Pull-ups and dips are great to help build the strength but they are basic components and when done without momentum (which a kipping muscle-up uses) they aren't going to help the transition much.
Just from my personal experience. I find muscle-ups to be kinda boring now that I can do them, and since I'm too heavy to string together 30 at a time like Steven, and rings don't just pop out in front of me on a daily basis challenging me to do them, I kind of see them as a fad part of CrossFit, and just one of the multiple workouts that show up from time to time.
What you really need is someone who can do a muscle-up to watch you attempt yours, and perhaps see how your pull-ups are coming along. Heck post a video on here so we can see what is going on in the digital coaching section.
You don't practice parkour, eh?
Muscle ups are a key element to parkour training -- mastery of the muscle up...particularly on bars...is highly desirable by most traceurs.
In fact, most traceurs will work up to just getting a muscle up...then others who are a bit more dedicated focus on reducing the speed to have maximal control through the full ROM. Purely being able to just get over the bar/rings is the first step...explosive pulling taking precedence at this stage. When that is mastered most will attempt to slow the movement down to be under a maximal amount of control through the movement.
Sure...doing a fast muscle up is only somewhat scary at ground level...but when you are hanging from something 10 or 15 feet up control takes precedence particularly because fear doesn't want you to be explosive and out of control.
Not nitpicking - just pointing out that it is easy to get bored of a movement when you don't really have a reason to get better at it aside from "just doing it".
That aside, I wouldn't say anyone is "too heavy" for anything. Being 180# I have been told I am too heavy for a lot of things yet I am dangerously close to a solid straddle planche. It just takes us heavier guys significantly more time to get to that level.
Just check out Bert Assirati, Everett Marshall, Milos Snajdr or any of the other heavyweight names on that list. Determination can take you a long ass way.
