Post by Tico on 12/14/05 at 14:26:45

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

Is it normal?

My bike has done that nearly every day since I bought it. I believe I was told that making mods to make the engine run richer helps that. I don't know for sure, as I'm planning my engine mods for this coming weekend. But backfiring at various times is part of the fun of the Savage. Adds character.

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

When mine first did it, I thought, "boy - she fits right in with the rest of the family!" Now, I don't really even notice it.

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).

If You don't want to hear an "explosion" and don't want to play with mods, just let the bike idle for about 3-5 seconds before You turn off the ignition.

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.
