Reply To: GT250 EFI DSpec Stalls at Idle after Warm Up
Hi,
Regretfully I have not solved the issue yet but given that I have another bike I can use I have not really been trying anyway.
Having said that, just last week I made another attempt as follows. I installed the tank temporarily about 200mm higher, removed the air cleaner and reconnected the tank with a longer pipe to the injectors. The 2 pipes from the carbs leading to the ISC were disconnected from the ISC side. When I started the bike in this condition, initially I noted that sometimes combustion was taking place under the carb 2 throttle. Eventually this disappeared but I was still getting some misses from the engine which coincided with back pressure coming out of cylinder 2 pipe. The only conclusion which comes to mind is that sometimes the inlet valves were not closing completely. I checked valve gaps but these appeared to be according to specs, right in the middle of the range.
I am currently dismantling the cylinder head to see if I have some issue with valve seating.
I don’t know if this issue is related to the original one but at the moment I have no further leads.
I am still interested in getting to the bottom of this problem and, if ok with you, I would like to collaborate with you to arrive at a solution.
In the meantime can you tell me from where you have sourced the coils and also how you intend to diagnose the temperature sensor?
Regards
joe
