Lookin good, glad it fitted with no dramas, I like the top mount spacer idea. Let us know how you get on with the shock on the road and what settings you are using if you have them to hand, would be interesting.

Can barely walk at the moment never mind ride... Prolapsed disk in the spine.  Still, it looks pretty :)

I set all the rebound, hi/lo speed compression before fitting but damned if I can remember what I set them to... Somewhere around middle

Sorry to hear that, I wondered about your injury but didn't think it'd be as serious as that. Wish you a swift a recovery as possible. On the upside, it's a opportunity to fettle your bike so you have more to look forward to once you're back in the saddle  :)

I was concerned that my plan to remove the swingarm for a good scrub and regrease whilst i was at it might be a bit too ambitious for the back, but I was surprised and marginally alarmed that the nut came undone fairly easily.

I can ride.  But as the injury affects the left side of my body, I cant absolutely guarantee that when I come to a halt, i'll be able to put my foot down and support the bike.  I'm sure 9 times out of 10 it'll be fine, its that 1 time that bothers me.  sometimes when I'm walking the left leg decides its having none of it... always a laugh that one! :D

Am off work this week :)  maybe i'll take her out tomorrow

Yeah, take it easy but let us know how you get on. Reminds me of when I had to ride my bike with a broken collar bone, turning right was ok.... turning left wasn't.... journey took longer than usual  :lol

Pic of test fit with the swingarm off
All fitted :)

My photos not so great though

I can't get the c spanner onto the pre load, so resorted to old fashioned long chunky screwdriver and rubber mallet.

If you take out the upper peg hanger bolt and crack off the lower bolt you can push it to one side making the preload adjustment a doddle with the c-spanner...

Yes, as above - or you could try from the offside of the bike instead.

I could get the c spanner in, I just couldn't get it hooked up... I'll just knock it around, once it set it don't need to move no more

Faulkner 725lb
Dog Bones were 127.5mm (I think)

I'm roughly 85kg geared, plus I usually carry a load

Preload position 3
Rebound 13 out
Low Speed 13 out
High Speed 2 out

Took it for a ride today, only a 25 minute ride.  It immediately felt much better.  I didn't give it the beans, because the tyres are still fresh (I laid the bike up 50 miles into a new set).  Also because I'm not confident that the bolt I used for the top mount is really up to the job, it was a normal Wickes M10x80, not high tensile.  I'm going to replace it with a high tensile or Ti bolt for peace of mind. We did hit speed limit +/- 10% on some country roads though.

More importantly, I was able to assess my own ability to safely ride.  It was hard getting on the bike, it was hard getting off the bike, and in all honesty, it was hard transferring my weight around to properly ride.  So I think I need to wait a little longer.

On the plus side, the bike started first click of the button after a month laid up :D

Next job - adjust the clutch cable at the engine end.

Just a quick note to say mine's fitted and has a few hundred miles on it now. Currently running default settings from Jeff:


"Setting the high/low compression damping at 4 turns out from full hard on the yellow high speed adjusting nut, and 16 clicks out from full hard on the low speed compression blue screw worked well for me, and my weight. Rebound damping i have set at 16 clicks out from full hard, and that worked well, also.


Preload is set midway, I haven't properly measured sag yet but I've not bottomed out yet so it can't be far wrong. Running a 675lb spring, I'm a couple of pounds over 14st when fuller clobbered up.


Impressions are it's a very worthwhile upgrade, even though I spend 75% of my time on motorways the old shock was still bouncing around in a rather undamped fashion, things are nice and smooth now. I've also got EMUs fitted to the forks and I was wondering if they actually worked but it turns out the old shock was so bad it was masking the front. With the new shock I can actually feel the front working properly which is a bit of a relief.


Cheers,
Rob

Hi all. I am new to fazer ownership and I'm looking into carrying out the r6 damper conversion.
What is the reason why the r6 damper with the separate adjustments nuts/screws won't fit on to the fazer??

