Default New Oil Pump

My 17 SGS has the original oil pump. I am considering to have the new oil pump installed this winter as a precautionary measure.
What do you think.

No need. If you haven't had any issues by now, you're not likely to. If you need to go into the cam chest for a cam change in the future, by all means upgrade.

27K on my stock pump with a Stage IV. All good.

My 2017 sumped and puked at 15,500 miles, so I have no love for the 10 lobe pump. I upgraded my 2018 Road Glide to the 8 Lobe when they came out. , no downside to upgrading.

Rule of thumb…”If it ain’t broke don’t fix it”
The downside to cracking open the cam chest to replace a perfectly good oil pump is you take the risk of not getting it back together properly starting a whole new diagnostic and repair job.
And I’m not convinced all the sumping issues are/were caused by the oil pump design simply because there are thousands of M8s out there with thousand and thousands of trouble-free riding miles.
For what it’s worth,
Bob

introducing change introduces risk...I generally subscribe to 'if it ain't broke don't fix it' over 'if it ain't broke work on it until it is'

I would do it myself just for something to do if I couldn't ride in the winter, but I wouldn't pay to have it done.

I would wait until you do the cam before you replace the oil pump.

Make it worthwhile and do a cam while you're in there. I was always a little nervous about sumping when I had my 2017 so I get that you want to swap it out.

It's not a difficult job to do yourself.
