Hi i seam to have a bit of a rev counter problem it seems to be showing higher revs then it is, a quick blip on the throttle and it gos way off the clock,are they adjustable any help please joys of a new tiger,

Hi I had similar probs with my rev counter, check the earth connection on the rev counter mine was better once cleaned but it still had a tendacy to bounce between shifts.
I have since given up with the original unit and fitted a smiths electronic tach which I am very pleased with. The one I have is from the Cobra range . the smiths classic range is more similar to the original apart from a white needle, I think smiths may be able to put in an orange needle if asked.

Hi,

I also have problems that the rev counter indicate to much. The needle itselve is stable but indicates more than it should. Not always the same.

Could this be due to conversion to electronic ignition??
Anyone has experienced this before? What is the cure?

My rev counter is not working yet. The electrician didn't connect it up once we had the engine running. I can't remember if he said it would not work or not read accurately because the ignition is electronic and the tac is set up for a points ign. But it could be changed.
We have people who specialize in instrument repair here, you must over there as well.

The rev counters are current driven (as opposed to voltage driven) and therefore may not work properly with some electronic ignitions.

If your rev counter is reading high but worksOK otherwise (as Paulw's did) then it can be recalibrated.
