Suzuki DT75. 1994

Three things happened at once:<br />1-RPM gauge quit<br />2-Engine speed is greatly reduced<br />3-Idles rough<br /><br />engine runs smooth and cranks instantly. Ful throttle only produces half speed and gas usage is greatly increased.<br /><br />Thanks,

Sounds like you are running on 2 of 3 cylinders. Start pulling spark plug wires 1 at a time (best to ground the loose plug wire) and see which cylinder isn't working.

Will do. However, I wonder what made the RPM gauge go out at the same time.<br /><br />sure appreciate your response.

Do a search on these forums for tach problems. Electrics aren't my forte but I believe I have read similar problems with tachs in other posts. I'm guessing an electrical connection and/or part that may be tied in with your ignition. After all the tach is monitoring your ignition and if something craps out in the ignition I suppose its could affect the tach.
