exup rev counter problem

[vicksr1]

i have recently removed my exup valve and stock exhaust system and replaced it with a full race system.my rev counter needle flicks from 0-7 rpm and back all the time.i have tryed putting the servo back on but it still does it.HELP ME PLEASE: how do i get around the problem?

Have you reconnected the wires to the servo properly
If so it should stop the tacho bouncing to 7k
There is also a box called "Sams "(something)cant quite remember but there was some threads on here about it.
Perhaps someone else knows what it is called and where to get them
Good luck mate

Shoot me an e-mail and I will forward you the schematic on how to make your own ex-up eliminator circuit for just a couple of bucks. This is not my design, but was posted a long time ago and forwarded to me. I made two for really cheap - they have worked great so far.
