I would like to replace the coils on my 900 seca anyone know where to get new ones? My local dealer isn't so local and they don't seem to want to be bothered with anything this old

Chacal has some.

Get the Dyna ones HCP245 for $119.00 for 2

and the leads and caps for $18.00.

When mine go that's what I am getting:D.

I'm having the Same Problem with my 900. Coils. Or so I thought!
Actually, the problem was the wires.

Since the wires are part of the Coil ... you naturally suspect that replacing the whole Coil is necessary.
Not so.

You can do some light surgery to the Coil and replace the wires with new high-performance wiring.
(Just go to a junk yard and rip yourself a couple off a BMW or Audi).

I have a decent spark coming through, so I probably could get away with just replacing the wires... how light of surgery is it? before I go tearing into the coils....

I also offer some spark plug wire SPLICERS that allow you to easily remove most of the plug wire from the original coils and replace them with new wire:

Spark Plug Wire Splicer:

pw1) Aftermarket NGK-brand SPARK PLUG WIRE SPLICER. This handy little device allows you to cut off a bad original plug wire and splice in a replacement piece, which is really handy, since the plug wires on the original factory coils are basically non-replacable......so if a plug wire goes bad, the whole coil is basically junk! Not real clever factory engineering, but there you have it.

This splicer allows you to extend or replace a damaged or bad plug wire, just like you would splice into a piece of electrical wire. Watertight, screw-on design is made from a high-impact plastic material and adds no resistance (0 ohms) to the circuit. Very handy and practical solution!

HCP2789 In-Line Plug Wire Splice, fits up to 8mm plug wire. Each:
$ 6.00

HCP2789SET4 In-Line Plug Wire Splice, fits up to 8mm plug wire, set of 4:
$ 20.00

Not all that bad of a job.
Can be messy with plastic shavings all over the place.

Last time I did it, I used my ShopVac hose kept close to the Dremel cutting bit and just vacuumed-up the flying plastic.
Got most of it.

You grind-away the Coil Case on a straight line following the Wire.
Eventually, you see the wire.
Use the bit and expose the wire.
Cut it back to where the wire ends.
Then, relieve the space surrounding the wire.
Once enough of the wire is exposed ... you can twist the wire and break it loose.
The wire pulls-off a pin that looks like a nail head which is the High Power Supply.
Wipe down the new wire with some ArmorAll and it will be easily pushed-in through the undisturbed opening at the front of the Case.

I stripped the wire and soldered the connection.
Stock is just a Press-on fit.

I filled the cavity with 5-Minute Epoxy after the connection was made.
A little Dremel Sanding Disc to shape the cured Epoxy.
A little hand sanding-down.
Rattle can touch-up and your are good-to-go!

^^^^This is all provided the primary windings check out good. If one of them is burned out, the coil is junk. Be advised, in the 5 sets I have tested only one of them had this condition, the rest had high resistance readings on the secondary lines. For $12 in spark plug wire, I fixed 4 1/2 sets of coils in the manner Rick described. Good luck and test those coils before you condem or repair them.

I may have to do this with at least one of my coils eventually, any chances someone can provide some pictures next time you end up doing this procedure? I'm a visual person, so reading the description just isn't as helpful as seeing a picture. Thanks!

Check out Rick's post, he has some good photos and you can find more in our How-To/Self-Help link section.

After 15 minutes of searching I still can't find pics of this procedure anywhere, they're not in Ricks gallery, and I can't find any how to's for this topic. Can someone provide me a link to where this coil procedure is documented with pictures please?

I'll try to put-up another picture this evening.
I have to wait 'til the car gets home and get my camera out of the trunk.

Look under the links section, DITY thread, bottom of the page.

Great, found the right section now, thanks! My bike has been running ok, but occasionally it seems like the #1 cylinder isn't firing as the exhaust doesn't warm up on that pipe, the shop I took it to a while ago said that they thought the coil for 1 and 3 was possibly going bad. I'm guessing it's just a small break in the wire that can be fixed with new wires. Now I'll be able to test and repair it myself. Nice writeup, and thanks for pointing me in the right direction.
