Once I went back to my pits I started it up again and got it running at temp, I then sprayed a small shot of brake cleaner at the flywheel and the engine died straight away. I am lead to believe this is the tell tale sign the front bearing is leaking and allowing air to get into the engine and mess the tune and cause flame outs. Any idea's? was this the correct way to converm the bearing? Is there anything else I should do?
