ok fork question. one of my forks is leaking should I go ahead a rebuild both? if I have to do both I might as well up grad it to. I was just wondering the best place/person to get parts from and what all should I get? List #1 just enough part to fix one fork from leaking.

List #2 parts for up grading the set and leak repair.

I'm going add this here for those of us who lowered our forks for looks but would like to get that lost travel back and possibly do some of the mods listed here. I'm one of those guys and since I have standard bars, I'd like to keep my top clamp. So I decided to look into have my fork legs shortened and rethreaded to accept the stock top caps.

I found an experienced guy on youtube and contacted him. $75 a leg. He's experienced and is into cool stuff. I'll be sending my fork tubes to him this winter.

Gary: I am not sure shorter is an option.........they have this statement on their webpage:

TNK Tubes are direct OEM replacements in standard length only, there are no shorter or longer options offered for USD forks such as Sport Bikes. Some longer than stock tubes are offered for crusier models and some vintage HD. Please use catalog download to view these options.

I just installed Progressive Suspension part number 11-1153 fork springs in my wife's 2012 and it really helped (Thank you Gary). The stock fork springs are too light and have way too much preload.

Now the bike is much more compliant over small stuff yet resists brake dive and bottoming. It used to be like a pogo stock and was constantly using up way too much travel up front. Just coming to an easy stop caused the forks to use up a bunch of travel.

I used the bare minimum for spring preload (2-3/16" spacer) and Race Sag is 25% with my 150 pounds on it. Still could use a lot more rebound damping.

We often ride two-up and the bike has saddle bags so the stock forks were really awful. This was a fast and easy way to make the forks much better.

HIGHLY recommended...

I should also add here Hagon makes a set of fork springs specifically for this bike as part number 400-049-01.

Our suspension tuner (Bruce Triplett in NC) is a Hagon dealer and this did not occur to me until AFTER I bought the PS springs... Doh!

Bruce is a vintage DR fork genius and one day I will have him do this bike too: http://www.brucessuspension.net

And one more thing... If you do not ride two-up and/or if you are very light you may find the forks to be a little stiff. If so I suggest you use one stock fork spring and one PS fork spring.

Also... I should mention is that the fork oil height is still at stock level (75mm) versus Gary's recommended level of 120mm. The higher the oil level the greater rate of the air spring. I think I will lower it to 120mm for a test...

I did get my forks cut down and it's working out great. It's a nice option for anyone wanting to lower the front end of the bike 2" while keeping the stock top clamp. Rides much better than it did with the 2" spacer to reduce travel.

I'm running a set of stiffer progressive springs with very little preload and a low oil level (eyeball method, for now, will measure soon.) I will also measure the clearance between the fork tubes and lower clamp when I set my final oil level so we know what the max cut off point.

I may add some Race Tech or YSS emulators at some point and Hagon shocks will replace the stock shocks when the blow.
