Reply To: Where are the IAP sensors? – 2016 GT250R
Hi, it’s been a while since I’ve been able to work again on this bike.
I’ve replaced the regulator rectifier, replaced the tank and fuel pump (old one was leaking due to rust). I did an engine oil change. Battery is new and I have a charger in case it dies or is not used for a while.
First start after a few months, both cylinders start, so that looks fixed, only one was starting before (both exhausts hot at the same rate when starting). Bike cold starts at 2000 rpm and drops down to around 1600 rpm and idles okay. Revs well on neutral with normal throttle response.
I know that I need to get the bike on the road for real world testing. The bike used to struggle revving past 7000 rpm under load. I am eager to test that but there’s two issues. It still has trouble starting. It takes quite some seconds of cranking for it to start, and from what I’ve seen, that eats up and kills the battery, hasn’t killed it so far. I assume because it’s finally charging (14 to under 15 volts on idle) with the new rectifier.
I don’t want to put this bike on the road if it wont start easily. And second issue is I’m still getting code c18. Rear IAP sensor was already replaced with a new one.
So:
1. Hard starts, takes too much cranking, sometimes starts on a few cranks (few seconds) or will crank a lot (which used to kill my battery)
2. Still getting FI light with code C18, IAP sensor was replaced already
I don’t want to get stranded, even close to my house, it’s very heavy for me lol. I want to fix the starting issue before getting it out and test further. I’m slowly learning to work on bikes.
Thanks!
