'03 636 never starts on first try!!

(1) It's normal... mine sometimes takes 2 or even 3 attempts... don't see it being such a big deal.

(2) "Sub-par FI system"???? Good lord, it's anything BUT sub-par! The FI system on the '03's is likely the best of the class! I think you're being a little harsh. FI has to do a lot more with throttle response than it does with starting in terms of how it rates. I find the '03 636 is pretty near flawless from idle to redline under heavy or light inputs.

I had the same problem with my bike. The idle speed came a bit too low. Warm up the engine, and then set the idle speed to 1,300 ± 50 rpm.
Ok, I've heard of one or two other guys with this problem...I assume it has something to do with the sub-par FI system on the new 636's. Whenever I start my bike for the first time of the day...and I mean EVERY first time, it never starts. It takes 3 or 4 cranks. And yes I reposition the "choke" to the full back position before starting, full front, middle...I've tried everything...do I have a defect? Any ideas? Thanks bro's.

I must be lucky, mine starts on the first try every time:D
Are you referring to the first start of the day, or every time you start the bike?
Are you talking about the first time you try cranking the bike over, or are you talking about the very first revolution of the motor on the first try of the day.

If its the later, you expect way too much from ANY vehicle. No engine on the face of the earth will start on the first revolution during a cold start.


I didn't do it, I swear.
And even if I did, what makes you think I would admit it to you?
Mine does the same thing.
Won't start on the 1st attempt of the day, always starts on the 2nd. I don't feel it's a big deal, as once those 2 lines on the temp gauge go away, it's ready to scream.
lol, no, I obviously didnt expect the bike to crank on the first turnover of the day...it takes 3 or 4 full cranks before it starts, regardless of where the choke is. If it doesnt have anything to do with the firing of fuel, then I would guess it has to be my spark plugs. I'll check them out when I get a chance.

If you're referring to how on the first start of the day having it start and run for a second and then die, and have to do that a couple times before it'll actually stay started, then yes, my bike does that exact same thing. I think they just need to get some miles on them to get over that. Maybe a PCIII would help by richening up the bottom end a bit

Don't I feel lucky? My '96 starts on the first try every time, whether it's cold or hot :D
