'99-'01 Speed Triple intake valve

Used valve with approximately 8K miles. Notice the severe wear on the face, caused by having to wipe across the seat in order to find center, which is the result of excessive valve guide clearance. This wear can cause a leakage as well as a reduction in low lift flow.
