Posted: 12:26 - 21 Sep 2017 Post subject: My current findings on ignition coils |
|
|
This is information for people that actually work on their own bikes. If you own a bike but have never touched a spanner in your life then shame on you, and go sit in the corner and think about what you've done. And if you're one of those pathetic oiks that religiously only uses OEM stuff then go sit in the corner there with Dumb-ass until I tell you otherwise.
Long ago I discovered that a big old oil filled car coil like a Lucas or Bosch was the best coil for my bikes with points ignition. I tried all kinds of "motorcycle" coils and nothing came close so that's what I used.
All my other bikes with electronic ignition generally kept whatever coils were on them if they didn't fail, and if they did fail they usually got car coils adapted onto them. I have never had one of those big old oil filled car coils go bad, ever.

Lately I've been experimenting with some different coils on the electronic ignition engine I've got now which uses a dedicated coil or two off the alternator to run the CDI box in AC mode as I've currently got it wired.
Although it's early days I seem to find that running two separate coils in series works best. They don't get hot and the alternator windings don't seem stressed at all.
I've found these older types for points ignition are pretty good even on electronic ignition but are a bit big and hard to put away somewhere. They also make twin lead versions which I haven't used yet but don't see any reason why they shouldn't work just as well and I may even end up going with the twin lead version for my current engine:

These type of coils are generically readily available and widely used but I find them a bit expensive and not really a great spark usually. Also the leads are permanently built in so you can't change them, which is a big let down for me. The twin lead Yamaha Banshee 350 coil I have which looks identical to this was the weakest spark of the lot:

A pair of actual Honda coils like this (although I suspect they're Chinese made regardless of what Honda says) perform pretty good and are identical in every way to much cheaper Chinese coils. Unfortunately the leads are fixed and I don't like that. I like to have the option of replacing the leads.

These type of generic coils are found on a lot of things and they are also pretty good. The leads can be unscrewed:

But at the moment the best spark I'm getting apart from the old car coils is from a pair of Chinese GY6 coils for small bikes, and they cost about £6 each. You can unscrew the leads from them and replace or modify as you wish. They are tiny little things, easy to fit away somewhere and readily available:

This is not a long term test (yet) but I see no reason why the cheap and cheerful Chinese coils won't work perfectly fine for as long as the extortionately expensive OEM ones do. Personally I've had absolutely no trouble whatsoever using Chinese electronics for things like power amps and they far outperform more expensive amps from other suppliers. I rather suspect most electronics are of Chinese origin these days anyway regardless of whose name they put on the label. |

So what sort of coil works best on a diesel bike?
And shouldn't this thread be about voltage findings, not current findings?
I can't believe I've just read a thread where someone extols the virtues of Lucas (Prince of Darkness) electrics. |

Old Thread Alert!
The last post was made 6 years, 214 days ago. Instead of replying here, would creating a new thread be more useful? |
