Everything is still original stock......

I have done the same thing - when i got this most recent savage the previous owner just straight piped it and god did it gargle and spit on deceleration and pop at shifting and shutoff..i had to play with it for a bit to get it tolerable for the neighborhood and will likely have to do it again when i install my SE.. but as others have previously posted, i have had no luck getting rid of the shutdown poot.. i have since tuned it to ride right and have kinda come around to the gunshot at the end of my rides Grin

The spacer mod also improved performance in the mid range (pulled a little stronger).

me too,
did the spacer and idle mixture same day, much better performance..

OP: adjust for best running, ignore shutdown "pop" (I like it)

Its sounds like a gun shot on shut down. It runs fine and doesn't grumble on decel. No backfires on shifts...stock pipes....

I put the screw back to where it was factory...starting over...

OK so I did a half turn. Bang on shut down...

Did another half turn...and turned the idle screw back alittle because it was idling fast. No bang. No gurgle no problems... just a dog fart.

Added another 1/4 turn..no bang but gurgles and stuff on decel and shifting..

So I guess I got it. I don't see a difference in how it runs at an idle but it seems more powerful when moving

After I cleaned my carb I put a dyna on, separate weekends, and the after fire has since gone away. I have an 88 so same carb jetting. Now all I get is a very mild dog "ruff" on shutdown.
