I'm somewhere between 6'2" and 6'3" and have weighed as much as 245lbs riding my current setup. Just a few things to keep in mind, all bikes have dive, it's how fast and how far they dive. I know that is stating the obvious but you can't dial it all out and you wouldn't want to if you could. There are lots of things you can do to adjust it. Change oil weight. Change oil level. Stiffer springs. Emulators will NOT eliminate dive, they just slow the rate the springs compress. To say that another way, you get the same amount of fork travel but it doesn't feel as bad because you don't get that quick falling feeling. It's the springs that really what determine most of the real suspension items. The damper rod or emulator just control how the impact or rebound affects the springs. What Yimm said is factual but you would have to do that with a straight rate spring which the stock spring is not. I would also go back to the HyperPro spring. It will NOT bottom or bind like a straight rate spring can. When you cut turns off that spring you are shortening it's max travel at the same time. To repeat myself, you have lots of options. Add more oil. Stock is 145 mm and RT recommends 125mm, that almost an inch less spongy air to compress. That could cut down on dive. Put 15wt oil, it will slow things down, but maybe give hydro lock in damper rod as well. Lots of pro's and con's. Bottom line is, pick something and try it. I'd say springs first, then oil and level variations, then emulators, more oil and level variations, then shop for a new bike if the stuff doesn't work. :-D
