I could give two shits.
It's been like hell trying to get the front end to work the way it should on my bike. First I took a quick look at the stem and thought it was a 1 inch big twin stem. So Paul at Bare Knuckle Choppers hooked me up with some big twin cups with internal stops. I'm dealing with a Paughco frame and for some reason just figured it was a big twin neck. It's a sporty neck so after hitting it with a "REALLY" big hammer for a while......... just kidding, Paul said "send them back and I will turn them down on the lathe". So I got them back but realized I was actually dealing with a metric front end. I could get a bearing that would fit the stem but couldn't get a race that would fit the cup and bearing or I could get a race that fit the cup but not a bearing that would fit both the bearing and the stem. Apparently Timken does make a bearing that would bridge the gab but it's only made for use in Africa and I it would take a act of god to get two of those bearings to the U.S. I can only imagine what purpose that bearing is serving in Africa. I toyed with the idea of sleeves or shim stock but after running back and forth to the bearing store 10 times I decided I should just do it right and cut out the old stem and replace it with a big twin stem. Sweet a friend had one about a hundred miles away. Drove up.... got it.... drove back...... removed the old one but the new one went in to easily. got out the caliper and it was under. I was about to make a new one and said fuck it. So I gobbed on some weld and put it on the lathe and took it back down. The bearings fits really snug now. This is just a temporary fix....... I just want to ride the sum bitch!
