Topic: dynoman cb550/650 pistons

[boogiedude]

has anyone done a build using the dynoman DP572/mdr or DP592/mdr pistons? They're desgined for running a 650 head on a 550 block and bottom end. Looking for opinions/experience on the topic. I'm in the process of laying out my build plans and didn't know these pistons exist!

That I know of nobody has used these, yet
I've got a spare 550 motor and a 650 head and will be trying this in the future but it won't be anytime soon. Make sure you use the early 650 head if you want to keep the 550 cam cover.
