Clunky 6500 FD Shifting

I built up my first Geared bike about a month ago. Since then I noticed that I have to use a bit of force to downshift the fd and the movement isn't smooth. I have Ultegra 6510 shifters and a 6500 fd. Is this normal? I want to try and fix this problem myself but if I can't, going to the shop is no problem. Here's a video.

Looks normal.

Is the problem resistance at the lever, like it's almost jamming? If so, try holding the brake lever so it doesn't move sideways when you downshift.

If it's easier then, the brifter could be on the way out... I recoed a set of these; there's a post about it on the second page of the thread linked in my tag.

Yeah it feels like resistance, at first I was afraid the paddle would break off.

Yep, your springs need tweaking, I'd say... not for the faint-hearted.

But not as tough as a full overhaul.

Eh, the build was pieced together with a bunch of used parts. Just to hold me over until I have enough money for something new. I guess i'll just live with it. It won't fall apart on me will it?

what the hell were you watching? Sounds like a lifetime movie.

If there's a problem, it would be in the shifter, not the FD.

I think it could possibly be too much cable tension. If not then try shooting the shifter full of WD40 to loosen the hardened factory grease.

I was trying to use flickr as a hosting site but I couldn't figure out how to attach it here. Derp.

Even when there's no cable attached it still works the same, I might try the wd40.

It's noticeably harder to upshift and downshift the left brifter then it is to shift the right one. Even if I detach the cable there is still some resistance.

You can use a Tiagra 4500 shifter, or a Microshift 9 speed, as a replacement; these should be 100% compatible with your 6500 group.

What I think is happening is the return spring for the upshift (brake) lever is a bit shagged, and when you go to flick the downshift lever, both of them move, and the jamming is a result of both levers engaging.

If it's not all that hilly and you won't be using it long, I'd just stay in the small ring and cross-chain when necessary.

Not unusual at all for 6500 stuff. The small lever feels like it requires too much pressure to shift into the smaller ring and when it does activate the FD shifts RIGHT NOW. Seen this on many 6500's, not so much on 6510's which seem to be smoother. Not to worry, it still lasts forever.

The 6500s I just overhauled were cactus, stuffed, rooted, buggered.

Dead. Paid $10 (I can get some pretty incredible prices on old stuff, but that was a fair price for em).
