hey niven this isn't IM.....you need to switch the page for that.there is 2 little figures at the top right of your screen click on them and type.

I have never had a start issue yet for some reason.I always have turned the gas off when i parked my bike...I doubt anything to do with this but maybe a thought.I also once had a KDX250 that wouldn't start at all unless you leaned it way over against a tree till the gas came out the overflow...it would then fire on the first kick.If you didn't do that you could kick that thing till your leg fell off all day and it would never start.I just always thought it was a crummy carb design or type that made the issue....My Honda atv uses a carb with the same jets and needle as the klx and that thing can sit for 4 months with the gas on and if i pull the choke it fires on the first blip of the button.

Try this.open your fuel tank first before starting the bike ....that is assuming that all the bikes here with this problem have the stock tank on them yet.A pressure change in the tank could do this.I have already opend my tank to hear a pressure vent.just a thought.

 

Okay..it's been well over a week..BTW..I always shut off the fuel switch as was told long ago doing this saves the diaphragm in the carbs (not sure if that applies here but just a habit i kept)..when i left it over a week ago, fuel was shut off, then a couple of blips on the throttle, then killed via kill switch and then ignition off..had cold weather here for the past week, even some snow (bike is stored in cold garage though), but today finally got up to +3 degrees celius so I decided to start her up..wouldn't start at all..no freakin way, tried wide open throttle, tried fuel off wide open throttle, tried choke off fuel off , i mean everything no go, even the battery was starting to get run down, then i remembered someone what someone else had down...tipping the bike on its side for a few secs and back up, started right up..I just don't know, but it definately appears that the gas in the bowl is a really big part of the problem (I believe someone already mentioned that, now i amdamn nearconvinced, but there must be something to fix this other than adding the stabilizer to every tank)..I just don't know.[&:]

 

Hi All,
Such an interesting thread I thought I better register with KF and give you my tuppence worth as I also have experienced the same problem with my 6 mth old klx250 . While I am not an expert I believe the causes of the problem (as advised by local bike mechanics and which some of you have touched on),are as follows:
1. the carbie is highly tuned with very fine jets to meet EPA standards - that is why I get such good fuel economy of30+ Km/litre compared to my mate's Honda 250 which runs about 20+ Km/litre.
2. fuel is not as good as it used to be because of the various additives which can 'gunk up' the system (read jets) - that is why it is necessary to empty the carbie bowl either by turning the tap off and keeping the motor running until it is dry or uncsrewing thesmall bolt at the bottom of the carbie bowl.
The other solution if to rejet the carbie.
What I have begun to experiment with is - once I determined how long it took to empty the carbie with the motor running, I would in future only run the motor for 2/3 to 3/4 of that time and then turn off the ignition switch. That way I avoid the motor getting too hot (and ultimately damaging valves) because fuel mixture does not become too lean. The next time I go to start the bike the carbie is only 1/4 full with old fuel and is filled up with fresh fuel when I start up. Seems to be working OK for me at this time (in a hot climate).
By the way I suggest this is a design fault in the KLX250 and I wouldn't be surprised if some dealers rejet the bikes before they sell them so as to avoid warranty hassles and to ensure the model doesn't get a bad name!!

The big question is....what is actually taking place when you tip the bike? Is there a transfer of fuel from bowl to tank? Is an air pocket Un-trapped? Maybe the float un-sticks? I guess the easiest fix for now is to just tip the bike. Does it matter which direction we tip it? Also, does any gas leak out of the tank?(that would Suck)

 

pulling out the choke slowly when starting works, I do it all the time. I just started it up after it sat for a month and it was 30 degrees.I did not drain the bowl when I parked her either. Some others on this site also do this, that is where I got the idea.
