The parts sites say your bike AND the Ultra Limited Low have the same primary cover, part #25700418... so you already have the narrow cover used on the "low" bikes... I know in the twin cam line, all the touring bikes got the "low" narrow cover in 2016... they probably continued that for the M8 bikes...

A couple of FWIW tips....

I got into a habit, when working on my bikes, cars, and boat... Anytime I disassemble something, I use a thread chaser on the bolts and mounting holes to ensure they are clean.. that lessens the chance of an "issue" during reassembly. I also use a compressor to blow out any blind holes before reassembly.. It will remove any oil trapped in the blind hole that can cause a hydro lock condition, that can crack a case at the blind hole...

I have an OEM HD primary cover gasket on my 2016 Ultra Classic. I have had the primary cover off 3 times, and reused the same gasket, with no leaks... I bought a new gasket the first time, but decided to reuse the old one until it leaked... The new gasket is still on the shelf..

Have fun working on your bike... I always do..!

 

???? You sound like someone who will be asking the question were did this puddle of oil came grom this spring. So save yourself from asking by adding some of that florescent yellow oil dye when you go back together.

 

Not sure if cheap is were you want to go. Their last catalog release is going on 5 years ago. That should tell you something.

 

It's a good idea to have a outer primary gasket on hand, but like Scratch said, you can reuse the OEM gasket again without any problems if you're careful with it. I've reused my current one probably 5-6 times. It's a quality metal core gasket.

That said, if you're really going to dig into it, have a T-70 and a 200+ pound torque wrench ready for the Compensator and a 100+ pound counter clockwise capable torque wrench for the clutch hub.

 

I was thinking of removing mine a few weeks ago while I was changing fluids then I said why...then I looked at the bolts behind my foot boards looking at the lines and everything in the way... I said screw that , it runs fine.

 

Thanks for sharing this great information.

 

I wouldn't remove the cover just to look. I will make up an excuse. First time I pulled mine, it was to replace the clutch friction plates, because I was curious how badly worn the originals were after 30k miles of heavy use. After I got the plates in and everything put back together, I measured the thickness of the old plates. They had some wear, but were still good to go for many more miles. I replaced "too soon" for sure, but now have some peace of mind knowing my clutch won't likely start slipping out in the middle of nowhere. New set of friction plates cost a little under $200 at the dealer. Don't forget the three coil springs, cost around $10 each.

 

Okay so I finally received the gaskets and tools. Shipping these days takes forever. BTW the Cyco gaskets appear to be high quality ( I have no affiliation with the company) I will replace the gasket.

No surprises inside. Everything looked good, all fasteners were at proper torque. Very little wear on the tensioner pad. There was also nice slack in the chain so it was not being over tightened.

I was thinking about going to a Hayden tensioner while I had it apart. I read a lot of positive reviews on them. Then I read a bunch of negative reviews.
Then I got to thinking I had absolutely no problems or noises with the primary. So now Im thinking the Harley tensioner will go back in. It appears to have a lot of miles left.

Waste of time? Maybe for some but not for me. I enjoyed getting inside and now knowing the bike is good for another 30k.
