07 R6 Rough Idle

Here is a link for the video.

Any ideas or suggestions why it's dipping from 1,400rpm - 1,050rpm? I read a few posts that suggest it could be back presser, battery, coils or throttle bodies. I just did a full tune up 600 miles ago changed the plugs, flushed the coolant, changed the brake fluid, checked the air filter, changed the oil and oil filter.

I've also tried to change the fuel map on the PC-V in Throttle 0% from 500rpm - 2,250rpm to Zero, 2, 4, 6 all the way up to 20 w/ no change in the idle. I'm currently running Throttle 0% from 500rpm - 2,250rpm at 12.

Well I put everything back together again and still idles like in the video. I guess next step is to unplug the PC-V and Autotune for poops and giggles. I've been searching the web for the last hour and seen many people have this problem :thumbdown I just find it hard to believe that no one has found a fix since this bike has been out since 2006.

I figured it out finally! I read a post Jamie M(pic posted by Jamie M.) made here about the EXUP and back pressure found here

http://www.r6-forum.com/forums/showthread.php?t=66508

So I went out into my garage and fired up my bike. I then put my hand over half of the exhaust pipe to simulate having the EXUP valve and Walla :boob The bike was idling smooth as silk at 1,300 rpm. So my next question is, will this cause any problems with my bike in the future?

the idle from LO to 104 is going to be rough no matter what, nothing you do will change that.

I saw no problems with your idle in that video. seemed perfectly normal to me with the current mods posted.

Indeed, my Honda F4i did that also while it was warming up. But once my Honda got off fast idle it was rock sold at 1,300 rpm. My Yamaha after it's up to 170°F the idle was still dropping from 1,450 - 1,025 rpm. I've never seen anything like this before. It must be a Yamaha thing cause my Kawasaki and Honda's did not do that after I made exhaust and fuel mods.

If you fast forward to the last minite you will see the bike is at operating temp and still idling like garbage.

I think you people do not even read the posts just the heading cuase the 1st guy asked for my mods when they are listed in my sig. The second guy said to check my coils when I already listed the ohms readings for each coil. You probley only watched the 1st 30secs of my video and jumped to a conculion that it was running fine.

Thx for trying though ;)
