GSXR 600/750 cold start ((my overview & possible solutions)).

Hello folks,



I was recently busy on my job, life and important stuff --- and couldn't write down here how I was dealing with my bike issues.


GSXR-600 K6, always serviced and broken-in by dealer. never been raced\\wheelies etc..



Basically there are 2 main problems I encountered @ 11000 miles.

1. Charging System problems such as fried rectifier/wiring/etc..
2. Cold Start problem (motor dies after few seconds and hard to start without throttle && smelly exhaust cuz running rich && different temperature ~ extra after restart).




Firstly I will start with the charging problems, it started @ 9000 miles with sudden empty battery ..

there was no charging voltage while bike is idling, and stator was fine. . but the rectifier seemed to be dead.


I changed the R/R and the bike went sweet for extra hunderd mile. But the bike died and turned out there was the charging problem again.


Turned out the stator failed this time, I pulled out the stator and it was overhaul((2 windings were completly fried)).


So I got new stator and R/R.



Finally, cold starting problems started on my bike when I adjusted the idle speed, when I got it back to ~1350 rpms it seemed to solve the problem.


But after few days the cold start problem appeared again!.. I used seafoam and the problem z gone!.


Now I'm scracthing my head wondering what's going on!!


could it be my spark plugs?? I just changed them last month.


I hope that you guys share some ideas about these problems..

It's 2006 model,


Do you mean Throttle Body Sync??


I would try to Sync it now and see if it helps.

Just wanna say that I tested my charging system as follows:

idle voltage: 14.0-14.66 V.
Load voltage: 14.6-14.9 V.
Battery voltage: 12.59 V.
Radiator-On voltage: 12.6 V

I tried this test also:


running idle, pressing horn with all turning signals on.. the horn sounded weird " like low voltage " while turning signals were on.

is that normal?


Cheers.

I just had this cold start problem today. I got off work at 1:30 this afternoon and it was about 70 outside. I started the bike and it was struggling to stay running then died. I tried starting it again and it took a few rotations and fired up but I had to give light throttle to keep it running. It smelled real rich but a little oil smell also.
I am kind of irritated because I just bought the bike last month and this is the 2nd problem.

I will wait to see what some of the guru's have to say about this problem.
