I will say this, after 11 years and 100000 miles I still have the same T27 Torx screws on my bike...hand tighten them only and no anti seize ... I have stripped Allen heads Before, I certainly don’t think they are better than Torx.
Good luck with your choices.

 

How did you strip an allen head? Was it just over-torqued when it was put in the last time? The recess area where you put in the allen wrench is a lot deeper than the area for a torx. It seems like a torx, because of that, is a lot easier to strip.

I'll admit, I'm not much of a wrench, but I do some work from time to time. And when I do, it seems that some tech before me at the dealers last service, has tightened those darn torx screws so tight it's hard to remove them without stripping at least one. THAT'S why I am so paranoid. For yu guys that always do your own maintenANCE, you never over tighten those screws so there is never a problem removing them..

 

Even after they worked on my bike, I’ve had 3 Compensator changed under warranty before the bike had 72000 miles and I never had an issue. I do most of my own maintenance. The key is to have the proper tool, I buy good T27 bits, Advance used to sell Thorsen and I bought several when I worked there. The Allen heads I have strippped were tight and I admit maybe not using the best tool. I like the positive contact of Torx, that is just me. I am not bashing Allen heads at all, I am just saying I don’t have any issues with Torx. If you feel more comfortable switching them to Allen , go for it. If you keep using Torx, just make sure that 1-use the right size 2-get it seated properly before starting and 3-Buy good quality tools to work on your vehicles.

 

I figured out long ago that if you run the bike up to normal temp (like ride it 10 miles), park it, and immediately attempt to loosen the T27s, they back out easily 100% of the time without issue.

 

I usually do this as I feel the fluids flow a lot easier out the machine.

 

Notgrownup hit the most important point. Use QUALITY BITS. I would never use a $0.50 Harbor Freight bit on a $25000.00 bike. Because, with a T27 bit, "close enough"... isn't.

 

"get it seated properly" is also a key. I appreciate the info. THX!

 

Good tip!! That may be the answer to my whole problem...well, that and the tip NOTGROWN gave about "seating the bit" properly. THX!!

 

Did you find a washer is needed/required if you change the torx screws out?

 

I use a battery impact drill to take them out with out stripping them.
