    Cheers!

    Digital and you loose access to other info have to switch between modes

    The dash is very much the same as on TE they added some minor functions.

    After speaking to some people i decided to have ago at removing the left hand silencer (viewed sitting on the bike) and blank off the pipe in preparation for fitting a derestrictive silencer with arrow map o2 delete. I'm looking to loose weight and have the option of fitting a rotopack.

    The total cost of the parts was $33 aus

    Sourced parts were

    (1) metal post cap 42mm inner diameter (Bunnings Australia) $5

    (2) Silencer gasket from a Suzuki 39mm inner dia (part no in photo) $23.

    (3)M8 x 50mm stainless steel bolt and nut (Bunnings) $5

    I used a dremel to cut 4 slots in the cap to allow the retaining clamp to clamp the cap down onto the exhaust pipe. This proved a failure as the clamp couldn't compress the cap due to the thickness and the first test run blew the cap off at 60kmh.

    The silencer gasket is an interference fit on the remaining pipe so I chamfered one end (dremel) to get it started on the exhaust pipe.

    The bolt on the clamp from the exhaust was too short and wouldn't compress far enough and this was replaced with a bolt and nut.

    The first test run was a failure as the cap got blew off this was due to the cap being too strong for the clamp to compress. I subsequently cut approx 12 slots in the cap to weaken it enough to be secured properly.

    A short test run later the cap is still on.

    The bike used to idle between 1750-1800 rpm it now idles at 1750-1900rpm. Some hesitation at 2500rpm and after that it revs well.

    Total weight saved so far 5.5kg and it is totally reversable. Exhaust cap front fitted.jpg Exhaust cap with gasket.jpg Exhaust removed.jpg Exhaust suzuki gasket.jpg

    Still to do, a free flowing end can and arrow map with os delete.

    The can weighed 3.5kg. Total weight with the mid pipe, heat shield and can was 5.5kg. Once i replace the other can with an open can it should be around 8kg in total weight removed.

    Thanks! I'm looking at pair of cheapo chinese akros to replace stocks; they are <3lbs ea.. have you looked at getting 2-1 Y pipe welded instead of capping one pipe?

    I am in the process of getting a quote for a Y piece which is the two 38mm pipes into a 51mm pipe which suits most end cans. I want to be able to go back to the original set up if needed.

    I got the latest superdual map with arrow exhaust loaded into the ecu yesterday and it has helped smooth out the running and I would say gives the bike a bit more get up and go. I have also ordered a cheap chinese akro but that will take a few weeks to arrive. My concern currently is that the remaining standard pipe is getting very hot due to it flowing double the exhaust gas and this should be fixed with the new end can.

    IIRC they're 40 and 44? mm and Chinese ackro 2" and comes universal 1.5"-2" (38-51mm) adapter.

    If you can get Y-pipe well made and reasonably priced you can probably sell quite a few on Amazon or eBay.

    Yes, we have a few guys interested in the Y pipe. Now that the Usa has the bike there maybe more people interested or someone will make one there.

    And hopefully a decent range of aftermarket accessories for the SD!
    Would be very interested in a fully-reversible Y joiner.
    For a wishlist, I'll add better instrumentation, better seat and bigger tank...

    Yes the Superdual is sadly lacking in accessories although this maybe because it already comes with the extras.
    It's more likely due to the number of bikes that have been sold which is small compared to something like a Dr650

    I'm sure someone will make a Y piece as it will free up one side and greatly reduce the weight. I would think that it's at least a 6kg saving.

    For a better seat the guys in the Usa should send the seat to seat concepts as they are only waiting for a seat pan. The rs650r already has been done as someone sent their seat pan from Australia.
    The tank range is already pretty good with a claimed 400-450kl fuel range.

    350+ks is more realistic.

    More like 300 - 350km range.
    The tank does not hold 18l.
    And the standard fuel gauge is unreliable.

    Thanks guys! Haven't found what they recommend for US or if they tuned differently for our market.. probably not. Factory MOM says 95 which is our 89 by (R+M)/2?. Makes me wonder how it will cope with A-80 which was an only option in some places in central asia few years back. 2 more days before I fly to pickup bike.
