TR, That doesn't really help in that we need bearings that are the proper width, edge chamfer and oil hole location. We never thought that Suzuki would use such specialized bearings. This said I've talked to quite a few well know crankshaft firms and this is not a unique problem we're having. That is why we're on the hunt for a firm that may have proper NOS. This being said thanks for the info. I is very close to what our cranshaft build had told us to use sadly they have retired just before the plague with no way of contact.
TR, The main reason I keep trying to find a proper set is I'm sure there are several out there that I only need to locate. This is because up until the late '90's early2000's this size was pretty much the go-to bearing for 600cc and up Suzuki multi's 650's to 1100's so all I need to do is keep looking. Right now we have found about half of what we need to have 'sOnce new old stock is gone on a part like that, you either make, modify or substitute something that will work, or the machine is on the way to becoming non-serviceable. Seems to me you're looking for 35mm shells with a thickness of exactly 1.5mm and that sounds like something that might have been used on a slew of different machines. If you can't buy it by part number then you will need to buy it on spec. Width, chamfer and holes drilled in them is something you might even be able to work around, an oil passage groove down the middle of the bearing (as shown) would near impossible to add, so if you need that and can't find one with a similar feature, ya'll might be out of the obsolete suzuki racing business before long.
Woodsman. Thank you for your try. Neither firm has either. Suzuki has part numbers one for the top bearing and one for the bottom. I was surprised that they don't come is bearing sets as do most everything else I've worked on. You order one bearing at a time so for the GSX R1100 W you ordr six top bearings and six bottom bearings. For me the good news is that I've found lots of bottom bearings and they are the ones with the oil hole so we may be in good shape after all/ Thanks again as you did help us find lot of one side. Cheers to ya !

Yea it is strange they come 1 bearing half to a box 12 boxes for a rebuild. My machinist was saying that for the cost of packaging that way they could sell you a whole engine set in a blister for the same price as 1 journal in bower like Suzuki does not to mention how many times does someone replace one bearing half ?Glad you mentioned it because I found it pretty strange they only sell one at a time. Never having bought any for a bike I thought maybe that was the way the OEMs sold them.
The likely problem is they don't really know what size shells they are making until after they produce it, then quality control has to determine what part they just made and code it, or if they made a piece of out of tolerance range scrap.
I'm working with a fellow who was a second level Suzuki factory engine builder.. What I was told is as the cases are aligned bored the factory guys check the bores with a mice. Often it takes the removal more material to get the bores true that means a different bearing. So the cases go into stacks with each pile representing a different bearing size to maintain proper clearances. Seems to be a wee bit involved when i compare it to the British and American blocks I'm used to; I wonder if it's the best way to do this when working with thin aluminum cases where you can't really use things like torque plates to keep things from moving around.The likely problem is they don't really know what size shells they are making until after they produce it, then quality control has to determine what part they just made and code it, or if they made a piece of out of tolerance range scrap.
