big end bearings no holE????

Hey, im building a 82 gs750 TSCC engine, just wondering if anyone out there knows why suzuki have not put an oil hole in the big end bearings they are supplying for that engine now. Any help would be appreciated. Thank you.

the oil hole is in the main bearings, there is no hole in the rod bearing (big end) as that is as far as it goes from the crank.

the small end (piston pin) and cylinder walls are lubricated by the oil slung up from the crank.

my connecting rods have an oil hole in the big end and my old bearings have an oil hole to match this hole in each big end. the new bearings have no hole.

I'm with Dave on this one - big end of the rod bearing should have a hole to let the oil in. Am I missing something here???

then drill a hole, put the bearing in the rod to get the alignment with where the hole needs to be and drill the hole.
remember to chamfer the oil to ensure proper flow.

yeah ive considered this option. I dont want to screw around with factory bearings if you know what i mean. Suzuki Australia are telling me that i should fit the supplied bearings and not to worry about it. Id like to hear the same thing from someone who has built one of these engines recently.
