[QUOTE="pdee4t, post: 167152, member: 1594"] hi guys. i have a KTM 450 EXC 2004 model. lately when i go to start the bike, its VERY hard to start. so much so that sometimes it even drains my battery trying to crank it(using the e-start). today(with a full battery), i had the choke engaged and i noticed while the choke was engaged, the bike had heaps more trouble starting/cranking...but with choke off, the bike cranked/started as it should and at least tried to start. when it did start, it stalled when i twisted the throttle(after about a minute of the bike running). during start up, there is a pretty strong fuel smell, kind of like its flooded but there isn't any fuel leaking out the overflow hose. im wondering what the possible issue could be? i am thinking its possibly fuel related. unless the new starter motor has already gone or on its way out. im just confused because i don't see how a carby/fuel problem would stop the bike from cranking....? I have ruled out a lot of possible causes: -checked all valves, all are in spec(if anything, they are 1mm loser with a 0.13mm gap as opposed to 0.12mm) -checked for spark, has strong spark -brand new spark plug -has a brand new starting system on it(starter motor, starter solenoid and battery). -fuses have been checked -also replaced the stator and upgraded my regulator/rectifier not long ago, to match my stator. -bike is timed correctly(as per manual). checked all the timing marks. -took the carby apart, jets appeared to be fine(not clogged).
