just a short review on both forks. I have some closed chamber forks that have been revalved by brokenlegs. they work brilliantly. deflection reduced by approx 30 to 40%. exellent over rocks , tree roots, rock splats, yet still take massive jumps & drop offs without bottoming. this man really knows what he is doing. I have just had him do a set of open chamber fors off my brothers 300 exc. he has spent some time working out the valving to react very similar to my closed chamber forks. i put them in today and took it for a rip round a bit land near my house, then took my bike round with the cc forks in. this initial test showed that both forks felt identical. mark did say they prob wont take real big hits like the cc forks. I have yet to test them on some more challenging terrain, and will post a more detailed review after . initial test shows brokenlegs has totally transformed these open cartridge forks . would reccommend anyone wanting a suspension revalve to give him a try.

closed chamber forks. v open chamber. revalved & tested.
Not a penny lol I don't need to 
I've pretty much got this suspension lark licked now, black art my arse!!!
The worst part was the initial cost of the special tools required which is still ongoing
Constant testing of different setups to find out what works and what doesn't. The open chamber forks I did above were the older 03 first gen 48mm where renown for being very poor from the off, just proves with some internal upgrades you can still make these older forks work
Every time I ride my bike it's valved differently.

Hi mark both sets with bleed shim in (12)ive noticed for faster riders remove bleed so it does not blow stroke too much I've just done a set of cc off an xcf for a friend with new stacks new springs skf seals bike is now transformed.......hard work pays off buddy well done mark I am near as damn it now with my open chambers too .....you thinking of going 4 popper again buddy
Jerv as you know there stock stacks above have you changed that shim now as per the stack I sent you
It's been hard work but I'm getting real close on both open and closed chamber forks for different years, the spread sheet is growing.
The open chambers have there limit of user-ability but are still good forks once setup. The stock 12 forks 2st are good, the 4 bangers still need a bit of work and close up the mv float.
You need to flow the mv now and stick some good oil in preferably not p@@@@@ne
Next step is the rear end now the shock vac pump is all setup

Nice work. Is that a bleed shim on the KTM RB Stack? Got my OC EXC250 2011 forks sorted and some bastard nicked the bike. Running a 2012 250 xc now with std CC forks-love the way they can take a big hit but would like to take the edge off them on the small stuff/ rocks/pot holes ect. Do you think taking a couple of 24's out of the base (as the Berg set up) would help?
Cheers.
Cheers.
Set the bv as the berg and change the 12mm mv bleed for a 16 and remove the 15 bleed from the rebound this alone will make a world of difference
1.2 bar bladder and 340 mm of oil as a start
The main problem with the linkage bikes is the rear shock setup is poor, it blows through the stroke to fast and makes it ride like a chopper which makes the front end seem harsh. You need to add some face shims in the shock ideally to hold it up in its stroke but softening the front will help with the balance.

mr stevens has done mine mark, you still might know and yes I'd say there pretty good forks very responsive
I agree with closing mv float to which I have done and went practising Sunday and was mega,cc forks are always going to be stiffer so altering base valve a little but concentrate on opening up float a little so oil flows a little it is all down to ability.
Mark has got where he is today due him testing testing testing and now is getting rewarded with some good set ups a lot of work and tinkering is paying off fella

Ive got to learn how to service these forks, and what i'll need when i get back on the bike, hopefully in 4 weeks time fingers crossed
I'm actually not bad stu, i cant lift my arm, but can feel ive had extensive work inside my arm, and its still throbs after a little movement like when a broken bones healing, but im going out of my mind i just want to ride, ive bought tyres,tubliss a alloy sumpguard a gnarley a topend kit lol Ive just got to get out and stay injury free m8 lol
I've just bought a 2011 KTM SX250, and the previous owner said they had spent over £700 getting GForce to revalve and set the suspension up - I tried the bike for the first time at the weekend, and it's a great bike, but I found the suspension quite harsh on the small bumps - landing on the bigs jumps was fine (they said it was set up for 12 stone and I'm 12.5 plus kit) but going quick over small bumps seemed to shake me to bits!
So, what do you guys recommend? I'm guessing Brokenlegs supplies the shim kits as per this thread?? What about the rear shock? or do people send the forks and shock away? Sorry for sounding like I don't have a clue! new here and new to KTM's!
