I started my 06 SX yesterday did the same ol procedure. turn the key watch the gauges, flipped the run switch heard the FI waited til engine light went out and tried to start. She turned over fine but didnt start I tried again same thing. I gave a little gas as I pressed the starter the third time still no go. fourth I got a bang out the muffler then it finally started after giving a little more throttle. The rest of the day it started fine with no problems. It also felt it was running a little rough but seemed to get better as it cooled outside. Does any of this make sense to you guys? Thanks in advance Rob | ||

This happened to me with my 2005 XB12S and of course my first instinct was to give it a little gas as well. Of course during one of these cold start mornings I ended up fouling the plugs. So now... I don't even touch the throttle when starting. I think you backfired after giving it "extra" fuel; more than the motorcycle needed. I would be very careful giving it any gas when starting. Especially when you find out how hard it is to change the rear plug. But yes, it makes sense. | ||

No need to give an FI engine gas to start. | ||

Normally I dont touch the throttle at all and it was in the 70s yesterday also it was in the afternoon that this happened. Could the FI be in trouble? TPS? Just curious obviously not a big deal since she was happy after that. It was just something I was not used to especially after it was sitting for the winter months in a nice warm garage but nothing in the way of winterizing, it started up with the first push of the button. | ||

Mine will do that especially if the temperature swings. 80 when it was parked and 40's in the morning when I go to work. | ||

Don't touch the throttle on start-up. It will usually foul the front plug and kill that cylinder. Just one of those "personality" things. Funny thing is that you could not possibly start my X1 without modulating the throttle. So I jumped on my new XB and fouled it right away. You have to pull the plug and clean it off to get it going again. You are lucky if it fouled and came back on its own. | ||

Mine will do that especially if the temperature swings. 80 when it was parked and 40's in the morning when I go to work. I've experienced that too. After big changes in altitude or temp between rides it takes a while to get straight and run well. Do the steady state 3k rpm run for a few miles and it will usually be OK. More "personality". | ||

I understand not to touch the throttle but if the bike is not starting what are you supposed to do? drain the battery with the starter  Im just looking for an answer to why it would not start in the first place. Again I am not too concerned because there were no problems after this but thought maybe this was just a forewarning of a bigger problem?  | ||

My $.02 for what it's worth considering I'm a mechanically challenged newbie  One of the things I've learned in the last few years is that with fuel injection, when you twist the throttle the engine gets gas first then air vs. a carbed engine that gets air first then fuel. When the the bike is first started (cold) it is already running rich so when you give it the gas the engine gets a very big dose of extra richness which can and often will foul the plugs. Usually the front one. I've had to ever so slightly crack the throttle on mine once to to get her going on a not so warm 17 F degree morning. I let her idle for a good 5-6 minutes to make sure all was well & warm before I took off. If you absolutely must give her some gas to get started be very diligent. (i think that's the right word ) No blipping! Crack the throttle no farther than a hair's width to get her started then leave her alone. If it dies, turn key off then back on & wait for the lights & all that again then try starting again with out touching the throttle. | ||

I've also noticed that it helps to cycle the kill switch (which makes the fuel pump cycle again) after a start / stall. And make sure you wait for the fuel pump to cycle off (pressuring up the system) before thumbing the starter. I spent some time going through my throttle cable tension and idle speed adjustments and it starts smoother without touching the throttle now. I've had it run like it had fouled plugs a couple times, (runs badly at low RPM) and I just rode it hard and it seemed to clear itself up fine after 5 miles or so. Still on the original plugs at 15k+ miles. I should replace them, but can't bring myself to bother when the bike runs well... | ||

When mine is cold I just hold the start button longer, takes a few tries sometimes but I wouldn't worry. Just a cold lump | ||

I've learned the hard way with my carb'd bikes to add some fuel stabilizer (Stabil) if the bike is going to sit longer than a month. No need to incur varnish-like goop in the fuel system if it can be avoided for a couple bucks. Also winter gasoline formulation may have different percentages of the volatile components which help cold starting than the warmer months. So if the volatiles evaporate while sitting for 3 or 4 months, that might explain hard cold starting for some. But a fresh tank of gas should fix that. |
