    Last second work - before the 4th of July weekend

    My 03 SV1000s has suddenly developed an unnerving problem - it cuts out/dies occasionally under medium to heavy throttle, 4-6000 RPM. The bike goes dead - gauge cluster is blank etc. for a split second, then it "magically" restarts itself. This sometimes happens so fast that I'm still on the throttle and get a blast of power when the bike restarts. Not safe if that happens in a tight twistie, obviously. I'm also feeling a little hesitation between 4-5000 RPM. I had a similar issue with my previous car, and new plugs & wires solved the problem, so I'm *really* hoping it's worn out spark plugs and not a bigger FI problem.

    Any ideas for shops or mechanics that might be able to get me in on short notice? I had a big ride planned out for this weekend and would hate to be stuck at home! I would do it myself, but have never changed spark plugs, and have a spot in a parking ramp instead of a real garage to work in.

    One other note - I had this issue last weekend in RMNP at 12,000', figured it was bad gas or altitude related. Fresh tank of 91 octane non-ethanol gas and 5,280' Denver riding... same problem!

    As simple as it sounds make sure your battery connection is tight. For local shops check with Tfog, Mad Moto, Quick Cycles..

    I don't seem to have any charging issues though - battery is brand new this season, starts right up every time.

    I had MadMoto on my list to call... they aren't open until 10AM. Thanks for the other two suggestions, they didn't pop up on google search.
    I will certainly check my battery connection before I take the bike in - hadn't thought of that, thanks! I put a new battery in this spring and it's entirely possible that a screw has worked its way loose.

    Google or research on the SV forums the green plug of death, I'll almost guarantee that's your problem. On the SV there is an ignition wire that runs through a green plug that's buried underneath the front of the gas tank. On the S models, there isn't enough airflow to the front of the bike, and that circuit has too much amperage for the gauge of wire, and it melts that plug.

    It causes intermittent shut downs, exactly what you're describing, and it's caused more than a few SV's to fall over.

    I never experienced it on my SV, but the plug did have some blackening from heat. I cut the wire on both ends of the plug, and soldered it directly back to itself, bypassing the plug/connector.

    I read through that thread- my bike hasn't gone completely dead like some people described, but there was one guy who was having similar problems (bike cutting out momentarily while running). Thanks for the heads-up! Looks like I will be buying a soldering iron today.

    Tip over switch. I had an '03 1000S, and I had to fill it with silicon. Under hard acceleration it would cut the motor. I think I had to cycle the kill switch or the ignition to start it again but it was a while ago and my memory is a bit foggy on that.

    I gave this a shot - it was indeed the problem! My knuckles were bleeding and there was much swearing involved, but I rode 900 mi this weekend to New Mexico and back after the "green plug of death" fix. Thanks a million to Aaron for the suggestion, saved me hundreds in shop bills. It's crazy how one seemingly unimportant little wire can kill the whole bike.

    You're welcome, I'm glad it fixed it and you were able to save a bunch of money!

    He even helped me do it a few years back as we were in there playing around with desnorkling and the TRE (Timing Retard Eliminator), better to be proactive about some things as the consequences of bike shutdown in certain situations can be fatal.

    That's another thing you need to order jsprech, is a TRE. Search those SV portal forums, it won't be hard to find. It is simply astonishing how much smoother the bike will run after a $15 retard eliminator is added.
