Next time I have some spare time and cash I'm bringing my spare head up to a semi-local guy who does porting, and have him do some magic. I'll bring the cut-away head and the goop, and let him do the best he can.
Pretty crazy that the motor is so gutless. An OHC 4 valve 650cc (or 695) should be able to crank out an honest 50 HP in a moderately tweaked state of tune. From what I hear, you are lucky to get 40 or so Shetland ponies out of one.
I have a Mikuni RS flat slide carb, one of Lance's bump sticks, and a Ryca muffler, so that should help.
Right now I have to finish the wiring and all the mechanical stuff.

I'm glad to hear that you are going to finish it. A few months back it seemed as though you might walk away from it.

He Gary,
Well, I found myself with all 6 bikes in various states of disrepair, so I gave up and bought a new bike.
Went on an 11 day/seven state/2500 mile trip, and the world is a better place.
Now that I have something that runs, I can get back to tending to the wounded. Have too much time and money invested to just walk away.

I understand the multi-bike flail, but I also find that I make better progress when focusing on one till finished, then move on.
I know you know this, but sometimes it can be helpful to have a friendly reminder.
ROCK ON DUDE !   Cool

That is one way to look at it. On the other hand, if you compare it to a v-twin having cylinders of similar displacement, the Savage is right in line with them. An 80 inch Harley is around 60hp stock. Removing one cylinder would leave you with 40 cubic inches and about 30hp. The power to displacement ratio is about the same when viewed in that light.

yup. But you are comparing a pushrod 2 valve motor with a rev limiter set at below 6,000 RPMs and an OHC 4 valve motor.
With your logic, an OHC  valve 1200 cc motor would put out about 50-60 HP.
The Savage motor is def an underachiever.

Word..

It's a lawnmower motor with an oil pump.
From a time when things weren't sophisticated.
The bang for the Buck is okay, marginal,, but okay.
The bikes limitations challenge me. I'm not bored.

Yep, learning to hustle the savage around a corner is great fun , and I don't think I will have a seven foot fall after the high side while I learn.

When your riding a slow bike fast it's like your in slow motion , gives you time to plan/think about your cornering/braking. Still every bit as challenging as a fast bike,you learn to brake less and carry more speed into turns to get a little more coming out and wound up sooner for the straights. When the adrenaline starts flowing and your focused and on a favorite road its a rush. Sure that Yamaha R1 coming up from behind is gonna eat you alive,but I could care less I'm in the zone,focused and I am the fastest bike on the road,I own this road ! Make that R1 work to find a spot to pass, when he passes me at light speed I just giggle,he needs a R1 to pass me on this road cuz I own this road ! Way more fun on a big single,just way more fun.
  It's as simple as watching the vintage singles class racing Manx vs Gold Star it's like a ballet on two wheels and intense racing all at the same time.
What we ride is the essence of motorcycling,primitive Big Singles
In my eyes it just doesn't get any better !

I remember that feeling that our "Manteca Man" was talking about, and it was indeed FUN to force those Fast Movers to work at passing our classic thumper on mountain twisties that we found in the Smoky Mountains around the Dragon, and other such roads...those of us on "The Backline Crew".  It was great fun indeed.  
My hand/eye coordination is not what it was a few short years ago so I no longer play that game, but still relish riding those type of roads, albeit at a bit slower pace.  Even so, it still brings a grin to my face when blessed with a Black Line.

I offer this in memory to a dear friend who was taken much too soon, Oldtimer.

Lancer , When I started the tracker build it in part was built to honor a true friend who also passed far to soon. Big Jim was one of the best riders I know , you could say he taught me how to ride , cuz if you could keep his tail light in sight you were haulin a$$. Not once did I ever get the honor of passing him on the street , but passed him several times on the dirt! What a great friend & mentor I lost. He would love my little tracker , he would be gone all day with it if givin the chance !

Most recent photos of REX











Other than the first photo, which combination of seat/tank do you prefer ?

Black tank is stock steel; grey tank is '60's fiberglass BSA flat track tank.
