Hey 550 guys - DCC coils ?
« on: November 16, 2014, 08:55:51 AM »
I usually play with 750s, but I'm building up a 550 for a buddy of mine.   Sat outside for a very long time, so the plug wires coming off the coils are hard as a frozen rope, loose at the actual coil and cut too short to use.

I had always assumed that the coils for 750s and 550s were the same.  After reading and looking a bit this morning, I've found that they are different part numbers.   Something about the internal windings - over my head.

I've used repop coils from Dime City on my CB750s with good success.   5k coils with 5k plug caps.
These:   http://www.dimecitycycles.com/vintage-cafe-racer-caferacer-bobber-brat-chopper-custom-motorcycle-electronic-ignition-parts-cb750k-12-volt-ignition-coil-38-2019.html

To me it seems like the 550 likes 5 ohm coils with 5 ohm plug caps -  Caps: VB05F & XB05F
Any of you 550 guys running those on your 550 ?   If not, what are you using ?

Yep, I'm the kid that figured out how to put things back together...eventually.

Apperantly 3 ohm coils over tax the charging system on 550's so 5 ohm for me.
I'm using Dyna coils and they work great.

If you want to upgrade the entire system I've got Section Bobbin coils and a sweet optical ignition that works awesome on 550 engines.
The coils are rated at 120,000 volts which is about 4 times the rating of a standard coil.
PM me if you want. I'm not trying to spam you, just offer an option.
