rev. victor Posted May 15, 2006 Report Share Posted May 15, 2006 Just pickedd up a 1999 321 TXT. It's my first modern trials ride and have been going through it changing fluids, adjusting, etc. It has the stock Delorto carb. Question is about the two screws on the carb. I know one is mixture one is idle, I just don't know which is which and wanted to find out before playing with them. Didn't get a manual with the bike so any help would be great.

how61 Posted May 15, 2006 Report Share Posted May 15, 2006 Hi, the larger screw with the knurled head and visible spring is your idle screw, the smaller, recessed slotted head screw is your mixture screw, have fun, regards Howard Quote Link to comment Share on other sites More sharing options...
rev. victor Posted May 15, 2006 Author Report Share Posted May 15, 2006 Howard, Thanks, that was my inclination. Most other carbs are like that, but wanted to make certain. What a change from the vintage stuff. Last bike was a Ossa MAR. Night and day. Quote Link to comment Share on other sites More sharing options...
