Ktm 504

Hey guys,Steve (aka Fossil) here.New to the site,as a member but have perused the pics quite a few times.Great stuff! Got a question. I'm a two stroke guy and have just picked up a '83 KTM 504 (Rotax powered of course).It needed some work and had sat for a few years.found the parts,wrapped it up then............ started trying to kick start it. Kicked until my leg was cramping:choke,no choke,throttle,no throttle,every combination.It started a couple of times (for about a second) then nothing. So,I hooked it up and pulled it off.Started right away and ran great.I assumed it just needed to spin up faster and pulling it off had cleared it out and would start after I ran it a while.While still warm,it did start; but the next day, after it cooled down, same story.Does anyone here know the correct starting proceedure for these beasts? Any help would be appreciated.Thanks,Foss.

Check valve clearance. If that's good leak it down it may need a valve job.

If you need a factory manual for it, there's one on Scribd that I uploaded.

starting procedure on mine :
full shoke ,
put the engine just over TDC one kick should be enough.
sounds like the carb needs a good cleaning

I have found that it is necessary to think of oneself "Pushing" the kick starter through on a 4-stroke and not "Stabbing" at it like one does with a 2-stroke. The kick itself should be one long fluid accelerating motion. You have a fair bit of mass to accelerate and just flailing at the kicker will often just tire you out.

On all of my thumpers I push the kicker over slowly until I'm on the compression stroke then open the compression release and ease the motor over to just past TDC. Then a steady smooth kick to get everything moving. Each motor is a little different, but there is a technique to getting the kick right. Once you master it you will find you can amaze your friends by being able to start any thumper you encounter.

Assuming the motor and carb are all happy and clean, etc.

One of these ?
I saw this between races at Mid-Ohio one year and made a bee-line for it. The guy that had it had just purchased it an hour or so earlier. I checked it out made an offer and we dickered awhile. And I bought it.
They hadn't been able to start it,but, they said the other guy had filled it with oil. All the way up with oil as it turned out. The frame , which is the oil resivour was filled to the top with oil. Not good since the bike only holds about 2.5 qt.s.
Anyway the carb on this one was clean and I gave a strong kick and it lit right up. And blew the oil cap out of the frame followed by a 12' gyser of oil.
After wipeing the oil out of my eyes , I drained the oil completely, added the correct amount and had a nice ride around the grounds includeing the woods over the hill behind the backside of the track.
On your bike , clean the carb espiicially the idle jet and it should run.
