Replace carb slides. Order the parts from hyo dealer. Remove carbs. Take out old slides and replace with new ones

SOURCE: my rev counter does not work on my kawasaki er5 1999

The ER5 has got an electronic rev-counter, no cable.

Like the oval rear brake-drums this is another ER5 bugbear, the rec/rec fails, the battery boils and the rev-counter is usually a victim too.
Often on ER5 specific forums there will be someone who repairs the circuit board and sells the repaired units much cheaper than a new one. it's usually a tiny zener-diode that is killed.

SOURCE: How do I derestrict my 2006 Kawasaki ER5 please?

I assume it has been restricted to 33bhp for use on an A1 license?

If so it will either have been done through the ECU if your bike is fuel injected. Or (more likely) it is carbs then there will be large washers inside the inlet rubbers restricting the bore of the carbs. If you take the carbs off and pull these out you'll have access to your bikes full potential.
