My tires sizes and gearing are all different than stock - so mph numbers can't be used as a suggestion for shift points.

The Savage single cylinder engine is a low performance design, and it doesn't need to be revved to make power.  The engine makes a lot of torque at low rpm - that is the advantage of a big single cylinder over a multi-cylinder engine.  As you accelerate you can feel the torque begin to drop off in the upper rpm's....and that is the signal that it is time to shift to a lower gear.  

On my rides in the rural roads where I live I ride at speeds between 40-60 mph...the engine is between 3,000 and 4,000 rpm for most of my ride.  I can ride all day and never use more than half throttle, as I find the corners the fun part of the ride and blasting down the straight sections isn't common for me.

Here is a video of MM, Stewmills and I riding the Tail of the Dragon.  It is pretty typical of the rides that I go on, as the roads in Kentucky that I ride are curvy like this but with longer straight sections between curves.  The torque of the Savage engine allows me to ride with very little shifting - really tight curves might require dropping down 1 gear.

When I was in HS, 16-17 years old, I worked all summer to buy my first bike, a new Suzuki 150 2-stroke twin.  3 years later as I prepared to “Go Army” I went to Olathe KS to visit my brother before going active duty, where he told me about this flat track racer that was for sale at a tiny local shop that just opened.  It as an old house with bikes throughout the rooms, no maintenance area, just tinker in place.  Among the interesting collection of bikes were the BSA Goldstar flat tracker and an Indian flathead chopper.  Every bike there looked great.  I took a test drive on the Goldstar, told the dude I wanted it, went to make arrangements, and took it home.  I’ve been a big single fan ever since.
The Goldie cost me $800.
Completely rebuilt exactly at it was raced including the Ceriani forks & 1.5” Amal GP carb, (except for the tank, fiberglass 5 gal road racing tank, silver w/black pin striping). The carb had no idle circuit.
0-110 mph was “Hang On”.

I believe this was a consignment shop, the Goldstar was, and it would account for the excellent variety of bikes he had gathered together.

I’m waiting for it to show up.  It looks pretty good and does have the styling que’s of the original Goldstar, but at 437 lb/470 fueled & 70 mpg, the range is about 180 mi.  BUT, the engine is built by Rotax, 652 cc, 100x83mm, 45 hp @6500 rpm,40.6 lbft torque @ 4000 rpm, with 11.5:1 CR., according to the factory, Brembo brakes, liquid cooling and FI.  A bit on the heavy side but it’s got some muscle to push it around.
Cycle world said it’s good for 100mph, and maybe a bit more if in a hard tuck.  
I’m interested.

I can so appreciate that!!  You’re a good man!  I want to call you friend bro!  Have an amazing evening!

It is very interesting!  I like the old school styling.  The clean power, brakes, and smoothness of a rotax in a thumper!  The mass isn’t bad and would definitely help on 70mph US highways.

Sometimes it's just-tooling-around-shifting.  Other times it's hard-throttle-end-short-shifting.  It might be rev-it-till-it-rattles-shifting another time.  

I guess it just depends on my mood.  I just figured everyone rides with a variety of styles and techniques.

I’ve found the LS650 to be a stable platform, even up to 100mph, assuming everything is working well on the bike.
