83 kx 125 restoration & first start-up problem

[QUOTE="thunderkiller, post: 1334234, member: 102903"] Hi to Everybody, I am a new user friends. I live in Turkey. I have a V-strom DL 1000 as my primary bike. 4 months ago I bought a very old dirtbike like a toy to learn about 2-stroke dirtbikes having 83 rm 125 chasis & 83 kx 125 engine. I am trying to re-built it. The chasis is ok now, all bearing, swingarm, suspension etc. renewed and in great condition now. About the engine; I have renewed all the bearing at bottom end and rebuilt the top-end with wiseco piston&rings & LA sleeve. During my internet surfing I found this great site. Now my question; After rebuilt the top-end, I tried to start the engine but couldn't be succesful until I put some fuel from spark hole. After that it burned the fuel 2-3 seconds and stopped. I again tried to put some more fuel from the intake manifold and tried again then it burned the fuel again for 5 seconds. But newer works again after my 40-50 start-kick in two days. This time I tried to create more pressure diff. by closing the carburetor air filter side by my hand (manually choked it) and it again works for 5 seconds and stopped again. I think I have a carb problem although I cleaned it -I have a good spark ark that can be seen with eyes. -I didn't measured the compression but I'm sure that it's good although it is a complete new top-end and it burns the fuel if a put the fuel manually. -reed valves seems in good condition, no space I can observe, they completely close. -Carburetor fills with fuel in correct level. -the exhaust pipe and air filter not connected yet because the engine mountings needs to be alligned why the chasis and engine are different brand. I cleaned the carburetor before trying to run the engine. what could be the possible reasons and your recommendations to check about this issue. thanks in advance [/QUOTE]
