Dear All,

Please asist me in the following issue with my Himalayan 411 2023 (Last Euro 5 model)

When engine is cold at 18 Celcius ambient temp the bike starts immediately and then dies after 2,5 minutes idling then re-starts without any problem
and keep idling without stalling again.

When engine is colder at 12-15 Celcius ambient temp the bike starts immediately and then dies after 3,5 to 4 minutes idling then re-starts without any problem
and keep idling without stalling again.

If you start riding when engine is cold after 1-1,5 minutes idling, the engine will die after about 30-40 seconds and when re-start again there will be no further
issues.

My Bike has:
Hitchcock's Decat pipe
Red Rooster free flow exhaust
DNA air filter with DNA intake ring
Powertronics V4 (No values added below 1600 rpm)
Fuel X pro (Set to 8)
Kent camshaft
NGK Iridium plug
Hitchcock's performance intake and exhaust valves (Set to 0.08mm Inlet and 0.15mm Exhaust)
Motul 300V 15W50 oil

Best Regards
Savvas
 
Various options come to mind. here is one:
I had the same problem with my BS6 and a similar configuration except it had a 477 engine.
This and other problems disappeared when a mechanic discovered the PT4 and FuelxPro has been wrongly connected. At the time I did not even think that would be possible but it was. A video conference with Racedynamics support via whatsapp cleared up the problem after which the bike ran much better (and no more stalling).
To check your situation I suggest you disconnect the PT4 and Fuelx, look if the problem persist, if not re-connect only the fuelx - check again and if the problem is still absent you found the culprit.
because you do not run a BB kit there is no issue with using the oem ECU.
