My buddy is looking at buying a used 110 with a TB 143 kit installed, but the owner is unsure of which TB head is installed (TB Race or TB V2)... Is there any distinctive ways to determine which head is which?



Thanks!

The old tb heads just say tb on them

The v2 say tb in the tb logo.

My old TB head, and V2 both have the TB in the logo.

ya just pull the valve cover and look at the rocker arms. Ive seen a few threads on v2 heads with no logos even cause they were some the first ones.
