brake problems

my front brake locked up on me a couple weeks ago took the master cylinder apart got a new plunger for it an put everything back together the exact way it came out.... but i cant get it to bleed or pump up or move fluid through the master cylinder anyone have any ideas what that could be?

I have best results removing the caliper & outside pad, compress the inner pad with a small c-clamp, then pushing fluid ( and air) from the bottom bleeder, up out the handlebar master cylinder. Use of a 2 oz feed store plastic syringe works for me.

It's also a good idea to keep the brake line lower than the master cylinder while bleeding. Air can get trapped in the line where it curves up and then down towards the MC.

      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!
