How do I fix this?

My windscreen just started buzzing really badly at certain RPMs, usually the ones I cruise around town at so it's really annoying. If I lift up on the windscreen it stops, but I'm not sure how to adjust it. I can't find any loose bolts either.

One other thing, since I've had my bike (new) the front brake has always squealed when rolling to a stop, from about 5 mph or so. I've cleaned off the rotors with a rag, but that didn't work. Should I try brake cleaner, or is that stuff going to do damage to something?

Thanks for any help.

Definately use Brake Cleaner. You might have best of results & I use it pretty constantly with no ill effects.

Hit it with a trusty BFH!

there's hope in the words and emotion in the eyes
it's so easy to be misled by the savvy gentle guise
and like fools we trust the delivery
but it's all just drunk sincerity

brake grease on the back of the pads. THE BACK!

as for the screen, either its a loose bolt somewhere, or just take a piece of foam and jam it in there

Yea my windscreen buzzes too.. if I grab the left side and hold it against the fairing it stops. It happens between 6.5k and 7k.. it's annoying but I'm too lazy to do something about it.

Its pretty easy.
Park the bike, and take off the calipers. They should be held in by two large allen bolts. You may want to pull the little clips out of the front fender, so you can free the brake lines. Pull the calipers off the wheel (they should slide right off). When you have them off, do not pull on the brake lever.

now in the back of the caliper should be one long skinny bolt that goes right thru both pads. Remove it, and the pads should come out. Take a screw driver and push the pistons back into the calipers as far as they will go. Apply grease to the BACK of the pad, and put them back in. Reassemble in reverse order. After you are done you will have to pump the brake a few times before they start working.

I'll give it a try if I feel like I'm not going to mess it up.

But why does lubing the back of the pads help w/ the squeal, b/c it seems like it would be where the pad contacts the rotor that causes it to squeal, right?

Sometimes all that is necessary is to shoot the brake free up into the bads & calipers, just to get rid or the dust & crap from the road & dust from the pads. Clean off any excessive fluid.

You might give that a first try & if not the answer then follow the advise of Vash. Often that was all we did at the shop & customer was surprised & pleased for some length of time.
