just installed new mikuni on my 23.When i hooked up the rev limiter it would not start take the green wire off an leave other wires on an it would start no problem.put green wire back on kills motor right away so does this mean i have a bad rev limiter? or just putting green wire in the wrong spot?

If you dont have the rev limiter hooked up properly it will do that.

When you turn the key switch on do you hear a single click/tapping sound from the rev limiter? If you have the rev limiter hooked up properly, when you turn the key on and then back off you should hear a single "click" coming from it.

yes i did hear the click when the key was turned on.

i hooked the red to cylnoid just before starter an ground black then put green wire to the point where kill switch comes off handle an attaches to motor

Sounds like it is bad but just to be sure, where do you have the 3 wires hooked to?

is this what you are talking about?

You hooked up the red wire incorrectly. The yellow wire coming from the key switch only has power when you turn the key to the "start" position, and does not have any power when you release the key and it goes to the "run" position.........which is why the motor is killing.

What frame do you have? MB, go devil, gator tail? And does it have a clutch?

i have a mud buddy min that had a 14 on it i just put a 23 on it has no clutch

Ok then, on the wire harness coming from the key switch, there is a white wire that has a long (white in color) plug on the end of it which shouldnt be hooked to anything. The white wire is what has power (12volt positive that is) when the key is turned to the run position. Splice the red wire from the rev limiter to the white wire and 1) you should hear a single click from the rev limiter when the key is turned to the run position, and 2) your rev limiter should start working properly.

thank you for the help! i have one more ? please is this were i hook green wire?

Yup.

thank you for your help! I appreciate it.
