Question about 2005 KTM SX 250

1 Answer

Bike dies as soon as it is started!

I just bought a 2005 KTM 250SX tow stroke and I am having a little trouble with getting it started and keeping it running! First thing I noticed is that the choke won't stay up it just falls back down like its being pulled... Second, it leaks fuel like crazy out of one of the houses coming out of the carb and third once I let the choke fall back down the bike immediately dies.. Any ideas on these three things?

First you need to remove carb clean them , then new gaskets . sounds like they are glazed due to old fuel drain tank and refill with new fuel

Hi, Sagi nice novella and the usual suspects are:
1. Fuel mixture too rich or enrichner left out too long.
2. Faulty spark plug.
3. Incorrect spark plug for the engine type or service.
4. Piston rings badly worn or broken.
5. Valve guides are badly worn and/or seals worn, crushed or have come off the valve guide and are pumping oil through it.
6. Spark plug cable weak or leaking check for spark jump in the dark.

I have a 2003 ktm 250sx and when shifting at high rpm's it won't shift.


How is your clutch? Does it slip or drag when starting out? When you put it into 1st gear when starting out does the bike lunge forward? Hold it in first gear with the clutch in and rev the bike up. See if the bike wants to move forward with the clutch in.It sounds to me like your clutch isn't set right or getting worn out. Much easier to shift at low rpms on a clutch than high rpms. I hope this helps...

What could cause a KTM 250SX transmission to


Either the shift linkage could be binding or you may need to adjust the clutch.
The other problem might be a synchronizer in the transmission going bad.

Ktm wont start


sounds like you may have over adjusted the decompressor, back it off to where it was, this would make it backfire.
To kick them, push the kickstart through its stroke until you get to feel the compression as it approaches the compression stroke, then use the decomp to kick it just past top dead, let the decomp go and then kick it, no throttle

Oil


Correct me if I'm wrong but the 250SX is a 2 Stroke engine with a Gas (1.98 Gals Unleaded Premium 91 octane Recommended) to Oil Mixture (using Motorex Cross Power 2T at a 40:1 - 60:1 depends on oil quality) and when KTM says to Change the transmission oil the amount called for is 0.7 liters engine oil using Motorex Top Speed 4T 15W50. These Quanities are from an 04 250SX could not find a 2000. So consult with your local KTM Dealer's Service Department and pickup a Owners Manual at the same time it would be in your best interest. Liter breakdown 0.7 liters = 0.739681 quart (US liquid) OR 0 quart (US liquid) and 1.47936 pt (US Liquid) / 0.7 liters = 1.47936 pt (US Liquid) OR 1 pt (US Liquid) and 0.958726 cups (US)
