DT360 pilot jet - 50 or 60? was created by msavitt

I was told - assuming I didn’t misunderstand - that proper pilot jet was #50. But manual says 60?

Any help clarifying appreciated

but if the experts, yourself included, say #50 (which is what i found in carb) then I am done!

The pic I posted is straight from the service manual available in the tech library. It's on page 105. What manual are you using? I knew there were plenty of errors in the parts lists but didn't realize there were errors in the service manuals as well. As much as I appreciate you including myself with the experts, I only wish that were true. I've learned a ton since starting my project but still have much to learn, What little I do know I owe to the real experts here.

Service manual in Tech Library has another chart near the beginning... it contradicts the correct chart later on. Quite a few typo's in Yamaha literature.

Parts lists and Original Service Data Sheets show the 60 for the 250 and the 50 for the 360.
1963 YG1-T, 1965 MG1-T, Allstate 250, 1970 CT1b, 1971 R5, 1973 AT3MX, 1974 TS400L, 1975 RD350, 1976 DT175C, 1976 Husqvarna 250CR, 1981 DT175G, 1988 DT50, 1990 "Super" DT50, 1991 RT180, 2017 XT250
