Vented Trans Cover
Install went without a hitch and I like the solid billet aluminum cover as opposed to the MoCo's cheap plastic one. I installed the stage 2 cam and haven't seen any signs of pushing oil out the breather. Don't have that many miles on it yet, I'll repost after I get back from Sturgis in August.

Great product. You’re not gonna find a better price than Biohazard Cycles either.

M8 Checkm8
Product itself is great- for the money, it could come with an actual catch can (option) and a better and longer hose rather than the cheapest generic rubber hose. No complaints about the actual part, just the lower end accessories in the kit.

Exactly as ordered
Only installed it a couple of days ago so can't rate performance but it did install easily and had all the parts it said. It definitely looks and feels like a quality product.

Trask / Transmission Vent
Excellent perfect fit and finish. Unknown to myself the transmission cover on my HD is plastic. Come on guys. The Trask cover works flawlessly. The install takes a little while just because of where it's located. After 500 miles no oil at all in the throttle body & no oil in the air cleaner. FYI I have a stage 1 on my 2021 HD. Nice product worth the money just mho.
