Geimer,
Thanks for the warm welcome

So far I have been lurking around here reading a lot but rarely post.
I'm a noob on Triumph S3, and US motorcycle market in general, but at least, I've done my research on this valve before I start posting useless thread

.
I searched on google and only found Kawasaki Ninja owners have used this valve.
I have a '00 Speed Triple 955i.
The reasons why I want the valve:
1. Convenience.
2. Reduce the chance of stripping the thread doing oil changes.
3. Easy to take small sample of oil analysis.
Thanks for letting me know that the oil pan bolt is magnetic. I will reconsider the use of the valve.
For concern such valve will increase the risk of hitting rock/ground, I will check the clearance again on how much lower the valve is going to be compared to the Purolator Pure One PL14610 (longer than OE) that I am currently using.
So far, I haven't experienced any issue of hitting anything with Purolator filter but I will take that as a consideration.
Thanks again for the replies!
