I have 7,023 miles on my twin cooled limited with zero issues so far. I have read many threads with the twin cooled bikes leaking coolent early on but the number of threads have seamed to slowed down lately.
Might have to do with the bad weather we've been having, not a lot of folks out riding yet, wait until spring. I had my housing replaced but haven't ridden yet so I don't know if I'm fixed or not. Glad to hear with your mileage you've had no problems, encouraging for the rest of us.
Mine never leaked, it did burb once. I have had the filler neck replaced. We haven't experienced a bad weather here and I have been riding almost every week, even in temps where the fans kicked in. No issues yet but I'm taking a wait and see attitude. I don't spend any time worrying about it tho.
Have about 3500 miles on mine with zero issues. They did the Product Program change on the filler neck when I had it in for the clutch recall but I've not experienced any problems with the bike since I go it......knock on wood....
I've had my fans come on right after I shut down the bike, I assume them not coming on was part of the issue. It's a closed system with an expansion tank, the system was still hot, the fans didn't come on and the expansion tank ran out of room, hence the pissing of fluid on the ground.
