Motovalet Posted February 28 Posted February 28 Does anybody know why my carbs would be stamped with what appears to be “PBS” and why they would have what appear to be ridiculously small jets at 112 carb number 1 and 4 and 110 for 2 and 3? Quote
davecara Posted March 1 Posted March 1 PBS is probably whoever jetted them, and its common to see different jets on 1 and 4 as those carb bodies tend to be cooler than 2/3 so will fuel slightly differently 1 Quote
manden Posted September 8 Posted September 8 Ok. Got some that was of a track bike. They had a really rich pilot and lean mains to get the top end power Quote
