Hi there, I am looking for diagrams for a Mikuni 38mm carb and a workshop manual for my Yamaha IT250 - can you help, would really appreciate it - Thanks {Kevin, US via Facebook - Yamaha IT250}
The
Yamaha IT250 was in production for a few years, 1977 up to 1983. The carburetor changed a bit during those years. The
diagram below is from the microfiche cards of the 1983 IT250.

Online retailers that sell OEM parts usually have good, legible carb fiche cards. Try the
OEM Parts Wizard
at Bike Bandit for the earlier years.
For more Mikuni carb diagrams you can also visit
Motorcycle Carbs.com. They have exploded views of many different carburetors.
We do not have a
manual for your bike but Torrent Downloads has a few listed. The Sponsored Results section takes you to idownloadunlimited.com which requires a 3 year membership for around $37.
Torrent Search Yamaha IT250 Manual.
