It makes sense for one part to be the pick up sensor and the other a ignition advance module

KTM Motorcycles | Answered on Nov 09, 2014


All being as it should it is either ignition or fuel problem. Check air filter is clean or take for run without to see difference. Do a hard cut to check spark plug reading for lean out or fouling (run engine open throttle until high revs snd cut ignition while closing throttle and pulling clutch in to stop engine. Check plug lead. Change plug. Ignition grounded. All the basics

Hello,
there must be a "safety unit " on your Ktm. It reads all the sensors ( tilt, neutral, clutch...) it could be faulty. If your bike doesn't have one, then the ecu does that job....
i have seen this problem on a good few Suzuki's and aprilia's when the tilt ( angle sensor) was faulty or badly relocated (when someone had fitted an alarm or changed the battery, they had it upside down).
I hope this might help you

Drain the entire system and back-bleed it from the slave cylinder up with a syringe.

If the bolts are spinning you will have to drill off the bolt heads and extract the threads from the base inserts. Replace the petcock base o-ring, epoxy the base nuts into the tank body, install petcock. Or replace tank and valve. It's a choice of time or money.

Carburetor issue. Running to rich, water in carb and tank, or filthy air filter

The ring is too keep the pipe from damaging the cylinder.
The o-ring on the pipe is what seals it from leaking.
