Hi Coolts,

In regards to that grinding noise you are talking about, its more than likely the sound of your engine running rough because it has not had enough time to warm up properly.

To warm it up shut the radiators to allow the engine to heat itself up a little. Give it a little throttle as it gets warmer to speed up the process, although pull back if you hear it running rough. You should be right to take off once the radiator is showing 100 degrees, don't forget to open the radiator when you power up to take-off speed.
