Thumbs down Broken rod on stroker crank

Well it was fun why it lasted, riding in the mountains today sound like the timing chain broke, get it home pull the covers itís in time, pull the plug and the piston is not moving with the other crank, I will tear it down one night this week and inspect the damage

Weld it, it will be fine

Well that sucks, what RPM were you limiting too with that longer throw? And also what has the manufacturer said about the failure?

Hopefully it broke at the big end so it wouldn't do a lot more damage.

I was wrong it was not the rod, it yanked the wrist pin out of the piston

Too much force at the top of exhaust stroke.
