Sport Scout Racers! Part 2: Tanks  
By Jim Wall
 
 
Carrying on from last week's general overview of Jim's two Sport Scout racers, here's a look at the tanks. Jim has genuine factory racing tanks, and we thought you'd like a peek at these, but if you're building a Scout Racer of your own, "street" tanks can of course be used (oh, one thing; there's a lot of pictures on this page, so you might want to go make coffee or something while it loads). Over to Jim:
 
The tank on the left was a repro from Arizona, notice it is equipped with a quad oil fitting. The original factory racing tank on the right had the quad fitting cut up and only 3 of the 4 holes used. Also notice they're in a row.
The original racing tanks where a lot of work for the factory. They took a normal tank shell and narrowed it. This shot shows the right hand tank and how the normal locations for the gas and oil necks where blanked off. The 1/2 mile bike used all oil in the right tank for he most part. One clever tuner I know of put the oil partition back in the right tank, he however did not put the second filler neck back in and ran a hose from one tank to another thus having a "hidden" gas reserve. Bet that one had people scratching their heads.
In this shot you can see where the indentation for the speedometer was eliminated. At the bottom of the gas tank back you can also see the reinforcement used on the1948 and up fuel tanks. The same thing was done to the fuel tank side also.
Here we see the completed tanks on the Big Base chassis, pretty narrow and neat looking huh? These tanks where in a nasty accident. The right hand tank had big crease near the top rear of it and the left hand tank had a dent in the front where the forks had been pushed back into them. I would hate to have been riding the bike when it happened

Then Jim wrote me: "I also have a set of the junior Scout factory half mile tanks with the backs off, they are really neat. Should I send photos of them?" Well, what would my answer to that be? -Yeah right, here they are! Moen.
 
Here is a view of the left hand Junior Scout tank with the back off. This tank was modified by the factory. It has Sport Scout mounting plates rather than a Junior Scout type which was the same as the 741 mounting plates.
The right hand tank with the back off. Unfortunately it had a mouse nest in it and will need some brass mesh soldered in to fix it.
A comparision of the mounting plates. You can see where the tin was drilled for Junior plates and then drilled for Sport plates.
Even the rear mounting plate was different.  
  
  
  
 
This shot shows the large diameter of the fitting for the fuel shut off valve.
A photo of the patch panel where the fitting for the ignition coil used to be.
A photo of the right hand tank showing how it has been converted for oil only. This whole area is a lot different from a regular Junior tank.  
  
 
And just one more shot of the Big Base racer, as it's so darn neat! Moen.
