CV Carb Y74A GC25...27038-92
« on: February 09, 2018, 04:52:54 PM »
 I am a recent EVO purchaser and I got a 1992 FXRS...The original carb on the bike is worn on the needle seat posts so the seat does not always stop fuel overflow. I bought a really nice take off at the swapmeet ..it has Y74AGC25 stamped and the stick on tag reads 27038-92...I am trying to find out what this carb came on stock..Big Twin or Sportster??? I would like some feed back on this if you fellas could enlighten me on this subject matter....

FYI, I have fixed a couple of CV's that had the same problem, float pivot bracket worn out. All I did was drill out the holes in the pivot towers, and use a piece of drill rod for a new float pivot pin...

 I've done the above lots of times, I also use a pencil eraser head turned to a cone and polish the seat with toothpaste or the like. Sometimes there are  small nicks on the seat & use a fresh needle.

I do agree with Jeff & JW. Another thing to think about is a bad float or just out of adjustment. You do have to adjust the float height with the carb at 18 degrees, just cut yourself a wedge of wood at 18 for that.

Reminds me way back when with old Triumph's . Learned fast to shut the valve off  1/2 block from home . Fast fix for leaky carbs ,. Came stock from the factory that way back in the day.
