Fork refurb

Two wheels good.

Fork refurb

Post by Hooli @ Mon Jan 16, 2017 12:04 pm

I'm refreshing a lot of stuff on my GSX14, part of that is getting the forks rechromed.

When I stripped them down yesterday I noted the bushes are rather worn within the fork legs. Will it make a noticeable difference to replace these? I've not noticed anything wrong with the front end previously, so unsure if it's worth the money to do.

I would. Tele forks are something of a mechanical abortion in any case, and you don't want any more wobble in them than you can help. I suspect that while you may not have noticed the gradual deterioration, you will notice the improvement from replacing them.

That's the thing. I've ridden much lower mileage examples of the same bike & not noticed 'owt. I probably will change them though, they do need doing judging by the wear.

Personally I'd do all seals and bushes while its all apart. Nothing worse than putting it back together and 500 miles later doing it again.

Seals I've already ordered.

Going to investigate ways of freeing off the compression adjusters too, they've only been seized for about 7 years now.

I know I'll be doing it again, this will be the forth set of fork seals I've fitted to it so far. But it's a good point, I shall price up the extra bits.

Well I've just written up a list of part numbers & placed my order. Those four metal bushes total almost £77, that's a rip-off. But I've ordered them anyway as I intend to put another 100k on the bike & I doubt the originals will last that long.

How much is the re-chroming costing on the forks?

£150 including return postage, which is a lot better than I expected. Getting them done here http://www.forksrechromed.co.uk/ as a mate who is a rather good HD mechanic & bike builder always uses them for his own & customer's bikes.

There is also nearly £50 of seals & dust covers on top of that & £15 of oil. Gets expensive quick refurbishing stuff properly. I'm not even going to add up the steering bearings, replacement yoke, fuel filter (£175!) chain + sprockets, threaded inserts for the cam cover bolts etc etc. I've let it build up & need to do it all at once now, still at least it'll feel like a new bike afterwards.

Doing a load of other bits too, like greasing the swingarm bearings. Just listed the bits I'm buying above. It needs it, it's had a hard life ridden all year & so on.

Surely there must be a way of installing an ordinary one for an ordinary price?

That's what I thought last time too. Trouble is it's a stupid shape & forms the mount for the in tank fuel pump too. There is a bodge about drilling a hole in the side to reroute the output of the pump, but that involves an extra hole in the tank & has a tendency to fall apart. Still they seem to last 50k, so at least it's not a service item. It's going to be fun when they stop making them though...

It's No2 in this lot.

Now you mention that mount bit I get the feeling we've had this conversation before :)

Does raise in me the slightly deranged desire to get a GSX1400 or other bike with such an arrangement myself just so I can pigeon it and write a web page full of swears describing how I did it.

Here you go Pidge, this is what the fuel filter looks like & how it fits. It's the black bit on the right.

So is this about it?

So 6 on your diagram is some sort of coupling that connects the pump input to the filter?

And there is also some sort of seal that goes between the top end of the pump and the hole where you can see daylight through the tube stub in your first pic, only I can't see it because the pump is the wrong way round?

Or is that totally wrong?

You're wrong :) It's upside down in the pics which doesn't help sorry.

That tube you can see through on the first pic is the feed to the swirl pot, it's linked to the back of the tank so as you accelerate the fuel is squirted back into that pot so the pump doesn't run dry. The teabag looking thing on the goldish pump is the pickup filter & sits in the swirl pot. The flow is then up to the filter (down in the pics) that silver bit you mentioned as a filter is the pressure control valve. The long black bit that holds it all together is the filter that blocks & the fuel output is what you marked as the return.

Anyway talking of forks, I finally got these rebuilt today.

Considering those bushes looked the same size, I could see wear but it didn't look like it'd affected the thickness, they've made a big difference. The forks didn't just slide together, they slid together & I could feel the bushes controlling the movement. Have a few pics.

Cleaning up the bottoms, as you can see I wasn't going for a factory fresh finish

The difference in the bushes at the bottom of the stanchions

Freshly rechromed stanchions ready to fit

Two rebuilt forks with all the important bits replaced. I've not fitted them as I need to get new pinch bolts for the forks as the old ones are slightly bent

Well it's all back together, running & just been taxed. MOT runs out on weds so that's worked out well...

Think I might have to go out on it tomorrow to see if I can remember how, before using it for work next week.

My word it's made a hell of a difference. There is no loss of line over bumps or any real feeling of bumps tbh, it just rides dead solid & feels excellent. It's like a new bike compared to before. I'm really surprised at the difference as it never felt bad before.

Put 207 miles on it today after just nipping out for a little bit, took about 10miles for the engine & clutch to behave properly after the lay up. It's all good now though, hence I stayed out so long.
