Honestly they are not much to look at.....the main changes in the engine that have the most effect are some of the least visible.....All the sleeve ports have been cut to some extent or another...but side by side with a stocker your not going to see much in a photo really....maybe a little I guess....the head buttons are cut...but they look stock ( more or less )....likely the most visible work is on the crank,piston, rod....
