Installed the DK Custom Oil Filter Relocation on the Wide Glide...

This oil filter relocation is going to make for a clean oil change; I believe dropping contaminated engine oil on the front isolator is one of the reasons the isolator fails and the Dyna begins to exhibit added vibration issues.
I'm sure it's adding additional cooling with the filter out in the wind and it looks great

Got the DK Custom oil filter relocation installed on the Wide Glide last Friday, took a bit of time to get it tweaked to my liking due to my +3" billet shift rod and having a Jagg thermostatic oil cooler adapter taking up additional space but it did turn out very nicely
The kit is very nicely made, the only issue I noted was the cast engine adapter had some nicks on the mating surface and the black finish used on the adapter had migrated to the mating surface leaving it very rough and bubbled but a few minutes with a fine file and some 1500 and 2000 wet/dry left a smooth polished flat surface to mate cleanly against the Jagg thermostatic adapter. It may have just been my specific engine adapter but run your finger on that mating surface to be certain it's smooth.
With the limited space I had I needed the 'In' and 'Out' fittings on the engine adapter in a specific position to clear the shift rod and have the hoses not contact each other. I fooled around trying to catch the threading on the Jagg adapter in different positions so the DK Custom engine adapter would snug up to the Jagg with the fittings where I needed them but the 'Out' fitting ALWAYS ended up at a 6 o'clock position; about the worst place it could be. I eventually used a long 7/8" wrench and reached in from between the downtubes and gently tightened the adapter further using the center 'In' brass fitting hoping the entire time I wasn't over-tightening and trashing the o-ring for the adapter. I did get the 'Out' fitting to an 8 o'clock position which would get me just enough clearance.
The billet oil filter mount was positioned directly under my upper clutch cable stand-off clamp; those clutch cable clamps made life much easier The downtube is 1 1/2" so no shims were required for the oil filter mount. I used Gates 400 PSI reinforced oil cooler hose and #16 fuel injection clamps to connect the engine adapter to the oil filter mount. Note, there is an 'In' and 'Out' on both the engine adapter and the billet oil filter mount!
Getting there, just before tweaking the engine adapter to reposition the 'Out' fitting...
Permanent oil filter mounted, hoses and clamps secure... Done!
Held my breath and started the bike, hoping the engine adapter had not been over-tightened; all good, no leaks anywhere. Oil pressure on the gauge showed no changes; a quick ride around the block and back to again check for leaks. All was well; took the bike out for a nice romp...
Afterthoughts: Most of the problems were of my own creation; running a +3" billet shift rod limited how I could route the hoses and the added thickness from the Jagg thermostatic oil cooler adapter placed the DK Custom adapter fittings more outboard limiting options further but the problems were not deal breakers.
This DK Custom oil filter relocation looks fantastic and should provide additional cooling while keeping contaminated engine oil off the front isolator during filter cleanings.
A very worthwhile mod and I highly recommend it. This is a Watson Approved™ upgrade!

That looks fantastic on your WG. If you're anywhere near as happy as I am with the no-more-mess oil changes, you're gonna be a happy camper.
I have this same unit on my Sporty and Softail, & the other style on my TG. Doing 10-12 oil changes a year (between the 3), it really makes a difference for me.
We're still gathering data on different bikes, but so far we are seeing around a 10* drop on Sportys and close to 15* on Twin Cams. These definitely cool more than the other style we have for the Trikes and the Twin-Cooled models.
Thanks for the great report and photos!
