2003 750 - starts from second try only

Yazon · Mar 15, 2008

Hey all,
My 2003 GSXR 750 has issue starting up when not warmed up. Here is what happens

1) turn ignition (can hear pump starting to pump gas and then stop)
2) start the engine - it starts up and died right away
3) start engine again (at this point it runs just fine and sits warming up).

For whatever reason i have to start it up twice every single time. It never starts and keeps running from the first try. On the second start when the engine actually catches - it runs at proper RPMs for cold engine and then drops off a bit to lower idling RPM.

Otherwise the bike and the engine runs like a champ.

Any ideas what's going on and how to fix it? :scratch

check plugs/replace them all
choke or no choke?
battery charged good? is it old?
goos luck and don't worry..its not THAT annoying to have to do it twice

The plugs should be good, I've replaced them not too long ago.

No choke (this is FI ) so the computer should adjust fuel/air ration on start - there is no dedicated choke lever.

Battery is good - never had an issue with it. It cranks fine.

It's not annoying, just kind of embarrassing actually. I keep my bike in top shape - always clean, lubed, and well taken care of. But it never starts from first try as if i abused or neglected it.

As i said - On initial start- it catches and fires up, but dies instantly, then right after when i start it again - it catches and runs as if nothing is wrong with it - smooth, proper RPM, no misfiring or rough running. But always takes two attempts.

i got the same bike with the same issue. i've learned to deal with it. on start up if you give a little throttle it'll start and hold. that's my trick but it's like it needs a little gass in there b4 it'll start.

sorry..my 2002 FI has a choke..and SOMETIMES needs it..but since everything is perfect with your bike i don't know what to say to help

That's ok - thanks for suggestions anyway. It rides like a dream, i'm just nitpicking at this issue since i've had it for a while and haven't bothered to look fix it before.

bigwake your 2002 doesnt have a choke its just a fast idle lever. it does the same thing as giving the bike a little throttle.

bigwake · Mar 16, 2008

thanx..i thought it was a choke because the shop i took it to one time said it was a choke haha..well it makes sense that it's a fast idle..i wondered why it worked so well

MrMotoRdr · Mar 17, 2008

My 2k2 600 has the same issue. I imagine you could adjust the fast idle up a little at the throttle body side to compensate, but I just deal with it and give it a little rev when starting.

hahaha, my bike does this religiously!...

I have an 01 same deal:cheers

This is a hugely common standard operating procedure for the (01-03) bikes with the electronic fuel injection. I used to wonder the same thing when it started happening to me. But now I wouldn't know what to do with myself if it started up on the first try. At least it consistently starts on the second attempt!

Takahashi · Aug 7, 2008

oh snap guys, my bike has been starting on the first try the past few days!!!!

....

i'm scared....

When my K1 600 is cold, I always use my fast idle lever.
It always starts right up on the first try. The fast idle
keeps it running at 2500 rpm until it warms up.

I only keep my fast idle on for about 10 seconds or so to get the boy going. Always goes on the first try.
