How do you correct the Rev Counter?

[irie]

I've done searches but can't find any solutions.

The inj SV650 rev counter is hopelessly optimistic, does anyone know how it can be corrected to show a 'genuine' reading particularly higher up in the rev range?

Maybe the simplest way is to find out how much it's out on a dyno, take the instrument to pieces, and simply move the needle down a bit so that it's reasonably accurate between 8-10k???

I know the speedo is 9% generous, but this is the first I've ever heard of the tach being inaccurate.

Regularly shows over 11,000 rpm without hitting the rev limiter which is of course a fairy story (race bike, standard ECU).

what year is your bike?? ive heard a few slipped through around K3/K4 with either no rev limiter or a higher rev limiter.

So technically thats a kit ECU and worth a fortune :) and NOT cheating under minitwin regs! Where can I get one? :P

I read similar somewhere, think Barwel mentioned it sometime in the past.

Someone will prob know how to check and confirm if this is the case.

Just not me :D

Interesting as my sv (k4) will happily rev abit over 1k more into the red line before the limiter kicks in.

Iries bike is as far removed from a minitwin that you can get on an SV LOL. Irie - you need a race dash!!

It shows over 11,000 on the rev counter when it hits the rev limiter at what the dyno says is 10,200

If I can't zap the stock sh1te rev counter somehow I'll just stick a digital go-kart rev counter on it running off a HT lead. Got one in the garage somewhere.
