Review on Motorcycle Breather Off Road Motorcycle Black All by Jerry Moody

Out of 10 pieces, all 10 react very differently in the test, but the most disappointing thing is that supposedly one-sided air duct but with those that work better (maybe 2 out of 10, what comes). a free passage in one direction and a side passage in the other direction, not very close. Maybe it works for others, but for my needs it doesn't work as expected
