    You'll have to give us some more info. Cranks fine but won't start? Cranks slow? Button does nothing? Backfires?

    This a quote from the "Short way around the world"
    http://shortwayround.co.uk/suzuki/

    Wondering if anyone has given this a try?

    Headlight – Not riding at night is one of the golden rules of overland travel by motorcycle and I avoid it most of the time. There have been occasions though where I’ve been caught out and where I would really have benefitted from better lighting. However, as these times are few and far between I didn’t want to spend any money on expensive additional/replacement lights. The solution (though I’ll have to wait to prove it) seems to have come simply and cheaply in the form of a simple relay circuit and a better bulb. The theory: The stock headlight circuit uses small gauge wire connected through the switch to supply the headlight. This modification uses the OEM wiring to switch one of two relays (1 High beam, 1 Low) which in turn connect the headlight direct to the battery via larger gauge wires and an inline fuse. This system reduces the voltage drop to 0.1v; a drop of 1.0v can equate to a 25% reduction in the headlights ‘output. I also added a Phillips X-Treme headlight bulb of the OEM rating 60/55w.

    The problem with manufacturing in China is being able to stay on top of them. They love to start subbing unapproved materials any chance they get to save a few pennies.

    I am pretty religious on maintenance on my bikes, but I also ride the piss out of them :lol3

    The suspension on my F800 was utter garbage. The forks being the worst. Both shock and fork internals were thrown in the trash. Had to spend some bucks to replace them with decent suspenders it should have come with. No chain guide either was a clue to the cost cutting by BMW. I can tell you the DR suspension as low end as it is, is still better then the stock F800. And the top shock mount on the F8 is another eye opener.
    Ill keep the DR myself.
    The GSA is all together different. Better build quality and components then the smaller cousin.
    This is just my opinion though but I have owned them all.

    I had a short in my wire harness, and instead of fixing it I ran this setup and the lights are much brighter.

    Battery could be on the way out. Get it looked at by someone that knows how to test them. Or try a battery from a friends bike. Same thing happened to a mates bike. We went through everything including the stator and stuff connected to that. And it turned out to be the battery had enough power to crank but not enough to fire.

    Sounds like it would be a good place to start. I know on my DR, the high beam indicator puts out more light than the high beam itself. I'd also replace the headlight connector itself to a higher grade unit, as I have seen issues in other Suzuki's that I've owned. More food for thought: http://www.danielsternlighting.com/tech/relays/relays.html

    Try laying the bike on it's side for 10 seconds, pick it up and see if it starts. If so, I suspect it is the float assy o-rings. That was my trouble twice in 7 years of owning mine. (so far)

    Finally got a mid-pipe so I could do the GSXR can mod. Using a x40f1x (Aussie x40f0x) and a mid-pipe made by a bloke over in QLD (AU$175 + shipping - much cheaper for me than the other pre-fabbed options). It's not as smooth of a bend and such as the other options, but considering I haven't done any mods to the intake and probably won't do more than remove the snorkel (yes, the snorkel is still in there atm), it's not going to be an issue :lol3

    Just have a quick prototype/unfinished bracket currently because I was eager to mount it all up and test it out. I need to do some tweaking of fasteners to make sure it's all honky-dory, but from the quick ride I did earlier tonight, it's going great.

    Previously the bike seemed to labour when giving it throttle while cruising, which I had just put down to the BST carb. I need to do some more riding to make sure (:wink:), but I'm pretty sure that is now gone with the new exhaust.

    Anyway, some photos:

    That pipe looks great!! I don't see any problem with it over the expensive pre-fabbed options!!

    yeah all original from me in the past 12 months or so. still learning a lot about movies. the on bike camer is a VIO POV HD, the roadside is mostly a Canon EOS 5D and then there is a couple of shots from some point and shoot cameras (theres been a couple now after a sacrifice had to be made to the gods of soul capturing devices). all the tracks so far in the movie have been pretty easy with a couple of tough sections. the good mud will be in the next installment if i ever get round to finishing it.

    It is likely to either be dirty, have worn out/damaged parts, or was/is just not jetted correctly.

    During the laying the bike on its side procedure, do you turn the petcock off?

    Searching this thread for "clip position" didn't seem to yield anything on the first several pages, so I thought I'd ask.
    I just got the non-USA OEM needle and clip for my carb after having a bent needle from the PO, and I'm not sure what clip position to use. So here's the basic run down of my bike:
    - Lives around 5000 ft above sea level
    - Airbox mod
    - Stock exhaust
    - K&N air filter
    - 12000 miles (for whatever that matters).

    Anyone else running a similar setup that can tell me what clip position and possibly jet size that I should be using? I'm not a tuner in any way, and I don't have access to a professionally setup DR650, so I'm not sure what all I should be looking for.

    The standard clip position is in the 3rd groove.

    Correspondences on CV carbs:

    Low rpm all throttle positions: float height, needle base diameter, emulsion tube outlet size
    WOT operation overall: main jet
    WOT operation between HP peak and red line: main air corrector
    WOT operation below red line: jet needle shape
    1/4 throttle opening: jet needle clip position
    1/8 throttle opening: pilot jet size
    1/16 throttle opening: pilot jet size
    idle: mixture screw adjustment

    Put some tape on the throttle housing and the edge of the grip. Mark zero throttle with a sharpie. This is best done with the engine idling, so you can tell when the slack in the cable has just been taken up. Turn off the engine and mark wide open. Now take a tape measure (metric works best in my opinion) and measure the length of the arc. Put a mark at the mid point. Duplicate this procedure to mark the mid-point between here and zero throttle opening to get 1/4 open. Repeat for 1/8 and 1/16 openings. Don't have an accident trying to look at the marks while riding. If you do, I'm not responsible!

    Tune from the top down, i.e. get the right main jet in it for proper wide open throttle operation, then set the needle clip position for correct operation at 1/4 opening, then install the correct pilot jet for proper operation at 1/16-1/8 opening. Readjust the idle mixture after every jetting change. Without the ability to dyno with 5-gas analysis, I would go progressively leaner until there was just the very beginning of a discernible misbehavior. On the main jet, I would then go 2-3 sizes richer. On the needle clip, I would then adjust 1-2 positions richer. On the pilot jet, I would install 1-2 sizes larger. Please do bear in mind that if you have high compression, poor exhaust flow, low octane fuel, and/or ignition timing that is either correct or overadvanced for the correct mixture, tuning via this method could cause detonation and therefore engine damage.

    Regards,

    Derek
