Honda S65 oil lines
« on: June 23, 2023, 01:32:21 PM »
After 8 years, finally getting to my S65.
Removing the carb, there are oil lines that from the crankcase to the carb and back to the crankcase with banjo fittings. Any idea what they are for?

I have an S65 that I bought for my daughter, it does not have oil lines going to carb.
However, my Kawasaki H2 750 does, the oil injection system pumps oil to them for lubrication.

The Honda S65 was made from 1965-69. https://www.motorcycleclassics.com/classic-japanese-motorcycles/honda-s65/   Are you working on a two stroke like a Suzuki ?

My bike is not an S90, it is a Asian model not imported to the U.S. by Honda.

Can you post a pic of your bike? Maybe someone installed a two stroke motor in it.

 I have a S65 that i rebuild few years ago. The oil line that goes to the carburetor is to prevent the gaz from icing when the temperature is low. It keep the carb a little bit warm.
