Do a poll. Has anyone on this forum PERSONALLY experienced a inner cam bearing failure? The answer is NO. Many will tell you about a friend that had a failure, but non have experienced them selfs. That is a myth that has grown feet and has not stopped running. I read another post that a guy has 80,000 on his 09 Harley and has only completed normal services using non syn oil and has experienced NO mechanical issues. Bike is all stock, no upgrades, just rides the bike and changes his oil. I changed my cam myself and did not change the inner bearing. at this time i have not experienced any problems.

No need to replace. The bearings in the older models did have a recall may years ago. There is no need to change the bearing. The OEM bearing are of good quality and will last as long as any other bearing in your engine. If your being told that they are week, then why not replace the crank and rod bearing also? Just my opinion. Good insurance would to be buy the extended warranty.
And yes, you should change the sprocket side crank bearing. HD replaced the twin tapered Timkens with a big INA to cheapen and speed production, and mechanics immediately began seeing engine destruction caused by the too-weak bearing. Just because it hasn't happened to you or anyone you know, doesn't mean it isn't happening.

"I read another post about a guy that has....."
Irony anyone?

Yes you should replace the bearings. Check these out and you will see the difference.
Your dealership parts counter will have the right size cam spacer. If you can read the writing on the stock spacer then get one that is .20 thicker. If you can't read the writing then bring the spacer. My stock spacer was .110 not .100, so you see where I am going here.

I plan on installing SE 255 cams into my 09 street glide with 4k miles. Do I really need to replace the inner cam bearings during the install? The tool cost for a one time use is a little high. Has anyone not replaced them?The miles are low and they are already roller bearings, is it really necessary? If so, does anyone want to rent me thier tools?
How do you feel about that?

My dealer stocks the Torrington bearings and installs them on every cam change they do.

I've never heard of an INA inner-bearing failure either, and for every cam job my dealer does they replace them with the INA's in the cam-install kit. For me, if you're going to change them, buy the Fuel Moto cam-install kit and do it with the full-complement type (Torrington-Timkin) included. Or, buy the re-branded SE bearings.
