Predator 6.5 dies when running on bumpy grass/ dirt


New member

I have a brand new out the box Predator 6.5, mounted to a 1 wheel drive small kart. 10T clutch. Completely stock.

Runs flawlessly on the flat pavement/ road.


It will run for a short time on the grass/ dirt with bumps then it will die. I noticed if I run it with the choke about a quarter on, it will last longer but still eventually dies.

Any suggestions are greatly appreciated. Thanks alot
These motors come with an oil sensor inside the block when it bounces around it sets off the oil sensor installed in the motor this must be removed from inside the block
