1100k tacho issues.

[SiBag]

Having odd things happen with tacho on the GSXR 1100 k.

When I hit 9k the needle leaps to show max rpm and then drops to zero and stays their.

Once the ignition is turned off and I restart the bike the tacho comes back to life.

Any ideas..?

If you have a spare tacho, connect that and see if it behaves the same. If so, it's probably something with the wiring feeding the tacho. If not, it's something with the tacho itself. I use an old 600 teapot tacho I know to be good to diagnose faults in this way and it saves a lot of unnecessary faffing and head scratching.

Good plan
