Stock 78mm TB and no spacer. I was and still am contemplating a spacer, but it's a lot of $$$ to spend. I'd like to make it myself, I have access to a Cnc machine, but am not sure of the proper phenolic material and the guys who make them don't want to share that info.

 

You're exactly right, I'm not sure which type to use.

 

Any updates on this??

 

I know he was debating a TVS upgrade. What info are you looking for?
