Me personally, I wouldn't have a problem using it with that dent as long as it wasn't going to leak oil. I've seen a mate use one with a much bigger crease after he got his straightened after a prang. It also looks high enough to hide in or near the triple clamp maybe? Sometimes you can turn the inner to hide it facing back on an angle towards the radiator.Well, I finally drilled out the bolts. Tubes are apart right now. However, I noticed one of them that I took apart first has a dent in the fork tube. I don't know if this is because I accidentally had it slip and hit the concrete (very plausible...) but that's very upsetting. I tried to be careful but it just slipped... Oily stuff.
all this work and now the damn tube is has a minor dent in it. UGH! What do you think I should do? (Ignore it? Buy a new tube? Give up on everything?)
EDIT: It's at the top of the tube. So, it won't leak oil from here. It's just a unsightly thing and less structurally sound but whatever...
Also, a little helpful hint for when you reassemble the forks. Wrap the sharp bits with glad wrap smeared with oil when you insert the inner through the seal so you don't damage it. I learnt the hard way.
