06 hard to/ wont start after warm

[06_RR_KING]

My bike takes a super long time to start up and after its warm if I shut it off to say get gas and try to start it back up it won't start and need push started...but then sometimes it will just start right up. I put the battery on tender for 3 days and the same problem takes a few trust to start. Smells like its running a little rich... only mod I have is a big gun slip which is getting canned asap! Maybe just needs a pcv and a tune?

Slow churning or just multiple reps until it fires?

When/if you find a fix, please post it. I've been struggling with hard hot starting on my track bike ('08 model) for nearly a year. It doesn't pose that much of a problem because it starts fine after it cools for about 20 min and you typically get 40min of downtime between sessions. Things I've tried without success:

spark plugs
clean injectors (Pro-Flow)
change ECU
swap MAP/IAT/CTS IACV sensors
throttle bodies
tank/fuel pump
battery
removed fuel controller

Some of the parts above have been swapped out from my '10 street bike which functions perfectly. Only way I can get it to start hot is to crack the throttle when hitting the starter but still struggles. When it does fire, it will stumble for 20" or so then run fine. I'm fairly convinced it's a flooding issue since it smells rich when it does start but can't find what's causing it.

Good Luck

I like to know the cause as well. I have '06 CBR1000RR

So yours isn't an issue of your battery being drained?

Ya the longer mine sits the better chance it will start right up it pisses me off I have to push start it after I get gas the hell? I'm sure mine needs plugs and all that crap but still my old beat 05 636 ALWAYS started right up even after being slammed in a mud puddle hung upside down on a wrecker and hydro locked and sat for 8 months took 2 seconds to start up

Wow...people are coming out of the woodwork right now to talk about '06/07 starting issues. Why hasn't anyone brought these up before?

I have no idea I'm hoping a major tune up exhaust and tune will help her out next year
