Author Topic: Suspension fitted the wrong way up?! (Read 4803 times)

Hi,

Is there any reason why my rear fz1 suspension would be fitted with the damping adjuster screw at the top and rebound cog at the bottom???

Just looked at the owners manual and its defiantly backwards.

Bought the bike from a main dealer with only 2000 miles and a good history.

On mine screw is at bottom and cog at top, have you maybe got an aftermarket shock fitted?

Have a look at R1 shock to compare. Upgrade

According to the FZ1-S/ FZ1-SA owner's manual " The shock absorber assembly is equiped with a spring preload adjusting ring and a rebound damping force adjusting screw." Preload is on the top of the spring and the rebound damper screw is below the spring (there is no compression damping adjuster).
Probably wrong but I can't think of any reason why you can't fit the shock upside down though- Ducati have the shock almost horizontal. It may even run cooler with the damping further away from the exhaust...

Agreed! Pics coming up asap...

I spied a thread on how you can fit a 2015 r1 shock to an fz1 pretty much like for like. Id order one now if I knew for sure it would work on a gen 2..
Its definetly the standard fz1 shock, pics coming up soon. Just couldnt get my head round it leaving a dealership like that..

As said they fit R1 shocks on gen2 with an adapter , my neighbour has one fitted with Satans adapter

Google it, loads of info

R1 shock option without adaptor

Yea thats the exact thread I found on the 2015 shock. I've been trying to look up spring weights etc to see if it will give the desired result and not just look sweet..
Ive also googled a lot to try and find one of these mysterious satan adapters. Havent been able to find a picture of one let alone a sales site unfortunately.

Have a look at the american fz1 site , you can get them there, think it's 04 to 08 r1 shock

Dustydes · « **Reply #10 on:** 14 April 2017, 01:36:37 pm »

I will ask my mate.

He is selling his Gen2 and was talking about putting it back to standard including shock.

That would be brilliant, much appreciated

I've got a Satan's adapter and 2006 R1 shock on my Gen2. Basically the 04-06 shock is fine for lighter weight riders (160-190 lbs with gear) and the 07-08 is good for 190-210lbs. The adapter does raise the ride height by about .5 inch which improves the turn in but makes it a little harder to hoist it onto the centre stand.
Richard (Satan) was working on an adapter for shocks from the flat plane engined R1s but I think it may mean relocating the Rec/Reg. Check out the thread at http://www.yamahafz1oa.com for more info.

Is it possible that the previous owner fitted or had it fitted upside down so as to make the preload adjuster easier to get to? Just a thought.

Hamos · « **Reply #15 on:** 18 April 2017, 08:55:45 pm »

Yep, it is upside down.
Will probably make no difference to the working of the shock, but would think getting to the adjusters would be more difficult.

tommyardin · « **Reply #16 on:** 18 April 2017, 10:04:42 pm »

Being a bit of a Numpty, would it not work in an adverse way with the mono-shock upside down, there must be fluid or a fluid/gas combination in there, surely gravity would have that fluid or fluid/gas combination on the wrong side of the piston, above in the compression area.
I am just asking the question as I really do not know, I do know that you can get USD front forks but they are designed like that,but I am not very hopeful that a set of RSU forks would work in the USD position and my thoughts would be the same for a mono-shock that is mounted the wrong way up.
Please enlighten this Numpty.

That's why they are fitted with seals.......

What would require the shock to be removed from a 2000 mile old bike anyhow. Unless to be replaced by a more upmarket shock.

Ok, fair enough

PaulSmith · « **Reply #21 on:** 19 April 2017, 12:17:58 pm »

That doesn't look to me like a shock that has only done 2000 miles.

clumptydumpty · « **Reply #22 on:** 19 April 2017, 08:21:52 pm »

Id be inclined to agree with all of you, no idea why a shock would be removed other than possibly an upgrade, or else to remove and resell an upgrade perhaps?? This would be my guess if I had to make one.
Also the bike is now closer to 4500 miles as it gets quite regular use. I believe the mileage to be genuine as I know the dealer and the bike had the original tyres fitted, old and squared off but not particularly worn.
I do find the ride harsh and a bit vague at times on the rear.
Thinking of going for a yss shock, don't really have the cash to blow on anything more expensive right now. That is unless any of you have something for sale??😀😀

slappy · « **Reply #23 on:** 19 April 2017, 08:53:59 pm »

Try puting it on right way round first, then see if there is any improvement.

clumptydumpty · « **Reply #24 on:** 02 May 2017, 11:42:05 pm »

OK, so here we go,

shock arrived to day and looks completely different.

has anyone spotted this before or does anyone know what the deal is???

To my untrained eye, the travel is longer, the spring softer, the dimensions of the shock body are different and it looks a lot newer than the 2007 shock which it was sold as.
