I got a 4" cowl hood by Goodmark from Summit also, the passenger side
does not have the same curve on it as the fender, runs about 1/4" higher
Also the cutout for the airfilter was´nt off center to match the offset of the motor to the passenger side in the frame.
Having had it shipped to Spain I had to weigh up living with it or the big hassle of getting sent back..................I´m living with it and it pisses me off everytime I see it.
Not what I expected from a big name company.
Call Summit about it.
