When I start my bike cold the engine has NO rattles but after it is fully warmed up I hear the cams and/or cam chain making a rattle. If I bring it above an idle it gets abit quieter again. I was wondering if putting in a stronger pressure relief spring would help? 02 wideglide 95", 211 cams and the se oil pump/cam plate upgrade. Bike runs fine but feels as if it is low on oil pressure at an idle, letting the cam chains rattle. I do hear a bit of a whir at speed but have deduced that might be the torrington needle bearings transferring a bit of noise, which doesn't bother me. I also have the -b lifters in it. Suggestions????
