      Anyone run a Tilly on their 125 shifter? What was your experience? i have a manifold made up for my IBEA L3 to fit on a YZ125 (’01) but am unsure if that’s a good move or not….Looking to tune needles on the fly.

      Was considering putting it on my winged outlaw, which usually is one gear, maybe 2 on the start… For the sprint kart I’d leave the stock mx style carby… :)

      It will work very well in that application. However, dual carbs will work waaaaay better:)

      Yes Ted,

      I run a Tilly HW 12 34mm Carb on one of my Honda CR125s and a Mikuni SNB 38mm on my other Honda CR125 shifter.

      Both carbs perform very well with the smaller Tilly doing a better job on short tracks and the bigger Mikuni doing a better job on long tracks as would be expected !

      Or for another take on “ON THE FLY CARB AJUSTING” look at my utube here :

      Tilly 34mm HW 12 Carb

      Mikuni SNB 38mm Carb

      UPDATE :

      FYI Shifter Go Kart Guys,

      For the open/modified
      class of Honda CR125 Shifters.

      The very short fuel path direct fit Honda CR125 Shifter intake manifold for 38mm 2 flange bolt types of carburetors is all done .

      It has a 11 degree right rotation angle
      to to clear the kick start bump ( Carbs like the externally adjustable Mikuni 38mm Carbs work really well )

      No more rubber boots with right angle turns to disturb the fuel flow !

      And even a more perfect fit when used in conjunction with the V-Force 3 Reed Cage box .

      I’m getting this experimental test carb fitted up to the CR125 Honda.

      Mikuni Super Butterfly Type SBN38mm Diaphragm Pump Carburetor
      No jets to change ever (well almost never) as it has easy to get to externally adjustable low & high speed mixture screws just like the Vortex RoK-tt carb only a much bigger bore (38mm) to fit the CR125 Honda engine and the fuel pump is built right in too.

      I’m getting tired of always taking off the carb to change the high & low speed pilot jets and I don’t care for float types of carbs either.

      These are one of the best performing and easy tuning carburators that money can buy.

      see below:

      Thank You
