I know it's probly been discussed on here before,but I want some opinions. I am buying and SRX to play on the ice with and have it narrowed down to a 01 and 02,which one should I buy? is the DCS a pain on the 02?

CAN,T MISS WITH EITHER. 3:16 (yammie tony)
Guys say DCS can be a pain but think about it, with no DCS on the '01 it may go faster...that is until it goes pop!

i would go 02 way nicer looking and the DCS can be your friend if your using good fuel

Hey guys i was bored at college just doing some reading what is dcs? and isnt there no differance in the srx from 00-02?? just wondering i think this guys making an awsome choice goin with one regardless

DCS senses detonation and lets you know the easy way that you have a problem.

does dcs slow u down if it blinks?

yes it will retard timing ..

right away? or only if it senses a knock

My sled with good gas only blinks the DCS on a loooong hard pull. 2 weekends ago with 3 gallons of 110 and rest 93 I held it WOT and dragged with a fast 03 F7 for MILES without letting off and not 1 flash of the DCS. nuff said...

what if i ran pure race fuel? would it run rite
pure race fuel doesnt work with current jetting

k, how much should i put in?

They like 100 octane. Just put a couple of gallons of 110 in with 7-8 gallons of 93 and give it a try. No more DCS

Found this in a search
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.

Very cool. I have read "how the DCS works" several times, but this part about attempting to burn it down and couldnt is new to me...
