    Yeah, I haven't seen any real evidence that it's an issue on a Sportster. Maybe it isn't. Just from my experience with my XR and similar stories of others, as well as my understanding of cush drives, I'm a little less comfortable with it. Maybe I'm just overly cautious, IDK....

    Slow, if I could just focus a couple of days to it, I'd be riding. Well I think that's all. I need to take about 10 thousandths off a spacer to center the front brake, wire the tail lights, blinkers and work out the chain tensioner.

    And you're using a KTM 525 fork/clamp setup?

    I don't think I'm going for that amount of travel. I just want to be able to run down fire roads and similarly maintained dirt roads, not go full off-roader with it.

    I'm using yz450 forks, with modified internals for the sportster weight.

    You do not need this level of suspension for normal fire roads. I believe a set of sport forks with internals revavled for scrambler work would be great. It would be a better scrambler than you can get from a factory.

    That sounds good to me. From my research the Sportster suspension just plain sucks all around. I know it'll need to be addressed for what I want. I also wouldn't have a problem with switching out the forks and/or triples as long as I can find something that'll work, be readily available, and not overly expensive.

    To make it work right you need to keep balance. So long travel forks mean a lot of work on the rear suspension. Not to just level the bike out, but to keep the travel balance, and keep the anti squat values in check with swingarm angle. If you have full length sportster fork the call Motocd.com and get him to sell you his new dualsport valves. He won't want to, but tell him I sent you and the Klr valves should work. If he needs a fork to test I'll send him I spare I have. I tried the new valves he designed and am very impressed. That would save you some coin and trouble. Just change the fork oil and drop in the valve. I'd help you in any way I can.

    Much appreciated. I have yet to buy a Sportster for this project so I don't know what forks I'll wind up with.

    I'm trying to find the cheapest 91 or newer 883 I can. I'm not overly worried if it runs or not either as I'm planning a 1250 swap, I just need the bottom end to be good.

    Since changing my wheels to 21" front and 17" rear with tkc80 tires I much more conferdent in the project. But an up coming rally may call for a river crossing. With a water depth of 12-18" (no deeper I hope ). The ride will be 9000km round trip. I have a choice between an 8 year old Kim 640 adv. or 2013 sportster (with wheels and tires ) .But if I take the sportster what areas need water proofing. Has any one ridden throw deep water with a sportster.

    One of the scrambler builds has a rear nissin master. I think either it's a pull action or he fabbed up a bracket like this:

    http://www.fabkevin.com/shop/brakes/remote-master-cylinder/

    I don't know what it'd take to hook it up to stock caliper if you want to take that route--thread pitch is 1mm if that helps. Fab Kevin also makes linkages, but they're way over priced also. I don't think it'd be that big a deal to find the dies to make them. bungking sells the heim joints and brake stays as well.

    Some guys have been relocating their masters up under the frame--I don't bother asking about it, I've derailed a guy's shop thread by posting my build. Either it sucked that bad or was so good he got pissed and stopped posting :lol3
    But they're probably using a cable bracket like the one I posted above. Oh and BTW I tried looking up what year sportster mag had the cush drive, ebay had one up for sale but it seems like XLforum and hog aren't that concerned, but I know they carry no weight here. :D

    That's a good looking ride, is that a Buell front on it?

    FWIW I installed Progressive springs in my 2002 sportster; used 7/8" spacer for preload. So far they have handled all the dirt, gravel and mud i have thrown at them. Simple installation and less than $100. Installing a set of valves as mentioned from various companies is another route. John and Randy have far more experience with these than I do( I have none as a matter of fact). I may eventually drop some Ricor Intiminators in to see how they pair with the progressive springs. This is a less costly alternative for rigid mount sporty's with out having to replace forks and triple tree's.

    Progressive springs

    Another option if you end up getting a "rubber mount" Sportster is the Progressive Cartridge mono tubes. First class suspension and you can use the stock forks. Would be more than enough for your application. Cost would be less than $250 if you shop around. This is a product that I wish I could have installed on my 2002. It will give you all the features of a 1200S front suspension; but with a lifetime warranty:D

    Ohlins suspension kit including rear shocks. Front brakes are the full floater kit. Bike was set up for previous owner at Bartels in Marina Del Rey although the XRCR bodywork was done directly through Jewel in France.

    I understand that Ricor generally recommends linear springs for use with Intiminators. That said, some do use progressive fork springs with 'em.

    When I spoke with a technician at Ricor they did recommend that I start with the stock springs. However, he did say they would probably work well with the Progressive springs. When speaking to progressive; they did not admit to any testing with the Ricor; but they did speak of another valve(the name escapes me at the moment) that they had worked with and it had performed well. I opted to start with the progressive rate springs and if I felt I needed something that would improve the suspension in rougher terrain I'd try the Ricor's. I keep things pretty slow on the back roads, so for now, the Progressives with the current preload setting are more than adequate.

    Race-Tech Gold valves Rod, they make them for lots of applications.
