I recently purchased and Restored a 1980 GS1000G, as I have been fine tunning and taking it out for test rides I have found that in 5th Gear Im cruising at about 60mph @ 4,500rpm's. This gearing seems a bit low for a 1000 touring bike. I figured I would ask a bunch of GS lovin` Riders.

Does that sound right ???

Thank you.

Re: Top End Speed

I'm sure the 1000 riders will chime in with their rpm to speed, but in the meantime, I show 3500 rpm @ 60 mph on my 1150E. But then, I probably have 50 hp on you.

I'm at about 4k at 60mph. on my 1100.

What size are your sprockets?.
 
RPM

RPM

biggest complaint feels like it needs a 6th gear, the nice thing is you don't have to down shift to pull away, and you can load the crap out of it with the kitchen sink included my 1000 shows about 4,000 at 60 miles per
 
Top End Speed

As far as I know stock Gears. Im not familiar with gear ratio's on shaft drive as compared to my other chain drive bikes.
 
Since a GS 1000G doesnt have any sprockets, I assume youre asking me. :-) I think I'm 15/39, but dont hold me to it. Havent counted in a while. :-)

Thanks For the warm welcome to the Shaft Drive world.
I hear its Nice here. I'll check the Ratio.

Actually, I'm just stupid. Your information is fascinating none the less.
 
Snicker snicker :-) Where is my snicker smiley? :-)

Welcome to the forum. Final drive ratio is 3.09 Their is no practical way to change it. The last of the GK's had a 2.90? final drive if you can find one. The down side would be loss of torque the shaft drive bikes have. I usually run my 850 about 6K on the freeway & no I don't do 65. It will run all day like that

Thanks SqDancer That info is just what I wanted to know. And thanks also for the rest of the replies.

Im glad I found a good group of GS owners that are so helpfull. Any thing else you guys wanna add feel free. -Maximillian

Oh you wanted to know what shaft drives run at, doesnt matter your stuck with it :lol: :lol: Yea that was a shot at Leon, welcome to the nut house, were we use are old chains to whip them shaft guys when there in our way, Oh crap I better go hide my Yamaha,
 
Hummmmm, That old chain drive Dyno I'm on does 60mph @ 4000rpm.
BUT I have one more gear left 8)
70mph @ 4100rpm.

Yep Gee-sis is right, at about 110mph I start looking for that other gear.
I'm sure that other gear is on a 1200 Bandit.

I guess the Bandit would qualify well for that.

My sadly underpowered old shafty has such a difficult time attaining anything resembling high speeds. The necessity of inadequate gear selection can be really annoying, as when it gets above 110mph, you have to change up to 5th gear. :wink:
 
80 GS 1000G here and a hair below 4K rpm at 60 indicated.
you need to test your speedometer and tach, there is no guaranty that they are accurate, and ether one is most Likely lying to you.

SHAFTIES RULE!

PS: top speed is 135mph at redline
 
I'd have to agree with Leon - I'm running just under 4k at 60 ... 8)
 
Top End Speed

Yes!

I will check speed with my handheld GPS and see what it reads in comparison.

As for tach I have a tach/ dwell meter and it seems prety close.

thanks for the tip about top speed. You only know that fact because of math equasions right......... not from experience :wink:
 
speedo error

speedo error

When I first got my glz running, it seemed I was going much faster than what the speedo was indicating. INDEED, at an indicated 55, I was actually doing 65 as compared to a comparison with Julies Equinox. I cant speak to how close he speedo on the equinox is, but Ive never had reason to question it. Indeed, maybe a run with the gps is a good idea for you to check that speedo. For whatever its worth, the tach on mine doesnt work either, haha.
 
Considering how many different rear ends that oil seal cross references to in the thread about the 850 in Argentina, has anyone ever researched a rear-end swap from another Suzuki? Yamaha shafties almost all used the same rear end, from 650cc to V-Max/Venture. The guys at XS11.com found a useful drop in revs swapping in an XS750/850 final drive.
