F3 Engine Rebuild
I'll start off saying nothing was wrong with the motor. Everything tested out to factory specs. Need to get more out of the motor which means rebuild. I didn't take step by step pics because the service manual has that.
I started by taking the engine apart still in the frame. Makes is easy to pickup by yourself to put on the bench.
The inside was really clean not what I was expecting.
The cylinder head was completely taken apart and the exhaust side was ported.
Stock crank vs race crank.

I sent the upper case out to get over bored. I forgot to take a picture before I had the cases back together. New bigger pistons installed.
Next step was to make lighter and just as strong if not stronger motor mounts and spacers. All the weights are in grams.
Just one of the stock engine brackets.
Both of the brackets I made weight less than one of the stock ones.
The engine uses 5 spacers to set it in the frame. The smallest one wasn't worth making so its not in the picture.
All these spacers weight less than the big stock spacer.
Put the engine back in the frame. I have the new over bore head gasket, just to cold to work on it.
