    '03 Tuono tachometer problem - Help!

    I finally got the wrecked Tuono I bought two months ago,.......Anyway, everything on the instrument cluster seems to work just fine except that the tach's "rest/off" position (what it indicates when the bike is off) is about 7000rpm. The bike idles at around 8000 (indicated) and responds normally to the engine speed. Is there some "reset" or secret button pushing sequence that will fix it? Thanks in advance for any help!

    The needle just lightly pushes onto the shaft & a good BUMP can move them. Yes ! I bumped mine ages ago when I was in there doing an up-grade, & it wasn't until I closed it all back up that I noticed mine had moved on the shaft .
    It may just be this if you are lucky. But be gentle with everything in there if u open her up.

    Tach problems

    Did you ever figure out the source of your tach problem? Mine is doing the same and nothing has ever touched my needle. What city in TN do you live in?

    And mine reads about 1,500 too low. Have to dig on in there and change a few lights that are out, too.

    And at only 86,000 miles. What a POS!!

    My Tach recently started reading about 1.5k below (after I gave her a bath). I was hoping it wasn't electrical. You think it's as simple as a big bump (or bumps) moving it?

    tach reading incorrect

    I had some starting issue were the electricals seemed dead, but the tach needle "vibrated" at 11K rpm or so with the key on. I took the battery out found it was charged, put it back in the next day and it started right up. Now the tach idles at about 4500 rpm and revs fine up past 11K, weird! it seems the needle has jumped up about 3500 rpm. All else is fine now. I plan to replace the soleniod, battery and possibly the rectifier with the suggested Yamaha parts. How do you fix the Tach?

    Thanks in advance, I love this bike and have put about 3K miles on it since July.

    Sheesh, rap that sucker out, see if you can get 14k RPM - that'll get you over 200MPH, easy. SWEET!
