Do I need my carbs re-balanced?

I've just put a K&N air filter in the bike, carbs were balanced like a month ago, maybe two at the outside, power delivery is now as smooth as a babys bum so reluctant to change anything just thought i'd ask the gurus here if I should or not.

You mean it's running? And you're actually riding? DONT FARKEN TOUCH IT.

Carb balance isn't affected by air filter- jetting is though.

Wow!
Mick is riding again!
Bloody hell I was expecting a post from Mick in 2014 --------"FS 99 ZX9 - classic, garaged for past 6 years"
No carb synch is required Mick - but should still be performed during any service. Jetting? don't bother opening that can of worms! If it works then just shut up and enjoy it.........Finally!

Yeah it works, been working for a while now, slapped the other CDI in and all good Fanging around Gippsland for 4 days next week so confident enoug the bastard will start now

thats great news Mick, I bet you are a lot happier with the 9 now eh ??? just a fucked CDI ?

as far as the carbs go.......If It Ain't Broke - Don't Fix It !
