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

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 Franck

install a new clutch. make sure chain is properly aligned and lubricated.

check the fuel pump fuse, if getting power then replace fuel pump.

wot about your gear selector ??

remove the chain and check all links are free , check the rear wheel bearings are spinning free and not notchi ! check condition of sprockets teeth not worn !

Main fuse is blown, its under the seat on the + battery wire.

Check rear wheel bearings. Be sure the chain is adjusted and lubricated properly.

Waren clutch and or low oil check oil with engine at running temp also check for metal shavings in your clutch oil

Had great luck with Shorai but you will pay for it.

Clean carburetor idle jet and idle circuit.

94 - 96 only!

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.

You must keep the fuel tank at least half full

buy one from your dealer.

get yourself a workshop manual to do this properly

No the starter relay is seperate ! check all fuses and ignition system connections !
