Reply To: Where are the IAP sensors? – 2016 GT250R
Thank you I’ll replace the oxygen sensors and make sure the ecu plugs and pins are cleaned with compressed air. To clarify, do the O2 sensors actually affect starting or running only, or both?
Regarding the battery, it’s rather new (not exactly premium) but it charges around 14 – 14.5 volts when running. It also does not drop below 10 volts when cranking, stays around 10 and below 11 during crank. Wouldn’t that be enough to run the bike? Or will a more expensive/ premium battery make it start better?
Spark plugs are new, CR8E ones, I checked the grounds and they were okay, fuel pump primes (is new and oem), injectors were cleaned and they fire properly, fresh fuel in the tank, new fuel line and fuel filter, clean airbox, starter relay is also new (oem).
I checked again earlier and sometimes it cranks repeatedly without starting, sometimes it starts with a single push of the starter button. Then idles and revs fine, I will not ride it with fear of it not starting on me.
Should I replace the spark plug caps/ high tension lead with the uprated ngk ones you guys sell on the site? One of the caps uses a thick copper wire as high tension lead (previous owner), I made sure it wasn’t oxidised. The other spark plug cap looks good and has the oem high tension lead.
Sorry for the essay, been like a year I’m fighting with this bike. I’m getting a new suzuki next time lmao.
