For the benefit of all... here's one way to remove the exhaust / muffler from a DL650X or a Wee with the OEM Suzuki belly pan fitted.
Dan Davis gives an excellent account on how to remove the exhaust on a non belly pan bike here
http://www.ddavis.co.uk/Daniels_website ... m_650.html but for those with the OEM skid plate / engine guard or whatever else it is you want to call it there's a problem. The support bracket for this runs under the exhaust and is fixed to the bike using the lower engine mount bolt. There was no clearance at all on mine (the exhaust in fact rubbed against it) so there is no way you can lower the exhaust from the bike with this still on. You have an added problem that the side stand is fixed to this support bracket and you can't get the exhaust off when the bike is on its centre stand
I think you also need a special tool to get the right hand side undone as well though I may be wrong - either way it looks a real pain in the backside and you temporarily lose your side stand. In fairness I don't imagine Suzuki's designers were wildly concerned with how easy this would be (or changing the valve clearances, sorting the screen to reduce buffeting, etc etc!
).
I found a way that worked for me though. Follow Dan's website up to the point you're ready to lower the exhaust off the bike (and leave a bolt in at the back end of the exhaust just for some support).
1) Undo both rider footpegs - they'll hang gently where they are by virtue of gear change linkage and rear brake, that's fine.
2) Use a 14mm socket (and a *proper* hex one - this bolt is on bloody tight and if you use a "star" one you'll probably round it off) and undo the bottom engine mount nut on the right hand side of the bike.
3) Slide the engine mount bolt out from the left side of the bike. It should come out very easily given you've removed the obstacle of the footpegs/attached detritus.
4) The metal bracket is now free on the right hand/exhaust side, still very firmly affixed on the left - however it is flexible enough that you can bend it down a few inches without any harm.
5) Get the bike on its side stand. Lose that rear exhaust bolt you had in for safety's sake. Press down on the centre stand with what bit of body you have available and you should now have just enough room to lower the exhaust off the rear link pipe.
6) Marvel at how heavy it is
Leave the engine support bolt out and bracket bent down as you'll need it that way to refit the OEM exhaust and it'll likely help for fitting any aftermarket one also. Once the exhaust is back on simply reverse the above steps.
Voila!
Hope that helps someone in the same situation...
