If you bought the lower cowling, read this
When I purchased my lower cowl, I installed it at the dealership in the parking lot. No problem after you figure out where all the parts go. However, I noticed the cowl touches the radiator hose on the right hand side at the top. This can't be good for the radiator hose long term. I pulled the top bolt and took aviation snips and trimmed a little quarter moon shape off the cowl. After an all day ride, I noticed that the radiator hose had shifted down and out a bit more, so I had to trim a little more to keep it from touching.
I think I could have achieved the same thing by loosening the radiator hose clamp where it goes into the engine and rotating the hose a bit to move it away from the cowl, however, a little trim seemed to work also.
Check your clearance on the hose. I think over time the cowl, left to rub would make a hole in the hose.
