I just bought a 2008 ktm 105 and i can start it okay but when i pull in my clutch and push down on the shifter for gear 1 the bike shuts off.

to me this seems a case of many things not 100% set up properly.

big singles do burn a lot of oil, so either its low or just the wrong viscosity, check with a KTM forum as a lot of users will have already had this problem and rectified it.


but the first thing i'd check first is: Idle speed (if its FI then shouldnt be a problem) valve clearances and it also depends on whether you have any mods?



a race spec pipe will always cause issues starting cold.

I had the same prob with my bike heres what i did.. I took the cluch all apart soaked all the clutch plates in oil. Than i ordered new clutch springs from <Motosport.com.> Than put all back togeather and rebled the clutch and it work like a top.. HOPE THIS HELPS..

1.If the bike has been sitting for some time the clutch plates may be dry- remove plates and soak in oil overnight.
2. Check steel clutch disks are not warped
3. Clutch has nine friction discs, 8 larger ones and one smaller(the inner or first one you install). Inside this diameter of the ninth friction disc is whats called a judder spring, one flat and one concave, check that the concave faces inwards check that the flat one is installed first.
4. Bleed the clutch as per the manual, in reverse.
5. Check clutch throw with clutch cover off and clutch plates assembled. Watch the pressure plate for movement, should move around 3-5mm.
6. Try a 10W oil instead of 15W(Motul)
7.All else fails, **** the judder spring off! I did this on mine after days and days of rootin about trying to stop the bike walking forward in gear with the clutch in!! and it was much better! Judder spring is there I believe to make the clutch a bit smoother, didnt make any difference to the smoothness of my clutch but it stopped the bike walking forward in gear!
Hope this helps mate!

Hi Art! First of all, congratulations on your 1967 Triumph... that's a beauty!!!

Basic things to know before riding a bike is it's parts.

Clutch is the lever you press on the left side of the handle bar.

Front disc brake is the lever on the right side of the handle bar.

Shifter is the one you're stepping on when shifting gears and is located on the left side of the engine if you're on it.

Now, you must first know if the gear is on Neutral by pushing the bike before starting the bike. If it's hard to push then the shifter is not in neutral. Press the shifter by your left foot until you are able to push the bike with ease.

Hop on the bike and start the engine. Most bikes have ignition starters but if your bike doesn't have one, then you have to turn keys to on position and use the kick starter. Rev the engine by pressing the throttle grip on the right side of the handle bar.

Engine is running and in idle position. Press the Clutch lever (left hand) and press the shifter once (left foot) DO NOT RELEASE THE CLUTCH YET!!!

Slowly press the throttle with your right hand until you hear or feel the engine purr...

Slowly release the clutch (left hand) until you fell the bike move forward.

If I am not mistaken, shifting the gears of the triumph is 1-down and 4 up...

Every time you shift gears, you need to press the clutch to release the gears.

Hope you'll have fun!!!

Ride safe my friend!!!

Don't forget your riding gears!!!

G'Day mate,
Sounds like the bike has a stuck clutch, where the pressure plates and clutch plates are not disengaging, probably from sitting for a while. Check the clutch adjustments first to see that you have good operation and tension in the clutch lever. To break it free, try first allowing the engine to heat up to operating temp, this can sometimes allow the clutch to free up with heat expansion.
If you can get the bike to a rolling start(mate pushing) and get into a gear, go roll on and off the throttle a few times with the clutch pulled in, see if you can break it loose. Some peps have success with wrapping wire about the handle bar holding the lever in, and let it sit over night, let the oil into the clutch plates.
Dont get too carried away with dropping it into gear with the engine running. You dont want to do more damage. If it remains an issue, you will have to remove the clutch cover and tear the clutch down. check plates for wear and warping. Replace if required. Good luck with it.
regards robotek

It sounds like the end of the shifting shaft has broke loose, it is a welded joint, If you can grab the shifter with your hand and feel that thing slip in there, up and down,that might be the problem, but splitting that case, ugh, total rebuild.Too bad you can't get to it through the clutch. Hope this helps.

pull your clutch in on the left handlebar push the shifter lever down and let you clutch out slowly while giveing the bike a lil bit of gas. But if you don't know how to ride i wouldn't be jumping on a kx 250

this is the same with all 4 strokes. they all need to heat up before you can ride them, but this is not a problem.
