Valve seat contact width
#4
the question is not that.
but what parts were used, china clones?
The cause of the leaking is not known.
1: burned valves.
2: non concentric how.
3: WARPAGE.
4: CHINA JUNK PARTS, THAT HAVE NO FUTURE.
5: WORN OUT, ? AT JUST 50K MILES?
6: same with seats.

if you grind the valves, the bent ones are obvious, or from heat CAUSED warpage

a valve runs cooler the more contact there is on the face.
IIRC, the 2 angle cuts are for flow, a compromise to above.
they make 1 angle valves for 100 years with no problems.

finding quality parts today is not easy, and Suzuki dont help there either. It's no Honda/Toyota.
