the FZR started playing up on track yesterday.

didn't get it back to mine after last TD so battery not charged.

battery was low, by the end of the day had to bump start it but ran.

tickover was a bit lumpy and revs came down slower than i'd expect after blipping throttle.

before one session she fired up but wouldn't rev at all and died if throttle released. next session tick over back to being lumpy.

last session of the day would only rev to 10,000rpm.

will be charging batt and inspecting carbs, any idea what it could be, anything else to try?

I'd go with charging the battery first. After that cleaning the carbs, check the float height. Have a look at the plugs, it's always good to check them, and try a second set if you've got some.

A lot of racers have a battery charger on with the tyre warmers
