I am going to bypass the EVAP and remove the canister as soon as I have some free time on the weekend.
This is exactly the problem. Now I just hope my mechanic is willing to remove this for me.

Trust me, a dealer mechanic will not remove a evap cannister.....it will have to be done by you or someone you know that has the know how to do it.

I meant my local moto mechanic (not dealer).

I'm not saying your local mechanic wont remove it, but it is technically against the law to remove a properly functioning emissions device (I realize its not actually functioning properly because its causing hard starting, but I doubt that the government will see it that way). I dont remember where I saw it (maybe someone on the forum can help me out with this) but there is step by step (with detailed pictures) instructions somewhere on the internet for removing the tank of the FZ-09 to get to the evap canister. It looked simple enough, I plan on doing it myself once I have a free couple of hours.

Just for info, the EVAP canister was full of fuel.
I am on this forum as I am thinking about an FZ-09 for a daily bike, couple of long trips a year and so on. My Panigale never left me stranded due to EVAP, but did delay a lot of rides whilst waiting for it to cool down, 40 minute fuel stops every 90 miles become tedious after a while!
Do you feel this is a huge problem for the 09?
I haven't removed my evap yet, but every indication from what I have read online has lead me to believe that removing the EVAP solves the hard starting problem. I dont want to assume, but Im going to go ahead and assume that only the california FZ-09s have the EVAP because its the only state that requires it by law (I Believe) and it seems to be the only place where people are reporting having this issue. As far as this being an issue that keeps you from buying the bike, It wouldnt keep me from buying an FZ, the FZ is awesome! Are you somewhat handy? if you can remove the tank you can get to the EVAP to reroute the hoses to bypass the canister, it doesnt seem super complicated, as soon as I have some free time, I will do it myself and let you know if there are any tricky parts, but Im not anticipating any.

Scenario - In the morning when I start my bike for work, it will fire right up. (I'm in southern California so at 6am it is about 50 degrees.)

I park my bike in a lot uncovered.

I take my lunch at 12noon,

By this time it is 70-80 degrees outside. I put my key in the ignition, turn to the on position, wait about 5 seconds, then push the start button down. The bike responds with not turning over. I then have to turn the bike off then back on about 2-5 times or so, even having to twist the throttle a little, then the bike will suddenly fire right up.

I'm mentioning the temperatures because I noticed when it is cold outside my bike has no issue starting up, BUT when it is hot outside I get this problem.

It reminds me of when I had a carbureted bike and my carburetors needed to be re synced. I know that my FZ-09 is fuel injected. It makes me un easy to have a 2014 Yamaha that wont start on the first try? Has anyone else had these types of issues?

Thanks,

George L.
it won't fire up until I give it gas at the same time which is horrible for the engine.
