or is it some thing else?
Any ideas, Mick

Hi Mick,

Welcome to the Savage world. It is a fun bike. I am a former BSA Goldstar (DBD 500) rider and had an instant like for the Savage because it is a big single, although the performance is not on par with the Goldstar. You can improve the Savage a good bit with carb, exhaust & cam mod's for more usable power. The suspension, brakes and seat also need attention but that is another story.
Back to your backfiring. It results from the very lean carb jetting, particularly the pilot jet. There are many discussions on this site about removing the plug covering the pilot jet adjusting screw. Do that if it has not been done already. Depending on whether you have the stock exhaust or not, adjusting the screw for a richer mix may stop the backfiring. Turn it out no more than 3 turns. Once you get past 2 turns out, you should start considering going to the next larger pilot jet.

Over 800 miles with no backfiring. I installed the Dyno-Jet kit for the S40 and it works like a dream. The bike runs the way it should have from the factory. It comes with an adjustable needle and different main jets incase you are running a aftermarket exhaust. And very good instructions.
