cutting lrd, backfiring, and where to buy spark arrestor?

[Martin Blair]

I was wondering if the 400 would benifiet at all from me cutting 2 -3 inches of my lrd to get a little more low end. also where can i get the spark arrestor for the lrd?

And one last thing i cant remeber if backfiring is to rich or to lean, every time i shift it backfires.

Cutting it won't make that much of a difference in power, it will just make it a hell of alot louder.

Backfiring is usually a smptom of lean jetting, but can be due to incorrect timing.

could valve clearence cause backfiring? it sounds like i got a loose adjuster or raocker arm could that cause it to backfire?
