converting1979 suzuki gs1000g from geardrive to chaindrive,What kind of rearswingarm?

[gsman]

Hi everyone!



How to convert a1979 suzuki gs1000g from geardrive to chaindrive,What kind of rear swingarm to use?

I was reading some time ago on some other place on the net that it should
be possible to convert a geardrive GS1000G to a chaindrive model and if I have
a engine intended for chaindrive,what else can be done to make
this possible?

In advance
Thanks.

Wow - that's a somewhat aggressive project. I would think the list of parts required would be extensive. Good luck....

To make it easier, I suggest finding a donor bike, GS 1000. It's only worth it if you find one for nothing or close to it. Then cutting that rear frame off and welding it on the G frame.
Not worth the labor at all, because you can build your G into a nice bike, or you can sell it and buy a chain drive bike.

There is reasonable way to convert from shaft to chain, or visa versa. Sell the shafty and buy what you want.

It would be far easier and practical to just sell the G and buy a chain driven model.

My question is, why are you considering doing this?

 

[hillsy]

The shaft drive swingarms are normally wider at the pivot - which means you can run a wider chain line than with a chain drive frame (quite a common mod done with KZ's).

But as far as what swingarm?, you need to measure the frame you have and hit Google.....

If someone, some time ago, somewhere else on the 'net thinks this is a reasonable thing to attempt, then they need to explain how they think so. You'd have to throw a lot of money and time into the project in order to utilize a few hundred dollars' worth of parts in a way they're not well suited for.

AND I had my first Suzukis (K50,A100,T350 and more in the seventies,always wrenching and making
adjustments on them by my self so as I,m now in my fifties I am not a newbie when it come to wrenching and doing
mods my self.Just to name it

I like the options with chaindrive that makes it easy to change the gearratio up or down.
And,I don`t have any of the GS 1000 models (current GS750E)at the moment but
there are a lot more G models available for sale than the 1000E that I otherwise
would find interesting to look at.
As I live in Scandinavia,(Norway)the prices of the few 1000E models available here are up to tree times
higher than the 1000G models.So if there was some easy option of just add some other
rear swingarm it could be some very interresting deals on the 1000G to look at.


By the way,Do you all know that Suzuki was headhunting chief engineer Ernest Degner 50years ago from german make
MZ for their big skills with twostrokes engines?

Some may not know this.

You will need more than a swingarm. You will need to re-engineer the frame to hold it, too, as the shafty swingarm mounts completely differently.

As others have said, if you want a chain-drive bike, get one. There is no practical way to convert a GS shafty to chain.

Not only the frame but the gearcase is different too.

Even if you pay three times as much for 1000E it would be worth just selling the G and buying the E.

Thanks!

Will leave thinking this project as possible for now.

+1 This is the only logical course of action

Why do you need to change gear ratios. Are you planning on taking the bike to different track configurations? You can change the ratio with a different rear diff ratio from another suzuki models with some modifications. You would have to look at parts fisch, but Suzuki made the Intruder, Madura, Cavalcade, Boulevards, GSX1100G and maybe other models that the diff internals may be close enough to work and have different ratios. I've seen people put GS mag wheels on Maduras before. Plus early 1000G models use an 18 inch rear wheel and later 1100GL models use a 17 inch. I wanted the tune fork style wheels on my G, it's a tighter fit in the swingarm squeezing it past the diff, but it will go in, then you could play with tire sidewall ratios.

What is wrong with the shaft drive?

Rick, I think your finger slipped when typing.

The G models had 17" wheels (not 18), the GL models had 16" wheels (not 17).
I don't know of any GS shafty that came with an 18" rear wheel.

The only exceptions that I know of were the 1980 850GL and 1000GL, which had a 17" rear wheel (later models had 16" wheels) and the 450GA that only came with a 16".
