Suzuki katana ay 50 problems

[DonLewis]

I have a suzuki katana ay 50 Lc 2004, when i stop at traffic lights and let go off the throttle, it will cut out after a few seconds, even after the bike it warmed up. i have a gianelli sports exhaust which ive read that you should upjet about 10% which im planning to do soon do you think this will solve the problem ? also, it accelerates quickly up to 20 then slows right down , and when going up hill loses all power alltogether and slows down to about 15, would lighter roller weights benifit it and how light would i have to go ?

Clean the jets - had an AY50 as my first ever scooter, everything went wrong with it. If it's fuel injected then good luck

They're proper crappy peds, clean carbs, then up jet by doing plug chops.

Plug should be a coffee brown.
