By the V.I.N. number. Write it down and call a dealer or look it up online.

Compression test is read in psi and a leak down test read in % leakage. 20% leakage is not good. with the leak down gauges in place, listen at the carb or end of the exhaust and in the oil fill hole for leaking air. That will tell you if you have a bent valve or broken ring.

check with a squirt of oil down plug hole, then re test see how high it goes then, could be the top ring gone, if this is the case it may need a glaze buster to remove any slight lip that has worn in, or a rebore.

if you smell coolant in the exhaust then the head gasket is most likely blown! That will definately keep it from idling properly.

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

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 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
