Dirt Bike Air to Spring Fork Conversion - How To Install the Race Tech Spring Conversion System

[@marinedad2007]

What size micro bleeder or make will fit the racetech cap?

[@The_Backsmith802]

What’s the length on that spring? Is it 740mm? Do the race tech springs work with the WP single leg conversion kit?

[@jakedragsknee]

Is the medium spring too soft for a 220 lb rider?

[@onlygazza]

Do you run stock comp, rebound clicker settings or is it trial n error set up !

[@rmatvmc]

Start with your stock settings and then go from there.

I have a 21 husqvarna 300 thx with spring forks. I also have a 21 KTM 300 Xc. I plan to sell the husky but I like the spring forks so I was considering swapping them. Any issues with that? Thanks!

[@wooodsryder]

How do you match the oil height for each side to be equal? Now with the spring there is more volume take up, does it matter?

[@adambrown6930]

Where can I find that exact same graphics kit on that bike?

[@rmatvmc]

This is the Roost kit from Attack Graphics. It has since been discontinued but one can still be made for you. Feel free to email [e-mail] and let them know you'd like the kit in this video and they can get you taken care of!

Many thanks ,very informative video. 😊

[@bayardoquintanilla4146]

Very nice congratulations

RT has a lot more spring options than 3. I count 8 on their site. Seems like RT has the most options for light and heavy riders of all the spring conversions. You need to get all the springs with their actual rate on your site. Soft, medium and hard makes this look like a B grade product. I don't really think it is.

If i have a kyb air fork and an 2005 kxf spring fork with inner tubes pretty damage.. both 48mm .. can I switch the tubes or the inside cartridge and spring to the air fork?

[@matthewjessop4987]

Is it only the one side needed for the conversion?

[@rmatvmc]

Yeah, just the one side. -Charles

[@1017cutlass]

Is there no clickers on that side now

[@wrenchone5003]

There is no clickers on the air side originally the clickers are on the other fork (dampening side).

[@joeybishop7604]

There’s no link for the fork cap wrench

[@rmatvmc]

The first link in the description will take you to a page with the Tusk Fork Cap Wrench. The part numbers for the wrenches used in this video are 1143530001 and 1143530005.

For 220 lbs ride RT says .89-.91, but you used a .92 for a 165 person? Is RT off or was the spring to high?

[@jcbenson01]

What did you find? Did you ever do the conversion? I’ve got two bikes with single spring conversion. One is RT and one is K-Tech and both are very soft in front and bottom easily. I think the companies started off way off base on their rates. I looked at the RT website calculator and it recommends a .97 for me @ 180 # B Moto.

[@leroywilliams7210]

I have the RT on both my bikes. RT calc said .89-.91 at time (I think they finally updated) and my other bikes in past were always.46 so doubled (1 spring vs 2) is .92. I bought .92. It’s a bit soft! I would go 1 rate higher. I left it as I have bad wrists and found it really helped with pain. I then did Max oil volume so that it ramps up faster and I lowered forks in the clamps as it was diving a bit. So it’s sitting lower in travel a tad. I should go up a rate but didn’t want to spend the $ and it’s been working with the above setup. For reference I’m late 40s, pretty fast and aggressive and ride everything from fast flow to slow tech.

[@jcbenson01]

@@leroywilliams7210 great info. Thank you. I agree. It seems like they updated their calculator along the way to recommend firmer. I dunno what’s in the bike now but I’m gonna try to figure it out and go up one rate. It feels good except for hard landings where there’s just no bottoming resistance and it bottoms too easy.

[@jcbenson01]

@@leroywilliams7210I could be wrong, but this makes sense to me: a two sided spring will require a softer combined spring rate than a single side spring since the dual spring setup also has two valve cartridges slowing down the travel. So I would think if I were a .48 on a dual spring, I’d need to be at least 1.0 on single.

[@leroywilliams7210]

@@jcbenson01yup, sucks I bought off their recommendation then too soft and now cost me double. Thanks racetech. Also, remember the oil height, makes a noticeable difference. If I remember the range is 525-575cc. I started at Min and was so soft I went straight to max. That will help with bottom out. Like adding Tokens in an MTB Fork.

[@jorgerenteria9421]

Make this conversion kit cheaper!!

[@sam-ww1wk]

Yeah, no shit...that should come with the bike in the first place. Air forks in mountain bikes have always sucked ass. Only made because they're cheap, and then sold has high tech light weight bogus crap.

[@dill_jle]

Air forks are shit
