Motor cogging vibrating please help

I have a mototec 1600w dirtbike. 

48v with a makerx g300 I put on it.

I got everything running. but it coggs out after about 5mph around 5000erpm. Its like a grinding almost.

I can't get it to go away I've tried everything.

I believe I figured it out.

I raised the sensorless erpm under foc / hall sensor / sensorless erpm. It was at 4000 default. Bummed it up to 9000 and it's fine now.
