revving & bike stalls

Driving through town, malls, parking lots, I'll rev my binge by pulling in the clutch.

Not a huge rev, just a cautionary one.

Yesterday & the day before the bike stalled.

Fortunately it's got a start so I managed to turn on the bike while still on the move.

Why does this happen?

Sounds like a fueling or low idle issue. Otherwise called a flame out.

Tuning issue (too much or too little fuel) or idle too low would be most common causes. Overly tight valves could also contribute. Did you change anything just before the problem started?


Doesnt happen every time.

Sort of like after it 'builds up'.

fuel filter

gas cap vent

damaged plug

filthy air cleaner

corrosion on injector nozzle

Did the problem start suddenly, or has it always been this way?

Suddenly started.

Fuel filter was changed 5 hours ago.

I also have a tank sock.

Our fuel is very clean as well.

The others are unlikely.

Bike only has 50 hours of light usage.

I would first check the valves, over tight valve clearance can affect idle. If that doesn't do it I would check out the injector, maybe it's partially clogged or leaking.

where is the idle, that will definitely cause it , needs to be atleast 1300 rpm. if you have a strong idle, but still an issue, then its the fueling set up.

Idle and TPS, my 2012 and now my 2015 would do it every now and again.  I have a bad habit of blipping the throttle due to years of track riding sportbikes, catch myself all the time when going into corners or coming to a stop quickly.  My 2015 was doing it 3-4 times a ride with the TPS at .63 and the XCW map, went down to .61 and it runs perfect - not one pop stall since I leaned out the TPS setting a bit.


In addition to the XCW map they both had open end caps too.

      Hi Folks!

      Sorry if there are a bunch of threads already but I used the site's search function and didn't find anything so far...

      I just found a decent deal on a '14 350 EXC-F with 11k km (unknown hours). Has a few goodies including skid plate, hand guards and it's for sale for about $2k CAD less than a '16 with 6k km on it.
      The bike is in showroom condition (appearance) with no indication it has been offroad at all.

      What would be the gotchas that would make this deal realistic? I'm coming from a WR250R where the engine lasts forever, is 11k street kms high for these bikes? 
      Are there any big defects in the '14s that I haven't dug up yet?
      With no service records what things should be done, checked, etc?

      I purchased an '06 525 EXC some time ago, and recently pulled the motor out of the frame to address some other issues. When I removed the clutch slave cylinder, I noticed an issue the previous owner neglected to tell me about during the purchase.
      It appears that at some point, the chain broke and damaged the engine case near the clutch slave cylinder (see pics, please). I have noticed that the clutch does not fully disengage (bike lurches a bit going into gear, neutral is hard to find... its worse when engine is cold) ... I did not notice any leaks around this area (mineral oil or engine oil) before or during disassembly. 
      The previous owner (or someone) repaired it with some sort of epoxy.
      Without doing my due diligence (checking clutch fluid level, bleeding) I hesitate to state that this is the cause of my clutch disengagement issue ... but pardon my ignorance here and help me out: How bad is this?  Am I looking at replacing my engine case here or is the previous owner's jerry rig good enough?

      SO, for information sake and to power the search engines with some key words that i couldn't seem to trigger during my research...I'm posting my desmog process on my new 500exc. Being a new bike...i wanted to make sure that all of my "doings" were going to keep the short excuse for a warranty in tact. I have part numbers for the plugs, washers etc as well as what all came off of the bike. I know it's a simple process for some, not so for others and would like to give credit to the writeup for some great info.
      Long story short...i plugged the hole left from the smog pump thingy on the right side of the cylinder, the Secondary Air System (SAS), the overflow canister, and all the hoses/wires that go with. The electrical plug that was involved I simply taped up with grease in it and strapped it to the inside of the frame rail.
      After i took all of it off, it would not idle....i turned up the idle adjuster (to the left) or counter clockwise in order to increase the idle speed.
      Result!!!!!! NO popping on decal, no stalling after hard accelerating, etc. Sometimes after much creeping and low rpm riding it will load up and flame out. I plan to try a different map after i install my exhaust. I think a new map will be able to add some rev to the top end. Right now it seems kind've flat once you pull through the sweet bottom and mid ranges. The bottom end power of this bike coupled with the silky smooth clutch action makes for the easiest and best suited off road bike i've ever been on. It does what i need it to do!
