Hi today the wind took my bike over when i was at work. it started up just fine but the tach is idling at 6000 rpm and wont go any lower. i took apart the dash and nothing looks disconnected. i noticed the fuel run off had a split a little at the bottom but dont think it can cause this type of problem. what could cause the tach to do this?
thanks john

Look at the cables (choke or throttle, depending the side it hit) for binding or other damage.
it fell on the throttle side and the clip ons pushed up against the tach. my tach is electric and all the cables are good? it idles normally but its saying that idle is 6000???
When the bike is off where is the tach needle?
it sits at the 3000 to 3500rpm spot. the clip on rotated and was pinned against the side of the tach. the tach was already banged up from the po but worked just fine before. you think it did something to the electrical board?
Not really familiar with the inside of the tach, but the needle must be off location. There might be a return spring that is not working correctly.
is that spring inside the tach?
yes
oh great. ill try and take it apart...

Do a search for the gauge face tutorial. It has a lot of good images of the inside of the gauges and a good discussion on how to take them apart and put them back together without hurting anything.

Searched "gauge face tutorial"... Only came up with this thread : (
Here's a how to I wrote to someone...figured it would be good to post it instead of typing it twice....
Here's a basic how to... (read it a few times before you start the job)
You'll need (assuming you have your gauges off the bike): A smallish flat blade screwdriver, two or three small phillips head screwdrivers (1's 2's and maybe a small one from a jewelers screwdriver set ( inexpensive..) for the speedo knob, two small spoons, glass cleaner -soft lint free rag/cloth . An exacto knife and your choice of Orange model paint and a small artists brush for the needles (White needles on white face gauges....bad idea). I used the stuff they use on the RC cars. And some isopropyl alcohol (Optional). A small hammer and a small finishing nail.
After you remove your gauges from the bike... Take a small flat blade screwdriver and you slowly peel the gauge glass bezel open ( slow and somewhat tedious but just work yor way around the whole bezel...)..
After you get the glass bezel off the gauge...on the back of the gauge bucket are two screws that hold the gauge in the housing... remove them and slide the gauge assembly out.(The speedometer trip meter knob has to come off to get the gauges off the bike so it's likely offalready........very small philips head...)
Gently lift the needle over the little pin and let it stop where it stops on its own... On the very outside edge of the gauge Face ( The thin edge not the actual face...) make a mark where the needle sits with a sharpie or something that wont come off easily from handling the gauge face. You do this so you know you pu tthe needle back on in the right place later.
Take two small spoons...and under each side of the needle center -the round part- carefully pry the needle up and off the gauge. Remove the two screws that hold the gauge face on and take the gauge face off. You can paint the white part fo the needle now or or actually leave it onthe gauge while yo do it ( the gauge holds it for you so doing it before you take it off works well...)
For the needle stop/rest... from the back of the gauge face..(with a small socket sitting on the table under the gauge face with the pin pointing down . Take your small hammer and finishing nail ( can use a pointy drywall type screw in a pinch..) careful tap the pin out. The plastic is pretty durable- just take yor time...
Ok.. if you haven't been doing this the whole time...put all your small parts ina cup or something that will keep you from losing them.....
Now cut on the dotted line of the gauge overlays... Take your glass cleaner and clean the face of the original gauge... NOTE: at this point if you want a really bright glowing gauge-you can remove the original face material ( soak it in isopropyl alcohol for a minute or so and rub off the paint.. or use 320 grit sandpaper if the alchohol has no effect)
Apply the overlay (self adhesive just peel the backing off...) carefully making sure you line up the new overlay over original marks ( You basically get one shot at this...but it's not very hard..).
Once you have the new overlays on the faces- take your Exacto knife and cut out the holes on the gauge (be careful and neat ..). Now reinstall the needle rest/pin... This can be annoying - I take a small flat blade scewdriver (say from the jewelers set and push down on the base on one side of the pin and use my thumbnail on the other side to get it started ino the hole... If it doesn't go in all the way that way i turn the gauge face over and let the pin rest on the table squarely and tap on the back of the face right where the pin goes in (just keep an eye on it and keep the pin vertical and the face horizontal as you do it... not too hard). After the needle seats --you may have to tweak the needle into the right position if it's not perpindicular to the gauge face.... no big deal.....
Ok...Now you install the gauge face back onto the gauge assembly with the two screws... Take your needle and reinstall it where it needs to go (remember that mark you made on the edge of the face..).. Press it down- it will bottom out... Gently lift the needle over the rest and let it sit against the rest.... Slide the gauge assembly into the white bucket and reinstall the screws that hold in there.
Take your glass cleaner and clean the new overlay (fingerprints and all...)
Clean the Bezel Glass inside really well while you have the gauge apart!!!
Slide the glass bezel back over the white bucket.... Put the gauge face down on the table ( a soft cloth under it wouldn't hurt) and press the gauge bucket/assembly down into the bezel and take your small screwdriver( a slightly larger one will work too at this point...) and bend the lip of the bezel back around the white bucket. Work your way all around and make the lip as flat as possible after you get it all bent around...( small screwdriver and a hammer..tap tap tap...
Be careful not to scratch up your bezel.....Clean the outside of the glass on the speedo and install the gauges on the bike.
If I can I'll take some pictures on the next set I put together and maybe get a how to page going on this...
Winner winner, chicken dinner! - Bob!
Did you retighten the screws too tight. I did that on a new one and it would wiggle ever so slightly but wouldn't work. Had to get a minuscule bigger screw then had to use two washers for it to make connection! It was a PITA. Scared to take it apart again and of course two months later idiot light blew!

Wow that "how to" is pretty good... :icon_mrgreen:
Ohhh and...
Figure out your Tach problem yet??
