Closing the throttle

[Viirin]

I didn't know whether to post this in "general" or "troubleshooting" because i don't know if it's a true problem

When you guys close your throttle to use the engine to slow down do you get much/any backfire?
I get some but i always have so i never really thought of it as anything other than normal but i figured it couldn't hurt to ask

Thanks for any replies
