my two cents - or one man's opinion from a thousand feet
my power steering was butter smooth in the first 5k miles. I could navigate curves with one hand and often goofed off doing things like leaning off, waving to the side or just gliding through a curve.
Chapter 1;
Somewhere after 5k miles the DPS became unpredictable. The same curves that I once navigated with such ease would now be completely unpredictable. Sometimes as I entered the turn, the force to make the turn suddenly became so great that I would have to get off the throttle and use upper body strength to make it through. I'm talking slow speed turns on back roads and not on the highway. Under 30MPH but still fast enough to generate some panic because even at 20mph a tree will hurt.
Symptom number two would be instant increase or decrease in steering while in the turn. This really started bugging me because now I would enter a curve feel that it was hard, pull with extra strength and then suddenly the steering would break loose (DPS kicks in) and now all that extra force is not needed and I'm actually pulling myself in to the other lane. Now we are reaching higher levels of panic cause I don't want to hit the front bumper of a Buick. This also started becoming a serious issue for me as I navigated NYC traffic before and after work. Weaving from lane to lane I need to know how much force to use and what to expect.
I spent alot of time at the other forum and posted this info there. A few other folks talked about it but I also read enough horror stories about it not getting fixed so I was not about to run down to the dealer. ( I have an issue and I don't want to stop riding) I was not at all excited by the idea of leaving it with the dealer while everyone attempts to discover what is wrong. One person described a situation where the dealer received a new DPS unit with a newer part number than expected and this new part number caused issues with their computer system. So although they installed it, it threw codes left and right the second the engine started, so it took 4 weeks to get his ride back.
Doing all I could to avoid placing myself in that kind of situation I instead pulled the front DPS control fuse and boom. Now I had no DPS at all. I'm ok with that cause I'm strong enough to move the bars and now I never had to worry about it coming and going.
Chapter 2;
I read on the other forum that someone's dealer had discovered the DPS unit would eventually get warm and start drawing more power than it needed. By testing the amount of power being pulled in at start up and then checking again after a 30 minute ride. After the ride the unit was pulling way more than it should. (i never noted the values)
When I first started having issues I noticed my fender lights dimming as I applied pressure on the bars. It would not happen in the morning but as I approached the end of my 90 minute commute and sat at red lights, I could give a little push on the bars and the lights would dimm down as well as my RPMs. Now we are in the 10k - 15k mile range and now when my rpms drop down in traffic my engine seems to want to stall. Eventually its does start to stall on me.
After an unknown amount of time my engine would just start dying down as if it was dying... and I started thinking about that phantom power draw at the DPS. "Was it draining my battery?"
The few times that it did stall I would be able to just fire it back up, battery light would flash, I would rev it up for a little bit and then all would be well again.. Anytime this would happen I would also start to get a really strong gas smell and I would start backfiring like a popcorn maker. I would approach red lights, let off the gas, pull in the clutch and my RPMs would drop down as far as 1k. If I was not ready to give it gas, it would just stall out and my gauge would blink as it does when you firt put the key in. (gauge needles fly up and down)
Chapter 3;
Needles to say this became a hassle after a while. Then the idea came to me. Although I removed the front DPS fuse, that is not the main DPS fuse. So I went to the rear panel and removed the large DPS fuse. My thought was that maybe the DPS device itself is still drawing power as the front sue was only for a switch to tell it to work... (don't how true this is, its just a thought)
WoW!
No codes, No DPS at all, RPM issues no longer there,
flashing battery light in city traffic = gone,
strong gas smell in city traffic = gone (and yes I still overfill sometimes to the point of spilling out)
backfires in city traffic = gone
stalls at red lights = gone
I start noticing a difference about 50 miles in to my first ride after removing the rear fuse. The Spyder runs like new again. I've logged nearly 4k miles this way with no codes and the engine is running great!
I dropped the Spyder at the dealer yesterday for Tires, brake pads, rear bearings and to replace a faulty oil pressure switch. I also specifically asked them to not touch the DPS, just leave it alone. I'm still riding with heated gear and I don't care to be a guinea pig to have this gremlin tracked down. I'm perfectly happy wihtout the assistance of the DPS.
I take the time to put this in here just to share the information and not recommending that you do the same. Just sharing my experience.
There is life without DPS....

I'm not a mechanic or a CanAm tech so its entirely possible that whatever was causing me issues was not the the DPS. The fact that all my problems dissapperaed at the exact moment of me removing those fuses could just be a coincedence.... or, may not
