maggdog Posted November 9, 2016 Report Share Posted November 9, 2016 If you ride your banshee about 30 minutes or 10 minutes, after warm up, and start to sputtering when you hit wide open throttle Can be many factors this help me http://www.bansheehq.com/forums/index.php?/topic/164219-explanation-of-chassis-and-engine-grounding/page-3#entry1819019 http://www.bansheehq.com/forums/index.php?/topic/172766-best-way-to-ground-motor-to-chassis/ Those topics has some pics that can help to chose a way to ground the engine to chassis This fix the problem of my banshee when sputtering when is warm up I think the problem is cuz when the stator and screw are hot can lose the contact and don't work well Note: this is a option that can fix the problem, but remeber all banshees are differents, if this don't fix yours, keep in mind other things like a coil, stator, overheating, compression, air leaks, jetting, spark plugs, plugs, quality of cables Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted November 9, 2016 Report Share Posted November 9, 2016 It's a topic of back and forth. I know j-Madd will come in here and dismiss the ground notion. And with results to back him up. He's got proven runners and no grounds. But I see it as this, it won't hurt at all. Most any bike I work on gets one. Dielectric grease and sanded contacts. Electrical can be strange and frustrating. So I'm a supporter on the engine to chassis ground Quote Link to comment Share on other sites More sharing options...

So I'm a supporter on the engine to chassis ground I concede that it doesn't hurt to try a ground strap if it helps troubleshoot a problem. You're right in that it's easy and simple and lots of folks do it. I don't deem it necessary, but I won't continue to argue against it.

blowit Posted November 22, 2016 Report Share Posted November 22, 2016 I will try not to apply "deep thought" on this but possibly offer something to consider. The key word here is "potential". I think I remember trying to explain this before but basically the word potential describes what you would see on a multimeter when testing voltage. When two leads are connected or connected to a common buss, they would have "zero potential" in reference to each other. I suspect the reason Madd does not run into issues is because he does not run a lighting coil? On the factory Banshee, one side of the lighting coil is grounded to the engine AND chasses, and that should hold the same (zero) potential through the entire bike. If something does not stay connected well, you can end up with potential or stray voltage on the black wire. This will either piss off the CDI and it won't fire or put noise on the line that will damp the peak voltage amplitude to the ignition coil. I should note that you do NOT need a big, massive 4/0 cable for a ground. There is next to no power going through it. Technically speaking, 18ga wire would do it but I recommend bigger only for reliability purposes. 10ga stranded wire is just fine.
