About got it running.
I need an adapter to connect the exhaust to the harley muffler mounted on the oem brace. It looks about 6 inches with a bend needed.
I need a fuel cap. Tank is locked shut. What fits?

I don't know that anyone has ever found a fuel cap from any other bike that will work on the Savage.

Here is the specs for an adapter if you want to build your own.....it doesn't have to be stainless - but it is impossible to keep paint on anything that gets that hot.

The RYCA is chrome, it fits and holds up pretty well.

Thanks on the input.
I found a weld on fuel neck and cap I'll try, maybe. It'll stick up but that goes with the bobber look alright.

Two days ago I fitted a Harley Dyna by cutting the inlet of the Dyna 7/8ths way round with a 1mm cut off disc and rewelding using a stick welder and stainless rods to the Suzuki,s 8 degree offset. I also removed the two knobs inside the inlet of the Dyna using a hole saw and drill.
The original Suzuki clamp will fit on the outside with a short piece of 50mm tube under it .  It is necessary to split this tube  and remove about 5mm to allow it to clamp down properly.
Between the muffler and the header  I used a piece of corrugated tin can as a crush sleeve as has been suggested on here. I also used CRC muffler sealant THe Dyna then bolted straight up very easily  to the original mounts and right up to the ring on the Header
I also refitted the original heat shield using a hose clamp at the rear
through a small custom made bracket at the rear bolt hole.
Easy modification and works and looks good

SavageMan99, I made an adapter using Dave's drawing but made it slightly shorter to help with the fit up of the brackets on the muffler I bought.  I started with a stock exhaust pipe adapter piece I found at a NAPA parts store.  I didn't get a perfect fit on one end and there was a small leak.  I bought some stuff called muffler cement and stuffed it into the joint and it worked very well.
