Imho, lithium should be fitted only to bikes that came with such as OEM or if really a must to more modern charging system bikes, post 15' for the sake of argument. @AirCon I am running lithium in my suzuki rgv250(1994) track only bike and although had no issues since 2014(same baterry) I am starting to worry I might end up in a very hot ride Now the question, is it safer if I keep the headlight on? Was thinking it might use more electricity therefore the rectifier won't have to work that hard, or am I miles out here?
You are correct and incorrect, depending on which part of the circuit we are talking about. Borrow a FLIR camera like this..... And have a quick look around the charging components and see what's getting hot and how hot. Then experiment with lights on and Off , try different batteries etc. Anyone want to pop into Heathrow when I'm not busy I can give you a quick check....
I was stressing the resolution of the check, it actually displays to 5 decimal places, so it settles down to 0.00003Vdc .... bit of ambient noise being seen as voltage.
So to summarise. The battery on this bike did not get hot but it did completely fail after being connected but untouched for many months while the bike was stored.
I'd suggest that this battery failed due to excessive charge current, probably caused by excessive charge voltage for the battery type. Battery failure was caused by charge, not discharge.
the question a dealer should be asked is whats different and what extra or different is fitted to the wiring, charging, or regulator system between a 959 corse thing with a lithium battery fitted as an option and a run of the mill 959 without it. ive run the same track bike with the same regulator and charging system with a std yuasa battery, ( that went poop) a glass mat technology small battery, and a lithium ion shorei battery all of which get boosted for start up by a mahoosive car battery.....with no issues over the years..
top tip for the track bike is to disconnect one of the 3 yellow wires out from the generator to regulator...no need for the extra charge ie no lights etc, and there is a horsepower gain!!
yep ...worth around 4-5hp if it helps its not my idea i was advised by a leading motorcycle electronic genius! you dont need the extra capacity on a track bike with no lights heated grips, twat nav and so on..
So if the energy being generated in the stator cannot go anywhere what do you think happens to the temperature of the windings in the stator? Have you had a look at the stator after performing this trick? We are talking about a ducati charging system, not any other bike.
Are you sure he didn't say remove the Stator / rotor rather than just disconnect it? Sensible as it would reduce load and rotating mass, speeding up rev response. I can see that would result in a power gain, but not 4-5HP.... If that was the case, for the sake of the maths then assuming just 50% efficiency that makes the generator set generate over 2kW...... which it doesn't Around 350-500 Watts would be normal, given real world effiencies then less than 1/2 HP gain. I'd suggest that this electronics genius is pooping from his lower arm joints.... or been in the pub a very long time.
id suggest this electronics genius has created more motorbike related electronic trickery than you've had shits!
But in this case he's wrong or more likely you misunderstood him. Are you going to provide any facts to go with your current understanding? I've over 160 designs in production. Had a lot more shits though...
+1 with AC... electricity is still being generated... where’s it going? Heat. Also, the very act of doing so is what’s sapping the tiny bit of power. Only way to stop that is to ditch the entire system and go total loss.
If one wire is disconnected, the circuit for one phase of windings is open and not creating heat/current.
I asked an auto-electrician about using a Lithium ION battery in my 848 and he said that it's a bad idea in those generation of bikes due to the fact they don't have the most stable charge speed and can cause issues. The newer stuff is definitely more suited to Lithium ION applications.
