When I turn off my bike,  frecuently there“s an exposion and back fire.

Is it normal?

That's a Savage.
Engine is adjusted at a very lean mixture to comply with enviromental requirements.

Look up the various post such as:White spacer, removing the idle mixture plug and adjusting the idle mixture. K&N filter, Sportster exhaust etc.

Happy wrenching

It can be tuned out with some effort. It can be eliminated (according to a lot of people on the forum) with some minor modifications. I don't really think it's necessary, but it is the nature of single cylinder engines. If you don't like it take some time go through the previous posts. Tune the engine (yourself - the amount of time I spent would have been pretty prohibitive costwise if I was paying a mechanic just to eliminate afterfire).

there are about a 1,000 posts on the subject on this board.  you can get rid of it if you really want to (although it doesn't really cause any harm).  just do a search . . . you'll find all the info you need.
