Question about 2001 KTM Adventure R 640

1 Answer

2001 KTM 640 adventure I am having a problem keeping it running. I have to keep on the throttle to keep in running. It idles rough and then cuts off. It is also blowing a very little bit of black stuff out the exhaust, especially when I rev the engine. The motorcycle sat for 3 years before I bought it in hot humid environment, but I have had the Carbs cleaned 2 X in last 18 months i have been driving it. The choke cable is damaged could this be the cause? Or should I be looking for something else?

    the Choke can cause the black stuff coming out of tail pipe as well?

Replacing the choke cable could verywell fix it but for a quick fix till you get one on the carb you will find a big brass screw its for your idle you can turn that up just a little to your idle prefrence

that does no damage
