Just put the cases together on a derbi variant rebuild. Nothing turns except the crankshaft. I put a pedal on the pedal crank and it won't budge even a cm.
Anyone have a clue of what I should look at? I am about to break it back open a second time.

Is the head off? I can stand on my pedals and the motor won't turn over without the decomp pressed in, but still turn it by the flywheel.
Did you use a gasket or just motoseal when you put it together?
Take it apart. The sprag/peanut/clown collar clip was not installed in its slot when you closed the case.

Yeah that thing is a bitch even with possibly the best exploded diagrams known to moped-dom
I took it apart for a third time and excaberated a exterior crack into a full blown crack all the way through the case. It's a piston port tt and was driven like a dirbike so I got the case in banged up shape to begin with. Internals are flawless, while looking for a new case (used) someone offered me a 74cc Gila piston port that I'm gonna grab.
Dude those cases need a gasket to shim the transmission correctly. Double check your assembly and cut or buy a gasket.. that poor derbi
You don't know the heartbreak I had when I saw the crack... But I couldn't blame myself 100% cause it already existed prior, just on the surface exterior... At a stress point (pedals), my guess is they went off a jump at one point.
Dude jb weld and run that shit into the ground
If that's aluminum , why can't it be welded ?
