Yamaha ybr125 high performance ignition coil?

What is a high performance ignition coil? and what does it do? Is it worth it? Would it harm the bike or would i gain any better performance from it?

Did you replace it with a YBR engine?

Oh, I've just remembered! Mine was actually red and orange.

I fitted it because the plug caps on the stock ones were actually claimed to cause problems with arcing and RF interference. Not that I had any basis for believing that the replacement was any better. But... red and orange.

tl;dr version - don't replace it if it ain't broke.

It's mental that you have such a high karma but all you have ever done on my posts is troll.
I may have little to no knowledge on bikes, but i love them and want to learn.

What does it do? I'd guess it creates a higher potential difference between the plug electrodes than a standard unit. What this is supposed to achieve I have no idea. If anything it would slightly advance the ignition which would make performance worse if anything.

In thirty or so years of driving I'm yet to come across any simple plug in miracle performance gadget that actually does anything noticeable,

Oh man OP I remember being you two years ago.

Got my shiny R125 and was like "HOW DO I MAKE IT FASTER".

*Buys ~~faster~~ louder exhaust*

*Searches Google for mysterious red powerband*

*Buys blue rim tapes for +5mph*

Exaggerating a little but it's hilarious to look back on the amount of cringe. I knew fuck all about anything automotive two years ago.

Anyway, after some tough love from BCF I learned.

The best thing to do if you want to ~~survive~~ learn stuff on BCF is to not get salty and allow the banter to flow over you while you absorb the nuggets of info hidden underneath it.

Anyway, for a serious upgrade to your CG you'll need to buy a donkey from an Arabian market trader (they have the best ones) and get it to pull your CG.

It'll add +1 donkeypower, which is around 0.3 horsepower. Big increase for a 125.

One of the reasons they are used is when running compression so high that a spark can't form in the cylinder or using a plug with a bigger gap you can't get a spark at the stock coil voltages.

The super high performance coils generally makes the voltage higher.

So the point I'm making is that you need to add a high flow pod air filter and a high performance coil to really feel the difference. Sometimes with all the added air flow and big sparks your cylinder pressure will be too high so you need to loosen the spark plug by about 2 turns.

HTH Thumbs Up

That seems... reasonable. I did some physics, so my gut instinct is to consider everything to be spherical and in a vacuum.
