Busa Shock Talk

[plowsie]

So people, been reading all the threads with recomendations on shocks etc and had a little chat with Luckypants, and decided that a Busa shock would be best for my weight.

Is there anyone who has fitted one to the SV before?

Can I do the shock change on my own or will I need help? I only have the paddock stand that hooks under the swingarm so guess thats out of the question to use...

Is it best to get the bolts that hold the shock in just incase they won't come off? As I see from a few threads people have had to bust the bolts?

Cheers for all input guys.

If you have a NWS or ABBA stand you can do it yourself very very easily!

[mister c]

This is how I did mine.

The bolts were very tight, but came out eventually and yes you can do it on your own. Good Luck mucker :)

[Grinch]

I think I could do a shock swap in my sleep now.

[yorkie_chris]

Bolts will be a little bit of a pain.

Anyway is the shock going to be suitable? The busa is sprung quite hard IIRC.

[plowsie]

@ Grinch - You can do mine then :D :lol:

Okay so anyway, we've established the fitting etc.

Is there anyone that has fitted a Busa shock, what are the results? Will it suit a porker like me (I'm assuming it will).

[Grinch]

Yep, I have the zx636 on and its a hard shock even for my 13 half stone frame. Softening it up and sorting the front forks has helped, but I have had a numb bum and dead leg a couple of times since. Never got that with the SV, though as it was dyeing I did feel as though my teeth where going to be punched out of my head some times.

@ Grinch - You can do mine then :D :lol:



You want to bring it here and I will 'advise' as I have a Abba stand with the swing arm removal kit so the is no weight on the shock.

Might take you up on that mate, is here, London or Pompey?

[Luckypants]

Plowsie is a big lad. He is quite a bit heavier than me and the ZX10-R spring was well suited to my weight (which is stiffer than a 636 shock), hence I suggested that the 'Busa shock would be best to support his weight. I'm not calling Plowsie fat, he is taller and broader than me so simply weighs more.

[Grinch]

Well that's always Pompey, as that is where the abba stand and all my gear lives. But I can get the bits to you if you need it. Though thinking about it, you don't need the swing arm kit to do this, I'm being silly. Any Abba stand or NWS stand will do, its just padock stands that will be no good.

Just as long as he doesn't loose the weight as that will make it to hard for him in the long run.

[Grinch]

If I remember right, your need. Stand Abba/NWS, breaker bar, socket wrench, torque wrench, sockets, 14mm and 17mm. Spanners of the same size help else the nut on the other side tends to spin. Oh and some grease as your bearings will probably need it.
And last gloves, as it gets bloody minging down there.

[Demonz]

Of course you can also just run a crate or block of wood under the engine and support it with a rope off the frame upwards to a rafter/tree.

[plowsie]

Stand Abba/NWS, breaker bar,
Haven't got those, got the rest.

[Grinch]

Haven't got those, got the rest.

As above, you got a garage and some ratchet straps?

[plowsie]

Garage yes, ratchet straps nope.

[DarrenSV650S]

You get good ratchet straps from halfords. That's what I use

[Grinch]

Yep, there cheap, just hang it off the luggage rails on the back.

[northwind]

The Busa shock is very, very stiff... I've got one out the back if you want to give it a crack Plowsie, but it's for big lad + pillion really, or huuuuuuge rider.

[plowsie]

Thanks for the offer mate but I've already won one on ebay mate. £52 its cost me. I'm around the 18 stone mark so in the large persons category...

[plowsie]

So peeps, gotta try and have a go at this tomorrow night. I've had the lights pop on in my head and thought, do i need the tri-linky bit for the Busa shock or will the SV be alright? Didn't bladdy get one with it. Doh.

Just gonna use a car jack under the engine and try and get hold of some ratchet straps too.

To the greasers - what needs greasing when I do it? And with what?

[yorkie_chris]

I believe the SV linkage is retained same as other shock swaps.

Since the 'busa is from similar era as SRAD, you may need to turn the bottom of the shock around. Not sure.

Take the triple linkage off, take the center part of the bearings out, rub around with a rag and paraffin to remove as much of the old grease (if any!) and muck as possible. Then rinse with paraffin, petrol, brake cleaner, whatever and dry. Use brake cleaner last as it evaporates quickly...
Then with a clean finger, work grease into the bearings, lithium complex, LM, general purpose, something like that. Get as much in there as you can then reassemble.

[Viney]

Never over pack a bearing!

