I finally got to take the bike out with the new windshield. The wind has finally eased up and the temps shot up into the 70's. I find the shield does help. I am 6'03 and 260 lbs. It definetly cuts the wind off my chest and moves the air flow up to my full face helmet which is fine by me. If I get hot in the helmet I just open the vents and it's like having a fan turned on in my helmet. I think in the summer it will work well for cooling if you ride with a full face helmit. If your looking for less wind and you're a tall rider you will want a bigger shield. Conclusion: For me and what I want it was a good buy for me and was a breeze (no pun intended) to install. If your looking for less wind, Find a bigger shield that works for your type of riding. And as for the carb covers I think they added a couple of horsepower. It must be the radiation as they did come from a japanese manufacturer :rofl_200:
