Bike popping and farting on accelerating.

I currently own a Hyosung Cruise II, just recently the bike pops and farts when I open her up. Another way to describe it is it sounds like a misfire? But this only happens every so often. The idle speed is at the right rpm and the accelerator and choke cable are ok.

At first I thought it was the choke stuck open, but I checked it and its fine.

Any ideas?

Leak on the air box rubbers?

Check the spark plug, when i first got my wheels it used to do that in the rain. Changed the spark and haypresto SORTED.

Mine tends to do that as well if i run standard unleaded, but is fine on Super.

Check for water in floatbowl of carb... check that water isn't getting to HT Lead and causing occasional short = no fire = stutter, then suddenly works again = fire = ignites all the fuel waiting in there = bang (misfire)

sorry to jump on this thread late, I was advised not to use super unleaded? I have a GT125R hyosung with a blueflame exhaust. Can I use superunleaded and will it make any difference?
