad. Better than the brake pedal was in its standard position.

    I have modded the seat several times. Cutting the foam right back past the cut out and installing new softer foam has made a huge difference. I had the bike delivered with the bar mounts turned 180 degrees to give more cockpit space. With the modded seat the handlebar mounts are now in the standard position.
    Most of my long distance rides I use a small Airhawk with not a lot of air in it.

    Head lights are crap. Replacing the headlight globe with a high end H4 globe made little difference. I fitted some driving lights which made a vast difference. My hobby for years has been custom flashlight manufacturing. I decided to make my own driving lights. These lights are are not to bad and happy with the output now. The standard daytime lights have been set up to help the spread on low beam. Both high and low beam are now more than acceptable.
    The driving lights, low beam and hi beam all run from their own relays. Driving lights are switched with hi beam but also have their own switch so they can be turned off all together.

    I made a custom rear carrier with tool storage mounted underneath. The tool tubes shown here have since been replaced by larger diameter ones.

    Oxford heat grips installed running from the aux circuit. This will be rewired in the future to run from their own relay.
    https://advrider.com/f/threads/new-thumper-swm-superdual-650.1037250/page-77#post-37576926

    Aux cigarette lighter socket installed with a USB adaptor to run a GPS. This is also powered from the std aux circuit.

    Volt meter fitted.

    As mentioned clutch and side stand switches bypassed.

    Charcoal canister removed.

    Aftermarket mufflers fitted by dealer along with remap. I had to make a heat shield up and fit it to the exhaust above the right hand pillion peg to stop burning my pants. This is a fault of the aftermarket Barrett mufflers fitted.
    https://advrider.com/f/threads/new-thumper-swm-superdual-650.1037250/page-111#post-38852299

    I did not like the standard wind screen at all. I've made a couple of different extensions. The latest is not perfect but better than anything else I've tried.

    Added a rail to the top of the standard pannier brackets so soft saddlebags can be individually mounted.
    https://advrider.com/f/threads/new-thumper-swm-superdual-650.1037250/page-77#post-37556547

    A stay was made up with the main piece being a rubber tube to fit between the number plate bracket and pannier frame cross tube to stop the number plate bracket from vibrating.
    https://advrider.com/f/threads/new-thumper-swm-superdual-650.1037250/page-116#post-39201414

    Bark Busters fitted with Storm guards.
    https://advrider.com/f/threads/new-thumper-swm-superdual-650.1037250/page-79#post-37715585

    Link grease nipple. Straight one replaced with an elbow so it can be greased without removing the exhaust.
    https://advrider.com/f/threads/new-thumper-swm-superdual-650.1037250/page-78#post-37608569

    Joiners installed in the two hoses at the front of the fuel tank for ease of fuel tank removal.


    Mods planned or would like to do.

    I would love to do the 2 into one muffler. Just cant justify the price of the adaptor.

    Heavy duty earths from the battery to frame.

    New relay and wiring run for compact relay setup for accessorises and lights.

    I love the bike and feel there is nothing better on the market that would suit my needs.

    Next trip which should have been well and truly finished is to Birdsville.

    Feel free to ask any questions and I will try and give a correct answer

    What an awesome post! This is my first time on this message board, but I've been reading a lot of your comments @mrsdnf they're very helpful! I'm seriously considering the bike but I'm a little hesitant due to my 33" inseam fitting well on the bike. I know some of you have made brackets extending the foot pegs which seems like the best solution.

    However I don't have the tools or mechanical know-how to create something like that. I was thinking about potentially using some aftermarket TE630 pegs as a fix. Any advice?

    Think i'll have to drop my bike off at yours mrsdnf, get a few more mods done!

    I racked up 9000km in the first 7 months of ownership and only about 300km in the last 5 months, I purchased my bike around this time last year.

    Mods:
    Comfort seat
    Bark busters
    +3 rear sprocket
    USB charger & volt meter
    E07 Rear + TCK80 Front

    Issues:
    RH forkseal has let got a number of times and I've just noticed is leaking again.
    Well reported sub-frame failure
    Snapped rear stop switch
    Rear Caliper sticking (under repair)

    I've ridden the bike fairly hard in some instances, including some tracks with whoops and washouts. It's handled it pretty well and is usually let down by its rider more than it's ability.

    I'm 6'1 and have trouble getting my legs in tight while wearing my MX boots.

    Also worth noting I'm on a reduced LAMS powered machine so I have held off installing aftermarket pipework.

    JC.

    If I go riding with you Creechure I'll take the 300.
    Are they replacing the fork seals with the stock seals or using SKF?

    I'd say it will be a tight squeeze leg wise. The trick to fitting your legs into the fuel tank cutouts is to get rid of the hump in the seat so you can move back further on the bike as well as lowering the footpegs.
    There is another mod I read about where the boss was cut from the bottom of the footpeg pivot and then placed back on top. Cant find a link at this point in time.

    Yup, put the boss on top then swap the springs to the other side footpeg. No welding required.
