CB750 / Re: Surprise 812 Yoshi Pistons - but will they work for me
« on: March 20, 2023, 06:55:17 PM »
I did have to get new barrels in the end. I have put this on the other SOHC forum, so I thought I should give an update here.
It has been a long time (ish) since I have added to this thread but I am now able to carry on with this engine. I hate threads that run out without any conclusion.
Eventually after honing and cleaning the bores they were too big, so I found another set of barrels and had them bored.
I also found the right rings, apparently NOS Yoshi 823 ones from a big supplier.
So I can now get on and continue looking at the rest of this engine.
I have put a lot more info about this in a YouTube video https://youtu.be/YcIc5S9Z47g on the Spanner Rash channel.
