"........you betcha, had the fork oil changed as soon as I got the bike. The regular Harley Type "E" oil was used, so nothing of any heavier weight than stock, which admitedly might have helped, I still get a severe amount of fork dive with my bike, much, much more than with either of the Touring bikes I have. Rides OK going down the road, but braking and cornering behavior leaves a bit to be desired, at least for my tastes. I'm thinkin', no weight or brand of fork oil is going to make a 30+ year old design perform like a state-of-the-ark...."103tHunDer~~~
With all respect, I really feel there is a "significant" difference in "performance" between regular harley type E fork oil and Bel~Ray 20w Fork Oil.....but perhaps it's only in my mind and has no "performance" qualities which would indeed make up for a 30+ year design as you are stating.......BUTTTTTTTTTT
Let's do a little R&D here....nows our chance [ok it's really your chance, but we are TEAM FXR R&D BOYS HERE RIGHT?].....lol.....besides the "scare" everytime you take a fork tube cap off and that spring wants to shoot out [lol], this is an easy R&D project, if your willing to give this a quick go, it's only what, a 2 hour job at the very most from start to clean up, inclusive of getting to the shop for some new drain plug screws....ok....so drum roll please.....perhaps you "might" acquire a "liter" of Bel~Ray 20w Fork Oil and put it into your forks, putting in an amount of 10 oz for each fork....Then let's see how your bike performs for awhile.....give it a couple of weeks before forming an opinion or say 300-400 miles of riding.....These forks are so easy to change the fork oil with.....Were talking less than $20.00 for this R&D effort here.... How about it?

?
So in general......I am actually getting no fork dive with my FXR2, and I ride it fairly extreme inclusive of cornering in the mountains as well. [BUT come on here I have to [chuckle], and reference that any "cornering" or "performance" here is always quite "subjective" lol, my son-in-law would get a real kick out of this discussion, he is an "experienced" and "accomplished" rider that puts several bikes into corners...ie: Yamaha R1, Honda RC-51, Honda Interceptor as that's the "style" of riding he enjoys doing....ie: the sport bike experience...pssst he's not a "youngster" either....above 35+ for age just so we know we aren't talking about a youngin here...lol] so given the "appropriate" context of our bike's ability to "perform" I will continue....I realize we are all after the best "performance" our "cruising" bikes are capable of....and I am in TOTAL AGREEMENT....ok back to our regularly scheduled discussion....lol. As I tried to articulate eariler I have INDEED had two other bikes perform poorly with diving while applying the front brakes, and I certainly feel "my" FXR2 holds in the corners perfectly well as it is currently being run......[I am not saying this to hear, then....well don't do
it to your bike.....I am trying in text to speak about the "characteristics" of how the bike "seems" to be performing] I mean I can't go any "tighter" into corners than I am currently limited to, as I have scraped the pegs from the left side and of course the muffler on the right side.....and the bike handles quite firm and tight within the corners....but as we all know dragging pipes or pegs is unsettling.....so given that the ground clearance is only 4.56 inches for an FXR2 and the right lean angle sports a whopping 31 degrees to the left and 29 degrees to the right.....who is to say I have enough ground clearance or lean angle available to me to EVEN say that the bike "could" be handling poorly.
THUS, I can fully recognize Hoist's developing need to adjust an FXR in height in terms of different shocks and front fork alterations creating a improved front end handling experience as well.
So say one decides to increase the following:
29 degrees to 35 degrees is a 21% increase for a lean angle to the right
31 degrees to 37 degrees is a 20% increase for a lean angle to the left
increasing the FXR2 from 4.56" to 6" of ground clearance would require approximately 1.5" of additional height which would be an increase of 32%. If indeed the OEM shocks are 12" on the FXR2 it would seem difficult to acquire the additional height via a shock less than 14" since we all know there is a slight geometrical angle to the shock which prevents a 1:1 correlation. So the shock height of say 13" would create some obvious higher ground clearance but I am not sure of the exact amount....perhaps say another .75 of an inch. which would allow for maybeeeee a total ground clearance of 5.25" which would be a 15% increase. There is always the chance too of increasing one's tire diameter to get a higher "profile" tire which would of course provide even more clearance....so perhaps that's how HD gets the additional clearance as well.
