Fazer rear end

[dangerousdave]

Hi all,
i am in the process of changing the rear end on my 600 divvy (98) and have a fazer 600 (99 i belive) swingarm here. Only problem is its about 20mm too wide. Now ive seen one on here recently that had a fazer rear end, so my question is this.. Do i mod the swingarm, or have i got the wrong fazer arm? Nothings ever easy is it?
Thanks
dave

I have also thought about doing this but i was told it has to be an old fazer mk1 i think someone said.

[dangerousdave]

Hi, thanks for the reply!
Is a 1998 not a mk1 then? I only thought there were 2 fazer 600s?

Dont forget to account for the wider wheel which might put the sprockets out of line.
A spacer on the gearbox sprocket could fix that if the frame doesn't get in the way.

Maybe the answer is to cut the frame cross tubes, loosen the rear engine mount and spring the wider swing arm in. Then weld in spacer tubes and suitably pack out the rear engine mount. We are only talking about 10mm each side so (although drastic sounding) this might be the easiest option.

[dangerousdave]

Theres about 15mm between the chain and frame so sprockets should be ok?
I didnt really want to start cutting up the frame either but mabie it is the easiest way?
Any other ideas?

[dangerousdave]

Ive decided to leave the frame and swingarm alone for now and see if i can find any other swingarms that might be a better fit, Ill let you know how i get on.
Thanks.

PS. Also i need ideas for getting round the dogbone suspension setup fazers use? Might just weld a mounting point onto the swinger?

[CD]

15mm frame clearance is fine with the std wheel. I was thinking that the wider wheel will need the engine sprocket setting out to bring it in line with the wheel sprocket and then the frame may well not be wide enough.

[dangerousdave]

yeah hopefully the chain will be ok, i can take the swingarm into work and get it to fit, but unless i can think of something to sort the rear suspension i dont see the point. Looks like the divvy with the fazer rear end (in the for sale section) has kept the standard 'shock bolted to swingarm' method?? no dogbones??
Man i wish i could speak to that guy...

You might be able to find a swing arm from the later FZ6 Fazer, which doesn't use a linkage and has a 180 section rear tyre.

[dangerousdave]

I think a 180 rear would be a little too big, sprockets wouldnt line up unless i took a lump out the frame for the chain... a160 rear should clear the frame.
I think i might be able to use the center stand mount for the suspension linkage, but do you think it will be strong enough to withstand suspension forces?

[bobh]

Thinking of sprockets, if memory serves the Fazer uses a 530 chain, though I think you can get alternative 520 sprockets that would be compatible with the D6 width.

As to using the centre stand mounts for the suspension, I doubt they would be strong enough. If you look at the leverage ratios on the links the mounts need to be capable of carrying (at a guess) 4-5 times the load on the rear wheel, i.e. quite a lot more than the centre stand mounts are designed for.

[dangerousdave]

Ohh well, i didnt think the center stand mount would be able to take the abuse, guess ill just have to bolt the shock to the swingarm.
I will look into the sprockets, and let you know how i get on.
Thanks, dave

i dont know if youre aware of the fact that an FZR600 rear wheel will fit straight on. must be 91-93 though as they are 4"x18". it saves having to change swingarms etc. also some guys have put in a 17" bandit rear wheel with some slight mods to be able to use modern rubber. just an idea. also the complete front end of an fzr will also fit, assuming that your forks are 41mm. if not, you will need 41mm yokes, which i have.

[dangerousdave]

No i wasnt aware of that... but i wanted to change the swingarm anyway.. standard ones ugly
Are the 41mm forks the ones with twin front disk? Will i need a 'complete' front end? (forks, wheel brakes) or will the divvy wheel/brakes fir the fzr forks?
Thanks for the info!

I think you'll need the whole lot. I believe the caliper mountings are all different between the three alternatives (early D6 single disc, later D6 twin disc and FZR) so it's tricky to "pick-and-mix".

I really wonder if you might not be better off just buying a Fazer rather than trying to turn a D6 into one?

[dangerousdave]

Looks like ill be buying an fzr front end then..
ha yes i did think that, i was knocked off it (the divvy) last december so i decided to make a project out of it. My other bikes a bandit

[CD]

You will need the whole FZR front end including wheel and fork yokes.

Then you'll have a tyre missmatch so it will need the FZR swing arm.

Then you have the problem that the rear sprocket wont line up with the Divvie engine sprocket (wider wheel) . So you'll have to find a way to space the Divvie engine sprocket out another 10mm (or more).
Then the frame wont be wide enough so you'll have to cut-n-shut the cross braces and fit spacers into the engine mount.

At least if the swing arm pin is the same, the FZR swing arm will fit without mods.

The last snag will be the Divvie 600 engine wont keep up with the FZR brakes steering and tyres.

Why not just buy an FZR 600?

[dangerousdave]

Mabie ill give the front end a miss then, unless i can pick one up on the cheap.
Im only 'doing up' the divvy because i already had the bike and lots of bits, so it is going to cost me naff all (£65 so far) and wheres the fun in just buying an fzr? i like a challenge.

[CD]

If you want a real challenge do something right off the wall
Hydraulic transmission no gearbox or maybe one with direct drive plus hydraulic.
Clean 2 stroke - direct injection petrol using car GDI parts.
Diesel (no not a silly generator engine)
Hossack suspension

Something that's not been done before.

[dangerousdave]

ha i dont want that much of a challenge
Fazer swingarms in now anyway so ill get some pics up when the rear wheel/sprockets are sorted.
