KTM 950 Adventure 2004 Holding Back

Daniel Howden

Recommended Posts

Hi, I have the above bike and when I accelerate hard it feels like the engine is holding back.  It is difficult to exactly explain what it feels like but up to a certain point if I continue to twist the throttle my speed stays the same, this is riding up to 60MPH

I am new to this bike and I have stripped and rebuilt the carbs, new air filter and new oil and oil filter.

I just wonder if I'm missing something.

Thanks, Daniel.

First place I'm going to look is the carbs, were they balanced after the rebuild?  Did you install new slide diaphragms (KTM p/n 60031035000)? Tiny hairline cracks in these diaphragms are hard to see with the eye but can result in a big loss of power as it doesn't allow the needle to open fully.


Also, take your boot off the rear brake lever... 🤪
