650 outlander stalls (sometimes?????)

[Ron H]

I hope sombody else has experience with this. I've an 07 650 outlander, what basically happens is after running for a while the bike will shut off while stopping in or out of gear.
The precurser to this is the speedo needle will "bounce irratically". Now I've done fuel filter, plugs, exhaust, air filter, oil change, injector cleaner..(What'd I Miss???) I did take it to Marten equiptment for a Puter read out and cleaned the altitude/oxy sensor (Carb Medic). Still no difference.

the speedo part makes me believe its a computer problem.

tell me more about the stalling. it happens both when the motor is hot and cold?

 

[Ron H]

No it runs fine till it warms up, then the stalling starts. I can however immediately start it. Sometimes it runs fine for a bit others it stalls right away.

 

[Ron H]

I did think perhaps a plugged muffler but no change after a new one. I was also considering a fuel pump but temperature should have no effect . The fuel tank has a new breather line running to the air box and it is clear. In the last 2 months I've done quite a number of mods but I don't see how any of them could have any affect though. Just in case here is what I've done:
Exhaust, Snorkle kit, clutch kit,rad relocate, lift kit, tires &wheels, general stuff, no engine mods or electrical type of stuff.

 

[steveo10]

temperature actually is a factor. likely its your fuel pump failing. you should have constant fuel pressure

 

[Ron H]

How would I test for this? How would engine temperature affect the fuel pump?

 

[steveo10]

its not actually the engine heat, its the strain of working the fuel pump. install a pressure guage on the feed line to the injectors... that will tell ya a story

Are you running marked fuel?

 

[LBZ]

Are you running marked fuel?

I think I know where you going with this and it doesn't matter. If it did, alot of seadoo's and boats would be f'd.

I too would check the fuel pressure. Does the engine just stall or does the display and everything go blank?

 

[DaveB]

CanAm's are famous for doing goofy things when the battery connections are dirty or loose. Sounds dumb, but it's the first thing to check. Check the two fuses at the rear by the battery too...they get all corroded. THEN check your fuel pressure, etc, etc....

 

[any1butjj]

there is collection of grounds near the battery, pull them all off and clean them up, a little sand paper helps. re-assemble with dielectric grease. Had a similiar problem with my 2007 Renegade.

 

[Ron H]

LBZ: Only the engine stalls, the display stays on....
Dave B: There is a new battery as well, that was one of my first thoughts as the old battery was dated "07". I Did clean the two 30a fuses at the rear, been idleing for 1/2 hour and good so far....
What funtion are the two fuses?

 

[Ron H]

any1butjj: That makes a whole lotta sense in terms of preventative maintenance as well, this bike was factory (no mods)and trail ridden in BC till I got er a couple of months ago. What else should I be doing as this bike is now doomed to a life of mud and water. I was considering taking all electrical joints apart, cleaning then given em a smoozey with liquid electrical tape to seal em. So far everyone I've taken apart has been cleaned with contact cleaner and carb medic but I ve not used the liquid electrical tape yet or is this a bad idea?.

 

[DaveB]

The two fuses are the main power supply.

For mud/water...take every connection apart and dielectric grease them. Get to the main harness under the pod as well.

 

[Ron H]

Pod? What is this pod you speak of and where is it? Sounds like a fair major undertaking I'm not so sure about this one. I've done everything else to my bike but these were more Mechanical though, ellectrical is above my pay grade so to speak.
Perhaps you want a job.... I'll pay and help (do most of the physical work with guidence) all at the same time so I can learn. I just want to get er done right and not be the guy who has to hire a helicopter or something goofy like that. There are many currencys I deal in, Rye, Rum, Vodka, Beer, Burbon and of course good old fashioned Cash...or any combination thereof...

 

[DaveB]

LOL. It's not that bad. Pull seat off. Grab plastic that surrounds handlebars/guage/shifter and pop it off. The pod is the speedo....you will see the ECM under there.

If you are going to give it a life of mud and water, you MUST consider snorkles....at least the CVT exhaust must be raised. Where is your home base?

 

[Ron H]

I'm in Edmonton North end. I have it snorkled and rad relocate already. Pulled some wires (I believe that ground cluster)cleaned and dielectric grease ,,,it got worse? now I can't start it unless I give er gas now.

 

[DaveB]

I suspect you are at the check fuel pump output point.....

Fuel pump should put out 51 psi. There is a filter sock on the pickup inside the tank...if it's dirty, the pressure will drop. With a gauge on it, it should hold around 50 psi even at sustained WOT.
