As above really

I'm going to remove my forks to take to a bike mechanic to do my seals, put in decent oil, and maybe change the springs, just looking for some hints and tips for doing this please, and also what rate of oil should I put in them for my 10 1/2 stone with kit on but odd pillion on too.
Thanks.

15w instead of the advised 10w

hints on how to remove the forks??

I hung my bike from the ceiling

using 2 ratchet straps at either end of the bars, bike on center stand.. pull up until rear wheel is on the ground.. drop the front wheel out... loosen pinch bolts... what forks fall on you toe

Just got new Hyperpro springs in my front fork and on the rear damper. It is a complete kit, and its working very good.

Cheers Paul, I'll make sure i get the heavier stuff seems to be the way to go

Stevie, I'm hoping not to drop any of them on my toes, but I'll certainly watch out for it

Guessing, you can still drop the wheel off when it's on its centre stand? Provided it's supported with the straps as you suggest.

Seems a good set Bimbam, if only I could figure out their website, can't seem to search for the bike

Was your set for the fzs600-fazer? How much was it if you don't mind me asking?

Bimbam · « **Reply #6 on:** 20 June 2015, 06:18:13 pm »

Hi Sinto. I live in Denmark and got it from The Scandinavian dealer.
It is called a Combikit. : SP-YA06-SSC004. And the price was 2.100 Dk = about 280 euro.
It is like a new bike now

Cheers Bimbam,
That works out about £200, did you have to fit them yourself, was it easy enough?
Found this...

This is for 00-03, does anybody know if it's the same as the 98?

anutz · « **Reply #8 on:** 20 June 2015, 06:40:26 pm »

the more i read the more i think stick with progressives for our roads, but i am not sure, thats personal preference...

hagon and hyperpro do progressive sets that are stiffer than OEM springs and have seen good feedback on here about both

actually have my forks springs out now waiting to put a new pair in the next week.....

as for the oil weights, i am looking into that as well so cannot advise yet but i do think if you get a firmer spring you will need a different oil for increase the damping affects to match the spring - but someone may come along and tell me thats crap....

Found it on that site,
You can get loads for the 98 too
Oh dam these choices

Hi. it was pretty easy. Just read the manuel. Remember to mount the front legs 15 mm higer up. (it is in the manuel)
In my opinion, the small bumps are better than before and the big/hard bumps dosent rock the bike.

anutz · « **Reply #11 on:** 20 June 2015, 07:13:10 pm »

Sinto, yep, once its on the center stand you can then take the wheel out, then losen the fork bolts....

Did you strip yours down? Or just remove the springs, you weren't doing your seals were you?

anutz · « **Reply #13 on:** 20 June 2015, 07:55:32 pm »

i have tanken the springs out and drained the oil....plan to replace springs and oil not touching seals....think it might be tricky and they are ok for now....

Think that 15mm is just for the 00-03 models, can't see it for the 98-99

Bimbam · « **Reply #15 on:** 20 June 2015, 09:14:05 pm »

Hi. The 15 mm is printed on the front site off the manuel that comes with the kit.
Please be careful, when you chance the spring on the rear damper.

Ahh it comes with the set, I was looking at the official manual. Dint understand why they say to make it 15mm above though

In what sense? As long as you compress the spring using the right tools, should be easy, I've changed a spring before on my BMW, wasn't too hard.

I'm still not convinced to change all the springs at the moment, as it's actually just my seal on left fork that's leaking, wonder if it's worth waiting a month and doing the lot, as it's not a bad price, but I'm more concerned about no oil in front fork

15w oil, all day long, massive improvement with control, especially with passengers.

Paulfzs · « **Reply #18 on:** 21 June 2015, 01:47:02 am »

can someone give me a quick step by step on how to change fork oil?

like

1. remove caps
2. do this
3. put in xxxml of oil
4. put cap on

can i just take forks out undo the top bolt, tip it up to empty it then just refil?

Slighty undo caps while forks are tight in bike, pour the oil into a jug and replace with that amount ( for each leg ) or if you think it's too much less like when it's been leaking then use recommended amount. I go against the grain and never measure the level like most probably do, i just put the oil in and work the shock for the first 3 inches of travel to settle the oil. Just watch the spring, washer and spacer, if they come out then be sure to replace exactly as they were. And yes, use 15wt.

Paulfzs · « **Reply #20 on:** 21 June 2015, 07:20:41 pm »

so i can just undo caps take fork out turn it upside down but keep hand over it to stop everything falling out.

last oil change i did was around 5 years ago and i did the seals at the same time.

seals where only done on my bike around 4k miles ago.

maxzer1500 · « **Reply #21 on:** 21 June 2015, 10:27:43 pm »

No need to change seals if no sign of oil, even if dust seals are ok it's worth prising them up to make sure things are clean and dry underneath. You can lay spring washer and spacer on something clean, noting close coil end on springs and letting any excess oil to drip into fork tube first ( for the jug level ), i always use rubber gloves. Sounds a bit anal but i always clean the fork tubes of bugs after a ride, they are enough to make the seals leak.

Jules-C · « **Reply #22 on:** 22 June 2015, 11:08:37 am »

You have to take the springs, spacers and washers out to measure the oil level so no point trying to keep them in while draining the oil out

anutz · « **Reply #23 on:** 22 June 2015, 11:27:53 am »

any pointers on HOW to measure the oil level, if you actually pre-measured the correct ammount, could you not just pour it in?

Jamieg285 · « **Reply #24 on:** 22 June 2015, 01:07:11 pm »

You can't pre-measure accurately, only enough to get you close.

The actual measurement is done by measuring the distance from the oil level to the top of the fork (AKA the air gap). It's suprisingly sensitive, a little oil can make a big difference. You have a specific measurement to get to, but it's also important that both sides are equal.
