2002 srx dts

Ran my 02 SRX around the yard for the first time this past weekend, noticed the DCS light was not flashing at start up! it does not do anything, I checked the plug in connection and it is plugged in. Could this be just a burndt out bulb? or maybe even a fuse? what exactly does the light do when you first start it? I just bought this sled and maybe the guy before me pulled the bulb out because it does have an MBRP can on it, and I have heard that this will make the light stay on all the time. Any thoughts?
Thanks for any input in advance.... ;)!

It could be just a burned out bulb.

or..

As the sled is new to you ...has someone changed the CDI box to a 2001 CDI[no DCS]?

You can check which CDI box it has fairly easily:[it is located just above the left footwell under the black vented cover]

-remove screw on left side belly pan that holds the knob for the hood hold down strap
-remove the left side lower screw that holds the black vented side cover to the tank
-carefully lift the cover up to expose the top side of the left footwell
, you should be able to see the CDI Box - you don't have to remove the CDI

There are numbers on the face of the CDI:

-2002 SRX CDI [with DCS] = 8DN-30
-2001 SRX CDI [no DCS] = 8DN-20

A few people were installing the 2001 CDIs in the 2002 SRXs to elliminate the DCS system.

Let us know.

interesting read on the 2002 SRX

--------------------------------------------------------------------------------

Found this article,thought I would post it for you 2002 SRX owners:
Top Performance: SRX
Yamaha states that the SRX is based on industry-leading engine technology like self-cleaning power valves, 3D ignition system, liquid-heated flatslide carbs and new for this year is an automatic detonation control system.

The SRX is for the go-quick guy. Based on our 11th annual Shoot-Out results the SRX can zip through a quarter mile in nearly 12 seconds flat. That was the best out-of-box experience we've seen at any Shoot-Out. So the performance is real.

Yamaha's Detonation Control System allows leaner production carb settings to reliably produce increased power. Since the mix is leaner, the sled gets improved fuel efficiency.

The DCS monitors combustion vibration for signs of possible detonation, which may come from poor fuel, water or contaminants in the fuel. When detonation problems are detected, the ignition timing adjusts until detonation ceases.

When the DCS reacts, you get up to three stages of action:
1. Upon initial detection, the ignition timing retards 3 degrees;

2. If detonation continues, the timing sets back 6 degrees and you see a quick flash from the console mounted warning light;

3. If engine-damaging levels prevail, the ignition reduces top revs to a "limp home" mode of 6400 revs and the indicator lamp continues to flash. When the detonation stops, the system automatically resets itself.

We found when test riding an SRX with regular grade fuel and jetting set 10 jets too lean for Midwestern riding conditions that the sled automatically retarded itself. When we held the throttle wide open in spite of the monitored warning, the sled backed down to 6400 revs, reset the ignition and then climbed back out until the jetting and low grade gas once again required a sensor reaction. We couldn't burn the engine down. And we were trying. This will most likely be a coming feature for all future sleds as it beats the Polaris dual mode switch in peace of mind for owners.

Key 2002 SRX features:
• Dual bulb halogen headlamps;
• 145 horsepower, 700cc Power Valve-equipped three-into-three triple;
• Dual-piston hydraulic brake with inner ventilated rotor for improved cooling and stopping power;
• ProAction chassis and suspension systems for flat cornering and high speed performance;
• CNC machined exhaust ports;
• Powder metal forged pistons;
• 300 watt ignition with 3-D timing;
• Plastic skis;
• End Goal: Maximum horsepower and quick accelerating machine for very competitive riders.

I have this artical in hard copy at home as well.

What has always stuck with me is...

According to this description, we could be running our DCS Yamahas all day in the 3 degree retard mode and never know it , because by the time the DCS activation light flashes... we are already in the 6 degree retard mode!!!

Things that make you go HMMMM?
