Original Jetting spec for a 1988 KTM 125SX

Recommended Posts

Hello All

Could you please help me find the original Jetting specs for a 1988 KTM 125SX?

I have been searching the internet for a long time and I have not been able to find this information.


My bike has a Dellorto PHSB35 MD carb with the following jetting specs:

Slide: #40

Needle: K40, top slot

Main Jet: 220

Pilot Jet (long jet): 70

Other Jet (short jet): 55


The bike was purchased in the German Alps a long time ago and I suspect it has been jetted for high elevation. 

It will be ridden at sea level, in Iceland from now on.

I am sure this info can be found in the owners or shop manuals, if someone still has one.

Hope some expert in here can help me out,
