Stick Coil Conversion

[TJS]

I'm starting the conversion on a Bandit 400. I've done the same conversion on my track bike, 1994 GSXR 750w. I will post more details and video as it goes. You can probably find others here that have done the same thing on your particular bike in the "Search". Below is the Bandit in process and where I originally got the idea and "How to...".

GSXR-W was switched to option 2. I'm having a local guy install a clutch-less shifter this summer. He requested I change over to option 2.

Testing the coils...

I'm no electrickery expert but I think if the sticks are paralleled like opt 2 you'll get 12v but circuit resistance is halved so twice the amps will flow - so stressing the ignition amp transistors. 12v @ 3 ohms = 4A, 12v @ 1.5 ohms = 8A. But parallel gives 12v @ 0.75 ohms = 16A! Please get an adult to check the above.

The local guy's diagram hurt my head, and my neck. 

What issue of PS was that in? I remember reading it. 

Need to read it again as I'm about to set up some as well.

Option 2 will burn your CDI out

As everyone has said, You should run them in Series as you need to load them coils up. Ideally, you will want the resistance to be between 3-5 ohms, If you can't get 3-5 ohms with a pair in series, you'll need to add a high wattage resistor in line. (40-50 watt), you can heat sink it to the frame.

Not enough resistance will give a poor spark, plus other problems.

Upgraded to BUSA coils from SPS.

Bandit and GSXR-W have switched up now.

How much shorter are the busa stick coils compared to K1 K2 1000 types? Or are they the same length?

Same Length

Hi, i am looking for information on how to connect pencil coils to my 97 blade wich run on coil packs, any info that can help wil be appreciated,thanks

Ooooh you're going to get some flak for asking that !

[Joshua]

What do you mean flak? I do suzuki build often, just wondering if it is possible ? Couldnt get it right on my turbo katana, found this thread and thought to ask

1) Remove fuel tank, drain fuel into a Suzuki tank.

2) throw away the 97 blade.

Sell fartblade. Use funds to buy another air or oilcooled Suzuki, then do a stick-coil conversion. Also, please post pics of turbo Katana

[Joshua]

Anyone stil assisst me with a pencil coil conversion? Is it just as easy as that daigram they posted ? Dont want to blow anything #turbokat

[Arttu]

The Kat looks interesting!

The coil conversion principles should be pretty much the same for all 4 cylinder Jap bikes that are originally equipped with double coils. Exact details of some weird H or K or whatever bikes are out of scope of this forum

Main thing to measure is the resistance of the OE coils.

One stick coil needs to show half of whatever reading you get from a stock one.
