Cam help..
#11
If you’re staying with the same cam, it makes sense to me to stay with the same bearing until you change the, both out. Hell, you’re not even planning to change out the cam plate.
For the bearing tool, you can get them off of eBay. I got one, and will know soon enough whether it was worth the price or whether I should have popped for the Jim’s tool. I’m hoping it serves the purpose one time and I’ll be happy.

I was extremely happy with my S&S 475c cam. Now with the SE cam, I'm still debating on going back to the S&S.

I've been running the RS468 in a 107 since we did the cam testing. It was the second best cam for low end torque, the TTS 100 was the best. If you really lug it, below 1500 in 3rd gear or higher, it can start stuttering. The only time I've done that is coming to a stop light and having it turn green when I wasn't paying attention to rpm and the gear I was in. Down shifting solved the problem.

Yes, there is a reason to change that bearing even with the same cam...
The M8 engine uses the same inner cam bearing that the Twin Cam's used, #9215. That is an INA brand, caged bearing.
The earlier version of that bearing (B-148 equivalent), used in the early 88" twin cams had a few issues. The newer version (B-168 equivalent), from 2007+ model years, didn't have the same problems as the older version. During the time of the bearing issues, however, many replaced that caged inner cam bearing, with a better Torrington captive-needle bearing. The better Torrington bearing became a staple for a "while you are in there" change, anytime people went into their cam chests... Torrington was bought out by Koyo, so the new "go to" inner cam bearings are the Koyo B-148 or B-168, based on engine application.
I just put tensioner pads on a 2001 Twin Cam that I recently purchased. I don't put a lot of miles on it, so I just did the Cyco tensioner pad shoes, rather than the entire cam plate, with cams, upgrade.... I also changed out the inner cam bearings at that time... "while I was in there"...
Here is a comparison of the OEM INA brand bearing to the the Koyo (then Torrington) bearing.......
