Yes im afraid this is another "Help wont start!!" post but I have done basically everything. I have a KLR 250. It sat for a couple years (with gas) and recently I wanted to get it up and running. took the carb out and cleaned it (Boiled in hot water then blew out the needles and other areas with air compressor) and I also took out the air filter and cleaned that. After doing this I attempted to start it, after a couple kicks, the gauges and front light would light up and the engine would rev, but then immediately die. Then it would not do this again for about an hour. I considered changing the spark plug but if it was a problem with the spark plug wouldn't the bike not start at all? Is the idle maybe to high or to low? how would I change that? Was I wrong about it being a problem with the spark plug? Any help is appreciated.
