bs 34

BS-34's off an 80SG. So... I ordered a pair of 135 mains from Partzilla... .... received these.... They are identical to the 135 air jet and smaller than the mains....... They will in fact.... fit into the hole for the main...... So, my question is, will they work as mains or did...

Mikes has these.... link to Mikes Carburetor Kit - XS650 - 1980-1984 - Premium Heiden Dyno Tune Converts the fixed BS34 needles to adjustable. Anyone here tried these... have any experience with em.... comments?

Hi, today I just put velocity stacks to my carbs. I also put 140 main jets, 2,5 turn mixture screw. The problem is - when I run faster with wide open throttle, engine sounds like it has no power, fuel and slowly shut down that I need to run engine again. Should I put bigger main jets? Maybe 150...

Pilot screw badly stuck in my LH carb ended up with the threads destroyed and pilot still in there. Need a replacement LH carb body, or would consider full carb or set of carbs. BS34 style, my bike is a 1980 but I believe its the same carbs '80-'84. Let me know what you've got. Thanks!
