Default Ktm 505 sx will not start

Here is the deal. I last rode my Ktm at Snow Shoe. Came home and washed it then rode it into the garage. The bike ran great at Snow Shoe. Went out to start about a month ago and it would not. It has spark and is getting fuel. I have put in a new spark plug, charged the batteries (24 Volt) the only thing that I can get is back firing from time to time. I have tried to spray starting fluid in the carb will still no results in starting. Any ideas?

Can you pull the choke and it will run? Honestly it sounds like the pilot jet is plugged from sitting. Carb just prob needs a good cleaning.

"looks good" or is good? Several of the jets in those FCR's have VERY small orifices and will plug up very easily if the carb sat with fuel in it for that long. Simply squirting some carb cleaner in them won't be good enough. I had this happen recently with a little xr50 carb and the pilot jet (non removable) was so plugged up I had to take a welding tip cleaner to get the crap out. Remove all your jets and make sure you can see through them all and they're clear.

Also have you checked to make sure your petcock is clear and working properly? This sounds a lot to me like you have some plugged up / gummed up fuel somewhere in your system.

Is the bike in a heated garage when you try to start it? I have had bikes that absolutely will not crank, then when you warm them up, TA-DA, they fire right up. Also, if you're sure it's getting spark, you can always roll start them.

I took the carb apart and did a good cleaning. Made sure I could see light through the jets. Roll starting is not a option ( rekluse ). It is getting spark with the plug out. Could it be possible when the plug is in that the compression is some how making the bike not make a good spark? The Batteries seam to be turning it over plenty fast. I had one person suggest that it could of jump time. It has a manual timing chain tensioner. Me having never had a bike with this on it. I have never adjusted it. However bike did not make any wears sounds last time I rode it. He suggested that if lose it would of ran fine until the bike was cut off and at that time it could of jumped time. Does this seam possible? I just got the Ktm service cd today so I will be able to check his theory in the next day or two. Another thing could you have a spark but not a big enough of one? Or good enough might be a better way to put it.

it is in a garage. I thought that could be a issue with it not being warm so I turned the heat on over night and tried it once more.

Wow I can't believe it took you this long to chime in. But could you remind me how many times you have been on here asking questions about your LTR.

I think you're on to something with the plug. My 450r did the same thing with a brand new plug. Put the old one back in and it fired right up.
