04 EXC RFS wont start

I have a 2004 EXC RFS. Only has 350 miles on it. It has had the 350 kit installed about 100 miles ago, and some carb work, (I think an SX needle installed, but don't remember for sure). Bike ran great, but as time went on it became harder and harder to start. Then wouldn't start at all. Since it had 350 miles I suspected valves. Adjusted the valves to .005, (I'm not a mechanic, but have done my share of motor work, although not on a KTM, pretty confident I did this correctly though). The bike still doesn't want to start. Carb is getting fuel. Spark is good, and it has a new spark plug (old plug was I nice light brown color). No visible cracks in any rubber. Any other ideas??

Time to check the compression! Gas, spark & compression should start!

just a long shot, but my bike had similar symptoms and it was my fault as i had run the breather tubes up in to the airbox without making a T section in them causing the pipes to have a "U" bend which water got into and quite happily sat there causing me more stress than you can imagine :lol:

Just a thought :applause:

Found some "stickies" in the carb. Problem solved.

      I have a 2007 450 EXC that I recently installed a new clutch slave cylinder on. Per the 2007 KTM service manual it clearly states that the clutch needs to be filled with hydraulic oil, which I did (magura blood). That was yesterday. I went out to double check the level today and when I removed the cover, the rubber seal was all contorted and out of shape. I then looked at the cover and it's a Brembo clutch and says "DOT 4 brake fluid only".
      I flushed the line and the master cylinder about 7 times with DOT 4 brake fluid and there was no sign of the magura blood left in the system. My question is: other than the rubber boot on the master cylinder, what damage might have been done by putting in the hydraulic oil? It was in for about 24 hours.
      Thanks in advance for any advice!

      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?
