260 & 261 - Serial Side Draft Salvation

I just came across another pair of Riley Racing Carbs. These are a matched set of early style castings without the main jet air bleed between the floatbowl and throat. Note how they're stamped 1 and 2 at top of floatbowls and throats, I'd guess it's for time saving while wrenching/tuning during racing - pretty cool.

And unlike most Riley carbs the idle circuits on these carbs were never drilled out for alcohol, they even had the same size main jets and idle tubes as I was planning to use!

Matching serial numbers, now that's so radical it almost scares me, it's a sign for sure - but I have no idea of what? ...I wish I knew. Now they just need a few things, like a good cleaning and a Knucklehead motor - well, don't we all?

  1. Total mindblower! Lookin forward to see them on that beast.

  2. Did you see the pics of that old Knuckle dragster at Jeff Deckers blog posted a couple of days ago, fitted with the same sort of carbs.


  3. Thanx for tip, I just checked it out. The Tramp is one of my all time favorite bikes.

    Looking at Jeff's photo I see the carbs they used are different castings, the front carb is a late style with air bleed between the floatbowl and throat.
    And the rear carb is an early casting without the air bleed, and they also put the late style notched floatbowl cover on the early carb...
