Hope not in the wrong forum, well anyway it would not crank and i looked at everything then i poured a little liquid in the exhaust hole and the left valve leaked it backed out, the head is off now also, but all the others hold liquid and the left exhaust leaks it out.  Will this cause the predator to not crank

by not crank do you mean it will turn over but not start? if so i would say yes either your valve is bent or is not longer sealing either way it is likely why it will not start.

yes will not start, my cousin was riding it one day and it shut down on him and would not start back, so i figured the valves needed adjusting but that was not it.  Looked at everything else and then sprayed some carb cleaner in the intake and exhaust ports with the head still on the motor and it leaked out on the left exhaust side.  So no i have it off and it leak from around the valve, i didn't think it would keep it from starting though

yeah if it leaks down and will not seal you are not going to get compression and burn. i would be willing to bet that is your issue.

got engine put back together with new intake valves.  not cranking still, intakes were cupped like hell, will bad rings also make engine just stop running while riding it.  This really getting annoying, thanks

double and triple check your timing. make sure the flywheel woodruff keyway on the crank is not sheared.

pulled engine apart again and removed piston cylinder and um surprised the rings did not break from binding on the gunk stuck inside the cylinder.  so screwed up, needs to be replaced.  Leo you quick dude, i appreciate it man
