Motor explosions in decelerating

I've got a Yamaha Virago XV535 year 1993. When the motor is warm and when
i'm decelerating, it's explode and I have difficulties in accelerating and,
espacially in starting again when i'm stopped because the motor is stopping
when i'm accelerating in first speed. I have new spark plugs, a new air
filter. This moto
has few kilometres (13000). It's dangerous: when i'm turning I believe the
engine speed is good but it's suddenly accelerating with an explosion. What
do you thinking about this problem?
Thanks.

 

sounds like it is running lean

maybe a case of blockages in the carb

try using some choke when warm and see if it gets any better

 

It sounds like you might need to split the cases.

Hatz, in aus.cars, in gibberish mode

 

Also if it does make it better, even if it doesnt, DONT ride the bike until the problem is fixed, you
can burn a hole in your piston if you keep at it without doing so, i know this through missfortune/
experience. It could be badly tuned, or it could be an airleak between the carbs and their/its boot(s).
Does the engine idle at a really high RPM and slowly creep up when running sometimes? if so it
would certainly indicate a leaky carb boot/manifold.

In any case its a good excuse to rebuild the carbs to make sure of things.
