Fork service - part required

[Arfa]

I'd like to give the forks on my Fazer a bit of a service. Although they don't feel particularly bad or have leaky seals, they're never been done whilst I've had bike (done 15K in last 2 years) and I've got no record of them ever having been done (bike now has 28K). There's is a spot of suffice corrosion on one under the dust cap - could just be spring clip though. Either figured it's probably high time to freshen them up.


So found the guide below:http://fazerowners.yuku.com/topic/23188/HOWTO-Forks-Seals-Bushes-and-Oil#.VCK-a5RdX2o
But know a local and reputable bike mech just starting out with his own worshop whose quote me £60 labour. Just need to source parts.
He's recommended I stick with OEM oil seals. Are NOK seals just as good / any different?
I'd like to sort out shopping list of the other stuff required for the job. Should I go OEM for the other parts, or are they less critical?


2x Yammy oil seals, 4EB231450100.
2x Yammy washer oil seals, 36Y231461000 - do I need this too?
2x Yammy bushes, 4FM231254000. Recommended, yes? This the right part?
2x sprint clips, 26H231560000. Unbranded good enough here?
2x Yammy dust seals, 4EB231440000. I can only find unbranded ones in a kit with seals.
15W fork oil. any tips on what brand, or just buy cheapest?


Anything else I need?


Been hunting down parts on this AJ Sutton page:-

Standard oil is normally 10w.
I've got 15w in my forks and it gave a much more firm and stable feeling up front in comparison, but i'm 16 stone so it made sense for me to give it a go but if you're a lightweight then you possibly could find it too firm, if not, go for it.
At least you have adjusters on your forks as well, i haven't got any on mine.

That was actually a follow up question I had. I've read lots about people firming it up with some 15W (ooo-err!), but yeah I'm pretty lightweight (~11stone ish). So wasn't sure if this was the right way to go.

It really does firm it up quite a bit, but as i also have a top box and take the occasional passenger then it's exactly what i wanted.
If you carry luggage or passengers then i'd say try it, if not then it's a matter of personal opinion whether you will like it or not, especially as youre not that heavy.
Make sure you get the correct oil level too, there's 2 levels listed in the book as the 98/99 forks don't have adjusters so need more oil.
I swapped my forks for older ones so have no adjusters, but i'm more than happy with the way they feel anyway.

Why change the seals if they're not leaking????

It is most likely it's the circlips that are rusting under the dust caps, although sometimes the steel inside the seal can rust and bulge the top of the seal.

Unlikely to need bushes at 28K

I would just remove the fork legs and replace the oil. Any 10W or 15W is fine as long as it matches the recommended specification and fill to the level for the appropriate model. .

Remove the circlips and check them if rusty replace it or clean them, grease them and put them back. Other than that leave well alone
