What do you guys think is the cause of having oil pressure when cold but once it gets hotter and by hotter I mean the bike running and getting to operating temperature the oil pressure stays at about 8 p.s.i. and wont move even if raising the rpm. New bearings where put in motor but old oil pump was used. Any input will be appreciated.

You might need a new oil pump. Cold oil by definition will have higher viscosity which causes higher pressure. You might have some tolerance issues in the pump or the check valve spring might be weak when it heats up.


Other than that, there could also be tolerance issues with the bearings.