Welcome.
The shock's bottom mount is the same, but the top mount uses a 10mm diameter bolt whereas the FZS600 uses a 12mm diameter mounting bolt. 
The R6 shock's top mounting hole is only 30mm wide whereas the FZS600's top mount is 40mm.
Lengthwise, the R6 shock is shorter than the Fazer's, so you need different length dogbones.
Finally, the shock linkages / linkage ratios are also different, so unless you're 8 stones or less you'll need to replace the standard R6 spring with a heavier one.

Thanks for the info. I think was yourself who posted (on a separate post) two photos of r6 shocks and said that one wouldn't fit on the fazer "even with a hammer!"
Why won't that model shock fit the fazer (separate adjuster version)? I only ask as ive seen a few of those on eBay for sale? I would find a photo of the shock I'm on about but I'm on my phone and it's prooving awkward to post a photo!

Oh, that was Luke / DevilsYam's comment, and although it related to fitment on the Fazer 1000 it sadly appears to apply to the 600 as well.

1999 - 2005 R6 shocks have the circular bottom shock mount so the linkage mechanism to the swingarm is different from Fazers.

The 2006-07 shocks have the same bottom mount as our bikes, but the top reservoir layout (separate high and low speed adjusters)  forms a large body that interferes with / fouls the frame.  That was the version Luke / Devilsyam referred to in his hammer comment and probably the one you've seen on ebay?

The 2008-2014 shocks have a combined high/low speed reservoir (look for gold outer and blue inner top adjuster) and magically fit both the FZS1000 and 600.
Unfortunately these 2008 onwards units have become the rarest versions on ebay and are becoming more expensive as they can be adapted to other bikes including Bandit 600s & Suzuki GS500s (!)

Ah that's a shame. Again thanks for the info.
Just bought the right one from eBay. Does the different colour spring indicate what poundage it is?
Are you still stocking/sourcing the correct dog bones etc for the conversion? I'm around 14st kitted up so would guess I'd need to be up near the 700lb spring rate to keep the correct sag?

Yeah I'll have all the bits needed for a conversion 'back in stock'  :lol shortly, don't have a 700lb-inch spring, only a 675lb.  Send a message to Robbus as he's around 14 stone and from memory there's a 675lb spring on his.

Excellent. Any chance of a price list for the parts required via here or PM or email? Take it's just dog bones, spacer for the spring and the top hat spacers for the m10 bolt? Will be glad when it's on there as I'm getting tired of my fazer's wobbly rear end!  :-)

Mac1984 - i'm anywhere between 12-13st naked so probably between 13/13.5st kitted, plus carrying in the top box.  I used a 725lb spring.
Preload position 3
Rebound 13 out
Low Speed 13 out
High Speed 2 out

Cheers Dcurzon. I was thinking about 700lb would be suitable for me as I'll never have a top box or luggage but will occasionally take the missus out on the back. Maybe worth upping it to 725lb. What was the standard fazer spring rate? I know direct comparison can't be made as the r6 damper is shorter etc. I've PM'd kebab19 about getting conversion bits.
Can't wait to sort the saggy arse end of my fazer. Then I can fit the r1 front end I've got turning up soon!  :D

I don't think you'll be far wrong with either really. The 725 will give you more preload adjustability with the mrs.

Hi thanks to Kebab19 I now have a well sorted bike.
Well I think I do as I really haven't put much mileage on her just yet.
The few miles I have done made her feel a lot more precise.
I will have to fiddle and tweak her to get the best out of her but she doesn't feel so saggy now.
Biking is about the Journey NOT the Destination...

I'm going to fit my r6 suspension and dog bones soon. Is it a fairly straightforward job with it up on some paddock stands or do I have to remove the swing arm to do it?

If you have someone to help it's easier for the two fiddly bits - top mount and lining up dogbones with holes.

Don't use paddock stands, put her up on the centre-stand.
Have your new shock's compression / rebound settings in place before installing it.
Completely remove the shock linkage knuckle underneath, drop out old shock & insert new shock up through the swingarm hole. Attach the shock to the top mount.
Grease the shock knuckle linkage bearings and refit the knuckle to the frame / shock lower mount. Fit the new dogbones.
Tighten everything and then check all mounting points again.

My fazer doesn't have the centre stand fitted from when I bought it unfortunately. Bugger!

Do you have access to a pair of axle stands? Might do instead
