i have bike at my friends house stripped down for paint. i forgot to tell my friend not to mess with front forks when he paints it. so today i go over there and he tells me oil came out. i get the bike back on tuesday so im trying to figure this out now before i get it back.

dump out all the oil in each fork and add a tablespoon at a time of 90w oil or 80w90 gear oil until it does not compress all the way down under your own weight on each fork one at a time just dont have a clue why he would take the fork caps off
so basically i have to put them back on and put a tbs each correct? he told me he was trying to remove everything else so he can paint the bottom of the forks and the tripple tree
do it while there off do one at a time and add a table spoon at a time until they wont bottom out with your weight
agree, thats what i did
before i started i tested one and it bottomed out fast, i added oil in the top cap and retested till it wouldnt hit bottom
its easy to do and makes it feel more stable in the front
he prolly tried to seperate the top and bottom to paint the bottom then realised its a pain in butt
I must say my front end feels a lot better now with that mod thanks again blitz
I just ordered a set of fork braces from the UK why am I finding all these parts for our bikes over there but no where else my rearsets my 9.5 shock and now 26mm fork brace still can't find clip ons tho

Fork braces are excellent for these forks! Even better if you can find a short enough mtb shock with all the adjustments.
As for clip ons pbu sells some or you can buy some x1 style clip ons. They work great! For me,plus the clamps that clamps to the fork legs. All you to use the handle bars from a lot of full sized bikes.
hmm cool ill def check that out thanks swheels
Iv'e posted pics of my homemade fork brace/shock mount.But these pics should be a little more clear. Plus a pic of the x1 clip ons.....

I have to say although it's not pretty,that MTB adjustable shock on the front made a world of difference. Before i added the shock, under real heavy braking the frontend would dive down real fast.Almost feeling like i was gonna be pitched over the frontend. So you keep doing this lap after lap can wear you down a bit.LOL Then when i added that shock and got a setting i was comfortable with. No matter how hard i got on the brakes the frontend dived down nice and smooth. So smooth it really was hard to tell and could ride for hours doing lap after lap.And not feel any fatigue plus i got much better feel from the frontend. I guess the frontend was compressing slow and smooth enough. So by the time i was entering the turns the frontend was properly weighted and planted.
The x1 clip ons will move the bars up an 1/2'' giving a person a little more room.

Dam it swheels we need innovators like you I wish we were closer I'd have a track buddy to try new ideas with and make some good parts for these
Anyhoo did you drill a hole right through the lower tree or just drill and tap it and is there a model type on that roc shock I just got one I was gonna try on my 18 but used another one instead maybe I'll get on this project in about 20-30 days when the brace comes in from the UK lol it is already set up for what you got going on there so ill be golden just attach to the lower tree
I remember now seeing that before thanks again
Funny thing is I am doing all this to my daily x19 and then will need to do it all over again to my track bike but nothing like real world testing right
And by daily I don't mean I commute with it just the one I ride the most by the way

Ugh maybe not I guess that was another one I saw owell I'll just make this one work for me I'll use a shock with a singe threaded rod one one end and a open hole like a typical shock on the other like a front shock on a old gm car but for a bike that should work so I can just drill a single hole in the fork brace and use some urethane bushings and mount the top like you did that should work good here's the one I just got well ordered a few days ago

yeah for sure! I always believed it takes atleast 2 or more to develope a trackbike.
The triples that I used are from an x1. I had x6 wheels on my bike a long time ago. I suspect you could drill and tap the lower triple. The shock is a rockshox deluxe. I plan on doing the same to my x15 also.
Ok well I just realized I ordered a fork brace in 26mm so it really does me no good and wasted my money yet again because this will mount to the fork tubes not the lower part like I c in yours
So what did you use to fab that lower brace was it steel or aluminum I can figure out the rest
And you have different forks on that bike correct x6 I believe for the dual brake setup correct me if I am wrong tho
And if so are they 26mm or a different size the upper tubes not the lower
S, sup bro, got a few tubes comming for the rear and a tire for the pb, me and nate are gonna hit the school lots this summer
dragon, the uk, spain and italy are way more into bikes than we are, somehow 3hrs of left handers is more popular here

Yes the forks are 26mm and they are x18/x15 forks. Only the triples and clip ons are from the x1 styled bikes. I had to use the wider triples becuase the x6 front rims had wider axle hubs.. This in turn worked out perfect. Because when I went back to the x18 wheels. All I had to do was make spacers for the axle and brake disc. So this allowed me to be able to use bigger front discs.
I used aluminum flat stock 3mm thick and 1" wide and was 4ft long. Then used some right alum stock for the lower shock mount. Then I used a solid piece of aluminum that was 9mm thick and 4" long(from a pocketbike triple tree). And placed it in the center of the brace. This added extra strength plus as you can see in pics. I had bout an inch at both ends to put bolts to pinch the upper part of the lower forklegs.
The brace is a wrap around design and can be done without taking the bike apart.
Also I don't think you have to drill into the lower triple. you fab up a upper mount for thr shock to bolt to your lower triple. There is 2 bolt holes in them from the turn stops.
I used a drill,hacksaw and 2 pairs of vicegrips.lol

Cool good just as I though I will get started on that soon
I was glad you didn't say something like I found two small fence pole clamps off a gate down the street lol
I'll be going Dow to the local steel yard to grab up what I need thanks again

whaddup! I've been slowly working on the dirty girl. Been modding the x7 gas tank to fit on my x18. I'll firing her up soon this might temp me to go fot a ride.lol did you find a bigger lot?

Lol you know my style lol.
I'm gonna eventually fad up a bracket that bolts to the lower triple. That will allow for a longer shock to use. This should make it easier to find an mtb shock to use as an external fork cartridge.
Just bump....... I think someone was looking for fork brace ideas. Shhhhh it's top secret....lol
dang, knew you had posted pics of it somewhere... i just forgot where!! lol thanks


...these pics should be a little more clear.
Yes, yes they should be :D

Can you tell me how you made it? Did you just bend aluminum around the fork tube? I really like the idea of the bolt on ones i posted in the thread i started.
Yep just start off with a complete bend on 1 leg first then bend the alu around the other end. And leeave the front wheel bolted on. That way every thing stays lined up.
