Check some of the 750 threads Bones, I think it means "clean and free up the EXUP Valve". <p><!--EZCODE FONT START--><span style="color:blue;font-family:times new roman;font-size:small;">Genisx1AtYahooeyDotCommaMomma</span><!--EZCODE FONT END--></p><i></i>

thx how hard is that to do I am handy but I am not tech the bike has a V&H SS2R full system and stage 2 jet kit. <p></p><i></i>

I think they may vary between bikes though. On the yzf750 7000 represents something to do with the fuel pump (I had the unfortunate problem of forgetting the ground wire). Does it ever go to zero? Normally the tach codes will fluctuate from zero, to code, to engine speed, then repeat. I can only assume this is true of the yzf600 (it is true on the 750 and 1000)<br><br>On the yzf1000 (page 8-68 of the service manual available on the ftp site) it indicates:<br>3000 - throttle position sensor (disconnected, short circuit, or locked)<br>7000 - exup (disconnected, short circuited, or locked) <br>8000 - fuel light (disconnected)<br><br>Not sure about the yzf600 - is there a service manual available? If so perhaps it has the same sub-section as in the 1000 manual (the section is labelled 'self diagnosis') <p></p><i>Edited by: <A HREF=http://p072.ezboard.com/bexupbrotherhoo ... =bozau>boz au</A> at: 7/5/05 2:51 pm<br></i>

Full system is sans EXUP. Check to see if the EXUP servo is still connected. If not, that my be the problem.<br><br><!--EZCODE QUOTE START--><blockquote><strong><em>Quote:</em></strong><hr>7000 - exup (<!--EZCODE FONT START--><span style="color:red;">disconnected</span><!--EZCODE FONT END-->, short circuited, or locked)<hr></blockquote><!--EZCODE QUOTE END--> <p><!--EZCODE IMAGE START--><img src="http://img.photobucket.com/albums/v209/ ... <!--EZCODE IMAGE END--><br><!--EZCODE ITALIC START--><em><!--EZCODE FONT START--><span style="color:red;font-family:times new roman;font-size:small;">There are some who call me........Tim?</span><!--EZCODE FONT END--><br><!--EZCODE FONT START--><span style="color:white;font-family:times new roman;font-size:small;">Top Speed = Mach 0.197 or so... </span><!--EZCODE FONT END--> <br><!--EZCODE FONT START--><span style="color:blue;font-family:times new roman;font-size:small;">1994 FZR 1000</span><!--EZCODE FONT END--></em><!--EZCODE ITALIC END--> <!--EZCODE IMAGE START--><img src="http://img.photobucket.com/albums/v209/ ... <!--EZCODE IMAGE END--> </p><i></i>

It bounces from 8000 to 5000 to 0 but it will n ot register the rpm <p></p><i></i>

Hi there shouldn't be a exup on the 600.<br>Does your fuel gauge work properly?<br>I had a Yzf600r 97 motor in a fzr400 and the same indication.<br>I believe it was around 7-8 k on the tach.<br>Mike <p></p><i></i>

there isn't a fuel guage on that bike just a light <p></p><i></i>

If it's the same as the 'Ace, it will show 8000 when the low fuel sender is either disconnected or knackered, crying or very sad, or even if the fuel tap is not turned all the way on.<br><br>FT <p></p><i></i>
