The Yamaha Road Star Warrior Forum

I have an '04 Warrior with SS pipes, Churchs' v-bak, and pcIII . Last week I added the Dynacoils for good measure understanding that they delivered no more hp, just consistent, reliable fire. All I can say is WOW...my bike has NEVER ran like this. I was moderately impressed after adding the v-bak, then I had  a friend here on the forum send me an AMAZING map that made a huge diff from the pc III suggested map for my mods. However, I still had dead spots and inconsistent throttle response through out the range of throttle position and rpms.I just assumed that the last bike I owned being a suped up crotch rocket that maybe I was just expecting too much out of a cruiser.So last week I added the coils just for good measure and a prospectful gas mpg gain. After my first ride with the new coils i felt like I had a new bike! The dead spots are gone and I have consistent STRONG throttle response throughout the gears. I dare say that my old crotch rocket would be hard pressed to keep up with me now! I highly suggest this mod for those feeling like they just can't find the map with a  sweet spot that makes their bike strong in all gears. The problem could be in your coils. Don't forget to change the gap ! It is money well spent ( about 150.00 with new wires and coils from Phats ).

PS here is the post i used for a guide: http://rswarrior.com/forums/AddPost.aspx?ForumID=15

Soooo...    which coils did you get, there's 3 on DynaTek site. DC1-2 or DC4-1 (these both have 2 outputs ie: 2 plugs).  Also, is it possible to get the map so I can try it?  Just pm me.

Thanks 

Bob

 Jason, your link refers to adding a post to a thread, not a guide to installing coils! Can you revise it?

Sorry about the lack of info! The coils are Dyna DC2-1 and I used Dyna 8mm suppression wires. Here is the CORRECT link : http://rswarrior.com/forums/p/27284/390371.aspx#390371

Sorry for my haste. I was just really stoked!

 Good job, thanks for the correction. I might do this mod over the winter.

I  had to modify hole pattern and widen rectangles for coils. You may have to turn the cone on your vbak to make it fit also. It is a tight fit, but it will all go in there :)

I have had a few pms on wiring. this is how I wired the coils up.

 Baron Customs has listed for a warrior DC4-1  Dynatek coils. I wonder what the difference is between the DC2-1 and the DC4-1. The DC4-1 is listed for the Road Star also. Just wanted the correct one.

 DC2-1's are 1.5 OHM, DC4-1's are 2.2 OHM.

Yes, use the DC2-1. 

The confusion is the Baron's website shows DC4-1 for the Warrior which appears to be wrong since the Warrior OEM coil Primary Resistance is 1.31 ~ 1.79 Ohms.  I've emailed Barons and Dynatek for an answer.  See answer in post below.

The window of opportunity is this:  Its the Denso OEM coils that are Primary Resistance 1.31 ~ 1.79 Ohms and its still possibe the ignition system is capable of greater numbers.  So rather than assume, I asked. 

To be safe, I removed the Popular Mods link to the DC4-1 on Barons until there is an answer.

The DC2-1 works fantastically by all accounts since 2003.

The DC4-1 doesn't show up in any post I found written by members actually installing.

 Thanks for clearing that up Arizona Warrior, because I was just about to order the wrong ones. Been looking to do this for a good while.

Stick with the DC2-1 for the Warrior as above.

Here is Dynatek's answer, confirming Baron's website presently incorrectly lists the DC4-1 coil.

Hello Mike.
I do not believe we show the Roadstar Warrior on our website, (as we have no ignition system available for it) only the Roadstar. They are 2 different machines.  I have no specifications for the Warrior coils, but if the factory spec is 1.3 to 1.7, the DC2-1 should work fine.  Thank you,

In case helpful, the R* has seen three basic model changes and I don't know which of those the DC4-1 fits but could presume a guess.  The early model was 98ci carburated, the mid-model was 102ci carburated, and the new '08-'09 model is 102ci injected al la R*W motorwise.
