Agreed, guys let's get real here. A Yamaha is not going to run like this over that minor of an adjustment. This bike will stall when set at a normal idle speed! The intake sensor as explained previously is good in my book. I will check spark plugs this weekend and as usual post results.

UPDATE: While waiting for my carbtune II to ship, I threw in some fuel injector cleaner and a tank of 110 octane fuel. :p I went riding for about 3 hours and turned the idle up a little. The bike really ran good, almost no surging idle at red lights. I thought I had found my solution! When I...

Thats actually a really good idea and I will try it this weekend. If not I was going to pull the coil packs/plugs to see if there are any clues. Next step is to a different dealer and ask for a diagnosis. I'm getting worried its something expensive like a bad ECU. :surrender: I will update as...

Thank you for the replies guys. Maybe I'll buy the sync tool since I know the FZ1 is the bike I want for a while even if it is not THIS bike. What are the chances this is something major? Should I trade it in for what I paid for it?

Videos Here are the VIDS. I post them in the order they were taken. Very cold start. Hasn't run in a couple days and its raining outside. Around 40F in the garage. Idle is set where dealer left it. Can hear quick minor RPM changes. Running good though. cold_zps94f0ced4.mp4 Video by...

I have NO codes or check engine lights being thrown. To rule out bad gas as the stealership has determined it to be, I ran it down to near fumes and filled it up with 93 octane. Problem still exists and when I lower the idle it exponentially gets worse. Using car experience I would think if it...

Stealership said it passed a vacuum leak test and the bike runs great at higher Rpms. I ran it for over an hour on the highway at 5k rpms no issues. Also when I lower the idle below 1500rpms the problem comes back so I'm not sure what it worse a high idle or the issue itself.

Hey guys just bought a used 2011 FZ1 in January with 600 miles. Has a yoshi slip on exhaust and no other mods to my knowledge. Around 1200 miles the bike started rough idle when warm. It would shake between 600-1200 rpms rapidly. After some searching all I could find was stuff for gen I...
