The members here are more knowledgeable than most of the mechanics that work on them, so feel free to ask us any question, no matter how redundant or complex. However, before you post a thread or PM one of us, please read this ever-growing FAQ. If your question is not addressed, feel free to use the "search" tab on the right hand side of the page.

FAQ
1>what is the pink wire mod? how do i do it? what does it do?
-the pink wire mod is a wire located underneath the left side of the plastics near the ignition switch. cutting this wire releases a secondary fuel map that makes your fuel mixture richer and allows for mods including pipes, filters, intakes, cams, pistons, etc. you have to remove the front plastics by removing ALL bolts and torx screws. it is located near the ignition switch. it is pink, and in a loop separate from the rest of the harness.

2>my clutch squeals. why?
-the 2008 and some 2009 clutches squeal. there is a BRP update/service bulletin that fixes this issue by adding shift pawls, an extra plate and an oil squirter.

3>my bike wont start. what should i check for?
-relays! fuses! loose wires! we have all had these fail or go out, it will happen to you, its just a matter of time. there are 3 relays under the front plastics directly infront of the handle bars. they are 3 gray cubes. they are relatively cheap at your local auto parts store. you have 2 fuse boxes. one under the seat near the battery, one near the left knee area. check them. make sure your battery terminals are clean and snug. also check the solenoid underneath the battery.

4>my bike wont go past a certain RPM, why?
-welcome to limp mode. chances are you've overheated as these quads seem to run hot. there could be some other issues at hand, such as a loose wires or an electrical issue. cool the bike down before investigating.

5> how can i keep my bike from overheating?
-swiss cheese your plastics. use a hole saw to cut holes under the fenders to help heat escape. use heat tape on the bottom side of the gas tank to help keep fuel from boiling. BCS sells an extraordinary in-line cooler for your radiator lines that helps. also try adding water wetter or switching coolants to Engine Ice.

6>what will a FMI unit do?
-FMI units are piggyback fuel management systems that override your stock settings. they can be custom tuned for your mods, and you can alter the fuel input per throttle position. tuned properly they will help unleash all the horsepower in your new modifications.

7>do i need a FMI unit?
-no. there are plenty of riders running only the pink wire mod with great results. the FMI unit is not a necessity for modifications but it does help with on-the-fly tuning and altering the fuel curve for different styles of riding (drag vs mx for ex)

8> my rear brakes are gone! what do i do?

-alot of riders have had problems with the rear brakes failing and loosing pressure. what you need to do is remove the reservoir lid and slit the rubber cap that is on top. then bleed the system until pressure returns to the pedal. the rubber cap creates a vacuum and the oil cannot feed the caliper. slitting the rubber cap will eliminate the vacuum.

9> whats the best exhaust for my quad?
-never, ever, under ANY circumstance, start a new thread on this! there is no best exhaust! there are many, MANY great exhausts out there, some have more hp, some have lower db, some look better, etc. its all about your riding style and how much $$$ you want to spend. as of right now, Ron Woods (rotax.net) has the throne. his exhaust makes the most hp and has the highest gains across the board. Rossier (rossiereng.com) is a close second...these two guys have the most rotax knowledge and are great sources for information regarding power and efficiency. motoworks helped in the design of the ds450, and they have a power package that BRP actually offers to its racers directly. it is also a great exhaust choice, and much more affordable than the other two mentioned. HMF, FMF, yoshimura, etc. all make pipes for the ds as well. please do a topic search before asking about what we here at the forum think would be a good choice for you. there are many dyno sheets on the forum as well as each manufacturers website if you need them.

there are many things to check for as well:
front frame rails where upper a-arms mount for cracks
grease all bearings and carrier
spark plugs and boots

OIL:
1.8L
Oil washer: 12mm copper

At what hours are you supposed to change the oil? I have read to change at 5 hours
and also the first change should be at 10 hours. Which is it?

Depends on your use. Alot of the racers (extreme use) will change their oil from every race to five hours. Average riders will go ten hours. Then there is the type of oil. Which there begins another chapter.

So it all comes down to personal preference. Although if you use Can Am reccommended oil their interval is 10 hours.

Just a tip not a mod.

If your going to hook your battery to a charger, disconnect the battery from the quad and then charge it or it will burn out your computer system.

Great thread!!!
Too add to this use lower amperage (1-2) and you shouldn't have any issues.

Using a car sized battery charger on your Ds's battery isn't a good idea.
