I changed the top end (piston and rings) at about 50 hours and all looked good. Now at 70 to 80 hours I have suffered rod bearing failure and the top end looks like it has been getting hot. Cam lobes look scorned along with the cam buckets.
Is this because the piston was hitting the cylinder or from lack of oil?
No Suzuki mechanic around here has seen this yet and so I am on my own. Going to check tolerances on the Oil pump gears tonight and see if I need new ones?
Has any one replaced their oil pump? If so what parts did you replace?
