Been on the road from States for last 10 months. In Santiago, Chile now. Bike needed lot of maintenance so I took it to my friends shop and did lot of work on it in last few days. After putting it back together last night, I started it and it worked fine. Didn't ride it. This morning I tried to start it and carburetor started leaking on the out gas line. Non stop until I closed petcock. I managed to start it and take it for short ride but it kept sputtering and dying and it sounded horrible. I did nothing on carburetor past few days and it worked great before. Closest I got to carburetor was doing valve clearance. Later today I took carb off and cleaned everything. Petcock too. Put it back on, no leak but bike barely starts and keeps dying. Really strange and not sure what to look into now. I took it off again and installed carb from my friends klr but it was late and couldn't start the bike because of neighbors so I'll try in the morning. Only thing that was done in the meantime from last night when it worked fine and this morning is that my friend welded my kickstand with the kickstand on the bike and battery connected. Not sure if that could have mess something up!? I replaced my computer with one from his bike today and problem was still there. Any suggestion?
