tachometer (engine code) problem

Hello everyone - this past weekend I installed Ivan's jet kit, a full Muzzy exhaust, and an undertail and integrator kit.

After starting the bike up, I noticed that the tach shoots to 7200 rpm back to 0 rpm then back to 7200. It does this off and on while the bike is running or if the key is just turned on. I talked to a mechanic at the dealership and he told me that it was a problem code in the engine.

Can someone please look this up if you have a manual for the bike? Any help would be greatly appreciated!!!! I would rather fix the problem myself than pay $65 an hour for someone at the dealership to fix it.

EXUP Error code, it's in your owners manual. Just loop the exup servo motor and it'll be fine.
What do you mean by "looping" the motor? I took the whole damn thing off of the bike. OOOPS!!! Still have it though. Thanks for your help droog.:)
Looping means to connect the loose white wire to the black with red stripe wire down at the sevo plug . It is suppose to fix the code problem . It will do the code thing when you start the bike and fine after that . I just looked this up to do myself tonight . I just put my full Akro on a few minutes ago . Got to pull the carbs and drill the air screw plugs now .

You can also fix the problem and not get any codes by putting the exup servo motor back on the bike. I did this with my 98, just take the cables off the motor.:thumbup
