fix bent forks

Before everyone fills this thread with "replace them" id like to know if its possible to fix slightly bent forks. i was in a front end wreck and my forks got bent along with my front wheel. the forks are not leaking so i'm thinking its not to bad if its still sealed. there are no creases or gouging or fork oil anywhere. so to save $3-400 bucks would it be worth fixing for now to get it up and running and replace later? and if anyone knows of a shop around the houston area that does this kind of work let me know.


CLIFF NOTES
Got in a wreck
forks are slightly bent
on a budget to get it moving
Fixable?
price range?
no leaks or crease
maybe minimal bends
thoughts?

can get pics if y'all need em

thanks ahead of time!:toocool:

Fixable? Yes
Price range? Free(ish)
Thoughts?

That being saidI doubt any reputable shop would do it as their garage liability would not cover such a crude repair. That being said, its just a piece of metal you can bend it back in place yourself. However, you will likely encounter serious problems with seals not sealing properly as they are made to be very exact and that coupled with the weakening of steel associated with bending that puts you at great risk riding considering the amount of pressure exerted on forks. You would also likely mar the forks without proper equipment doing it yourself creating further problems for the seals.

TLDR. Its really one of the worst things you can do to a bike.

Disclaimer. This is all opinion and conjecture and others opinions may vary.

another thought could the inner tubes just be cocked out of place? and not actually bent? like the impact just knocked them out of alignment?

nope. how do you know that it it's your fork leg that is bent? and do you know if it is the inner or outer leg? (if so, how do you know?) what specific things make you think your forks are bent? how did the accident happen? There are alot of other pieces to the 'front of a motorcycle' puzzle.

It's actually pretty hard to "bend" the tubes. Take them apart and roll the tubes on a flat table and you'll see if they are bent. I'd look at the triple tree. You can bend that by hand if you take it off the bike and insert the tubes. My kid piled me GSXR1000 right square into a fire hydrant at over 40mph and only the tree got twisted. We straightened it out in a vice.
Just a thought..............

Fork tubes can def be straightened as long as there isn't a crease. It takes a press and special fittings that go over the fork tube. Plus the forks have to be taken apart. If you have all the tools yourself and knew how to do it I would say go for it. If not. Just buy yourself a used set. It will be less hassle

it is difficult to get metal perfectly straight once it is bent, especially a tube.

Buy a new bike...
J/k I'd say buy some cheap used ones for now prolly a faster turn around any way.
+1 on the maybe it's another part not the forks I'd disassemble and measure as best as you can and refer to a manual to see exactly what's bent.
Besides metal just gets weaker and weaker the more times you bend it, most of the time.

for potentially bent or out of round long parts, if you cant tell visually, just roll it on a flat surface like a garage floor or counter top.

I dont think you need those thing to confirm they are bent. Should be easier to tell if they are off the bike. Find something you know is straight and see that way.

I read somewhere that if your bike goes down, you should loosen the triple tree and let the forks 'naturalize'...they may just be cocked up/tensioned as others have mentioned.

Based on the pics they ARE bent. Pretty obvious, and that is in the pics.

Replace them...

I bent the forks on my F4i years ago.. the guy said "yeah I can fix them np.. then after he took them apart they were bent worse then he thought... He told me "you can ride on them for a while but I wouldnt go fast and buy new ones as soon as you can" I was real skidish at first then after hitting 120+ or so once or twice I didnt feel anything wrong whats so ever.. I checked for leaks the first two months with no leaks and said it.. 5 years later they still work just great.

just my 2 cents
