Hey guys, I'm new here. I'm in the middle of a project bike. It's my second savage and the first one that i really got this far into. I'm going with a velocity stack or small filter and wanted to run it with just a header or maybe a shorter pipe. I have heard stories of people burning up valves with short exhausts and don't need that extra expense on this one. Any thoughts on that? Also, will I need to rejet and anythoughts on what it needs to be rejetted to? Thanks.

What about a little cone filter or velocity stack with the harley muffler? Does that seem like a good option? I just wanted to get rid of the big air box and bazooka of a muffler they put on these things. Thanks for the advice.

Yes, that can work very well...
If you are at, or near, sea level elevation, you should re-jet with that set-up.
Going up one or two steps richer.
I'd start with a 152.5/ 55# main/pilot and do the 2/3rd spacer mod.
You'll be safe from burning valves with that, at the least.  
The pilot jet will affect your gas mileage the most, so I try to go very slightly lean on that one.  If you want to keep good mpg's you can try staying with the stock 52.5# pilot jet and see how it runs for you.  If you need to go more than 3 turns out on the idle mix screw to get the smoothest idle, then go up one step on the pilot.

To test the main, accelerate from 30 or 40 mph, in 4th or 5th gear at full throttle for several seconds, then reduce throttle by about 1/8,...if power increases for a second, you are lean on the main jet.  Go up one jet size and test again.

A good indicator of overall jetting is the weather...if popping/backfiring increases on humid days, or at higher elevation, that indicates rich....less popping at those times indicates lean.