When i popped my last shock off i used my paddock stand then lowered it onto a couple of axle stands under the foot pegs the strpped them to each other to stop them sliding off in different directions

One thing i would say is loosen the bolts BEFORE you put it up on stands of any kind. Its soooooooo much easier.

[yorkie_chris]

Yeah for a wheel bearing, these are moving very slowly in comparison so you can fully pack them.

[plowsie]

Cheers for the advice guys. I think I have a couple of old jacks somewhere that I could use under the footpegs, not a bad idea.

[Dangerous Dave]

It is.

[plowsie]

All in seems pretty cool if you ask me, much stiffer, adjustable compression on it, niiiiiiiice. Was well easy to get it as i stated that, they were my famous last words. Busa shock bottom is not threaded so had to go and buy a bolt. Need to take it to someone who has a torque wrench that will do 78Nm, Ady and me decided 50Nm then a half turn, it didnt go any tighter anyway, but just gonna double check things.

Cheers again Ady for all your help and thanks for the text Ape, soon as I read the message I lost my phone else I woulda text back.

Next weeks task - change the fork oil and investigate why my calipers are closing in on my discs :D

[yorkie_chris]

Buy a bolt?

What manner of bolt? The ones used in the linkage are not normal bolts.

One from Halfords, we did get one from B&Q but in the end we decided it was made out of cheese.

[Luckypants]

You would be much better getting a pukka bolt for your busa shock, I doubt that a bolt from Halfords will have the correct strength for the application. Y-C will give chapter and verse on the bolt required, but a bit of searching would reveal the part number needed for the bolt folks use for their ZX-x shocks.

Yeah, just had a word with Suzuki on the phone. The Busa bolt is a nut and bolt, so may go and pick one of them up to check, but, its 10mm longer so it's gonna be a waste of time cos that will just collide with the dogbones.

[Luckypants]

Yeah but there is the same problem with using ZX-10 or ZX-6 shocks, but there is a suzuki (?) part number on here for a shock bolt that does the trick. I'm sure it will work for 'busa shock. I'm too lazy to do the search myself :p

[plowsie]

Search done you lazy fecker (its me thats lazy really :lol:)

Oh and Chris, I have seen your posts on there about putting any old bolt in there, looks like my bike is sitting parked up until I can get that part :)

[Mr Speirs]

just use the Kwak one. its the perfect size.
you will have to order it as neither kawasaki rushden or corby keep them instock.
let me know if you do as i need one too :)

Okie pokie. I'm gonna order one now mate anyway, will only take me 10 mins to change over (he says).

[Mr Speirs]

Can you grab an extra one and I'll give you the cash for it? Please ol buddy ol pal :)

Shouldn't take long to swap it out. Undo linkage, undo bottom shock bolt, put new one in, redo the linkage. Ohh it sounds so simple.

It is. Ordered for ya me old china. £10.56. Thats £8.56 for you £2 for me :D (Only kidding)

[northwind]

We put a GSXR shock into Matttheloony's curvy, and used a Busa bottom bolt- just ground it down to size. Not ideal as the bolt's heat treated, but it works.

[yorkie_chris]

Re. heat treating and grinding, do it in small stages and cool it down in between.

For SRAD shock I can't remember what bolt, but you turn the bottom of the shock around t'other way so it doesn't foul the linkage.

[plowsie]

Its not SRAD, its Busa 06.

EDIT: That weren't towards me was it :lol:

[yorkie_chris]

I know. But have a look and see if you can do the same trick.

[plowsie]

Probs nothing, will check later though.

[yorkie_chris]

Indeed, though actually if the shock bottom isn't threaded you can't do much. But if you run into interference issues with the nut + bolt then it's worth a look.

I could be chatting b0llocks, but it's something to bear in mind when you get t'other bolt.

[plowsie]

A-thanky-you-a-very-much. Will keep an eye on it when I do it.

Yah. For some reason, he wanted a GSXR thou shock in his, turned it into a lowrider :D

Same happened with mine, after ****ing about with a few bits it fixed up :)

[Mr Speirs]

A GSXR thou shock on a curvy would have made the bike really soft. Its softer than the standard IIRC.

[northwind]

Yeah, it was short as well. Really not a good choice, but that was what he bought, so...

[plowsie]

Mine feels a bit lower.

[plowsie]

Right then, after a few adjustments of pre-load, compression and rebound I am a happy camper.

My only little niggle is I feel a little forward biased, and in the wet I don't like that too much, but according to my fanny bands, I'm not all that forward biased, so maybe its just me.

I feel much better exiting corners, don't feel I am squatting as much.
