Do you have this startup behavior?

Hi, I have a new 2013 and I have had this startup behavior since new. The bike seems a bit cold natured upon startup. The first few revolutions after I let go of the starter it sort of chugs and spits a bit and the FI light stays on until it picks up and takes off. Bike was completely stock with this behavior and the Idle is adjusted properly. Also I know its cold outside but the bike is sitting in my garage which stays in the low 50's. This only lasts for a second or so then it kicks in. Sometimes it actually dies the first time but then always starts on the second attempt. It was worse the first couple of startups, but now with 75 hard miles on the bike its a bit better but not completely gone.

Just wondering if this bike is just "like that" or if maybe since I got a new old stock its possible something got clogged up over time from sitting. I do know the bike had not been prepped when I got it so it shouldn't have been dirty gas or anything like that. Also I added a CAI yesterday and that did not seem to help the issue. Power and full throttle runs seem to be ok, its not starving for fuel. I have never ridden any other 900 so I don't really have a comparison.

Hi.
Do you mean the bike has only done 75 miles? If so i hope you are not really riding it hard yet !!!!
I would guess that when you give it a fill of good fresh gas ang get another 100 miles or so it will all come good. In all probabilty you are using gas contamiated with at least some old fuel. Enjoy the bike and give it a long gentle run asap

Dark Archer,
Is this the same bike that you have put the intake mod on?

Yes but it had this issue completely stock. The issue I am describing is the stock behavior. I have only started it up once since the mod and the behavior is exactly the same. Yes I only have 75 miles on the bike. I broke this bike in using the motorman method of a hard break in. So although its not completely broken in, I drive it as such. I ran all my previous bikes in soft, and just wanted to try something different.

I'm not normally defensive, but its a choice I made to try and I don't really see why everyone is so against it. The only person telling you to run it in easy is a company who has to worry about product image, and potential lawsuits.

The people who say run it in hard build and work on engines for a living and at least in the case of motorman are attempting to provide truth that their method is superior. Do understand a "hard" break in is not a "mistreat your engine" break in. Its fully warming the engine then gently rolling on the throttle to create pressure on the rings both while accelerating and decelerating. Both methods call for varying speed, and why do you think that is? To seat the rings by creating that pressure. Motoman is simply implying it takes a bit more force to seat those rings properly.

Also take a look at the 3 common forms of break in. Race track, dyno, and street. Do you notice anything about the other two? Do you think anyone on a dyno or the race track will be taking it easy?

I personally cant prove that either method is superior. Just because I have always used the easy break in and my bikes have been "fine" doesn't mean that I am not willing to try something different to get a better result. Hell I have used the H&R block software to do my taxes the last 5 years. This year I tried Turbo tax and its cheaper and I like it better. You never know until you try something.

I fully expect I will not see any different result with this bike than the last two I broke in easy. In that case I will have still won because I will not have wasted 1500 miles of my life watching the RPM gauge and trying to remember when to shift.

For what it's worth mine might take a couple of hits on the starter but once it kicks there is no splutter or anything. Goes straight into fast idle. Yours doesn't sound right.

When "cold" my 2012 (4,600 miles) jumps right into fast idle after about one second on the starter. I've always been very pleased with the way this bike starts.

It's freedom brother do what you want - but to post about a starting problem after reading you did some mods in another post - it just doesn't make sense to me - but that's ok it doesn't have to.

As an update (not sure why I didn't think of this before) I searched YouTube and watched several V900 startup videos. You could tell most of the guys "pre warmed" the engine but I found a few cold starts and they behaved similar to mine. You hit the starter, let go, then there is the half to one second slow chugging during which time the FI light stays on, then it kicks right into fast idle. After seeing at least 3 bikes do this on YouTube, one of which I was 100% sure was exactly like mine because I could see the FI light and everything, I am writing this off as normal unless it gets worse or something.

SC900LT I totally hear what your saying. I read forums every day where people do the most crazy things or have some sort of warped understanding of how things work. Just last night I was reading about a guy who thought his fuel controller on his V900 needed to be different than everyone else because he was a physically heavy guy. Someone had the sense to comment back that unless his girth was rolling over and partially blocking the intake, the fueling should be the same.....

Thankfully I have a pretty good handle on how things work (IMO), and I made sure to pay close attention to the issue before and after the one mod I have made so far which is the CAI. I still feel that this IS a fueling issue on startup, but its an issue a lot if not all of us share. I think I may have over exaggerated it to the point people are thinking I have some major problem. Its probably just me getting used to the quirks of a new engine.

Here is a video of the exact issue. This is not my bike. This is a "good" start for my bike.
