gpz 500s misfire

[calmac0]

I have a problem when reducing speed, there is a misfire in the exhaust and when I dip the clutch the engine cuts out. Any advise out there?

Don’t slow down!

Seriously though, it’s probably worth investigating the fuel mix. Could be that jets are blocked, mixture is wrong, air filter is blocked etc. I’d start there.

Yep i agree with imperialdata, it does sound like a fuel problem a misfire (properly called afterfire) is an indication of incorrect mixture (usually weak) carbs need stripping & cleaning properly then setting up to stock spec & balancing, presuming the bike is standard on both intake & exhaust sides this should sort the problem.
