Building a cb750 after collecting parts for the past couple years. I came across a Yoshi cam chain (still in the box) and a tensioner from a trustworthy source, being a sucker for vintage Yosh stuff I want to put it in my engine. The question I have that I can't seem to answer from the old Yoshi catalogue is whether they sold more than one type of chain..let me explain.
The chain I pulled from the box is a 'peanut' link shape and has 219T stamped on the links along with D.I.D and Japan, the chain appears to be new but is very similar to the stock chain I pulled out of the motor when I took it apart. Looking at the racing parts catalogue I can only find a part for what they refer to as 'gold' racing cam chain with links more similar to the 219FTH style in the picture.
The Yoshi chain box doesn't have a part number that matches the catalogue but could be sold later.
If the chain is from Yoshimura and is the OEM type has it been treated in anyway (heat or cryo treated)?
Any help is appreciated while I go deeper into this rabbit hole.
