Frequent lurker here. Before I start, thanks for all the good knowledge here. I've learned a lot with searches. Sometimes the hours of reading don't quite pay off, though.
As such, my long-winded post:
My '07 919 w/ ~11k miles looks great, sounds mean as hell, and has lovely drivable torque. That said, it leaves quite a bit to be desired in the handling department. I don't suppose it's fair to compare it to my buddy's Speed Triple R with Ohlins, but still. . .
The Speed feels "tippy"; like it's ready to lean any which way, and changes direction in a breath. My Honda, though, feels slow and heavy and all vague. The action to make a quick direction change feels more akin to shifting a heavy toddler from one hip to another.
Honesty, even the BMW GS 800 & 1200 I've ridden feel snappier than my bike.
Like most of the guys here, I'm willing to put some dollars into making my bike a quick little devil, but want those bucks to be spent efficiently and wisely. . . and at a pace I (and wifey) can handle.
I'm 6'6 and 220lbs. I've got Renthal lows, but the rest of the position is normal. I do mostly spirited street driving with lots of curvy back roads. Never ride two-up, and don't have any luggage other than my backpack.
Currently, I've got the shock preload at max, and the rebound at. . . I don't remember. It's not the best, but I don't notice that it bugs me too much.
The fork preload is set to full-in, with the last (top) line just below the surface of the cap. The rebound is turned out to about 1 & 3/4 turn counter-clockwise of full-in.
I've also raised the forks by 10mm.
I'm running Pirelli Angel GT tires with about 2500 miles on them. Depending on the day and whatnot, I generally run about 36psi in the front, and 39 in the rear.
All of this has dramatically improved handling. As it is, though, I feel the forks are still squishy, and are doing me no favors in the handling department. Indeed; turn-in sucks, and it feels as though about 1-2 seconds into any tightish turn, the steering gets suddenly quicker and the bike steers me more into the turn. I try to keep the throttle on pretty much immediately after turn-in to mitigate this, but it only helps so much. I've been mucking with rebound settings, wondering if the fork "stacking" has anything to do with this.
Anyway, I've got a set of RaceTech 1.0kg springs on the way. I'm considering installing some Gold Valves as well, but am a little bit at a loss as to what to order or what would really be helpful for my setup. For my '07 bike, do I need both the regular GV *and* the rebound GV? I'm hoping the rebound GV is simply the one big-daddy valve that works with my rebound-adjustable fork, but have a feeling that isn't true.
I'm assuming I'm going to notice a huge difference with my new springs and oil (Motorex Racing 10w). On the same note, I assume there's some sort of difference between stock valving and the regular GV. What is this difference compared to just a spring upgrade? And what is the difference between doing just the regular GV and the regular and rebound GV?
1) What is the difference between regular and rebound GV?
2) What, exactly, will each these valve upgrades do for me? How much closer will they get my bike to turning right the hell in, and feel "tippy" and quick like the Speed Triple?
3) How much of a difference will I see from stock-to-RT springs, just RT springs-to-regular GV, and RT springs & regular GV-to-all that plus the rebound GV?
4) At what point do the fork upgrades show great promise, but are fully hampered by the turd suspending the other wheel?
Thanks for your time, attention, and expertise.
