So I've tried to search this particular issue and I still am not sure what to do. Purchased a used 02 kx100 and it started up first kick on the test ride, was told that it had been sitting for an hour before I kicked it over. Got it home and the next day it fired up, rode it less than a 100 yards it bogged down and died. Cleaned and jetted the carb, cleaned and oiled the air filter, and put in a fresh correctly gapped spark plug. Tried it before work no go, tried it after work and it fired up on the first kick, ran it around the block all good. Three days later would not start again so I put a small amount of fuel directly into the cylinder head and started up second kick, the bike ran great and the jetting is perfect. If it is stalls it will kick over first kick but if it sits for an hour I need to add fuel to the cylinder head again. I have tested the spark and it seems fine and I have not messed with the timing. Any ideas?
