How fast is is your old GS?

[cberkeley]

Got the GS650GL to 90 mph for brief periods, but my mind kept micro-imagining stress points on fasteners, rubber failure, metal fatigue and small animals appearing from nowhere. At that point my testicular will, would not allow me to peruse any higher excursions of the speedo needle. 90 MPH is plenty fast for this guy (my speedo indicates up to 140). The bike really grooves at around 65 to 75 MPH and I’m in this speed-range, periodically when I’ve got a clear stretch of open highway.

my 1980 gs 1000L will do every bit of 120,and is still accelerating,so i dont actually know how fast it will go.I do know until i let off the throttle, the kid with the loud honda civic could not get past me.

The speedo says 85 no matter what

Fast enough. But never more than 85 on the clock.

I am going to run both my bikes this weekend at Street Vibrations on the dyno drag machine. It won't show top speed, but will give me 1/4 mile time and speed, and horsepower at the rear wheel. Cool! I'm curious to see how the bikes do at this altitude (5000 ft.).

Top speed is cool and all, but anyone have any timeslips from the track they want to share? 1/4 mile - 1/8 mile - it's all good.


I ran 13.2 @ 99mph @ Atco Raceway, Atco NJ.
The clutch on my bike slips at high RPMs, so I can't launch hard and I can't shift fast. Once I get it fixed, I'm headed back to grab some better slips.

I did the Dyno Drags during the Street Vibrations event in Reno, Nevada. The '78 GS1000 did a 12.472 @ 106.5 mph. The '85 1150 did 11.439 @ 113.5 Not bad for high altitude!

sweet at any altitude I reckon... =D>

my gps said 124. something mph, I am not finished with the engine work yet and will regear when I am done

Really.. What have you done to the bike? With just one step richer jets, and a K&N filter I got clocked at 122mph on my 1983 GS550ES by an Illinois state trooper.

I have a V&H exhaust in the basement to install next year. I even have a DJ stage 3 kit I could install. ;-) It's tempting.

Hiway 219 Last Night 5:30 I Thought Is Would Just Open Her Up A Bit To See How She Ran. I Hit 90 Mph With Plenty Of Throttle Left So I Am Sure She Would Hit Well Over A 110+ But Id Didnt Go There Yet ??:-d

I have had my '83 GS650GD maintaining 115ish, I have taken it a bit faster a couple of times but was met with some moderate headshake, so I have to figure that out before I go all out.

I think/hope it was tire related, so with some new shoes we shall see what she can do .

my moped does 28.......

31 on a tail wind:shock:

Very cool! May I ask the b.h.p. numbers at that altitude?

I dont know what my top speed is due to the fact suzuki thought a 80mph speedo would be enought for an 1100. But I know that I can hit a top speed of 90 in second gear.

Does anyone know how I could calculate my roundabout hp or top speed from knowing what my top speeds are in 1st and 2nd?

The machine shows rear wheel horsepower, which I think is less than crank h.p, (b.h.p.). My best on the 1000 was 71.4, and on the 1150 it was 89.6.

As I understand it, you can note the speed at 4500 rpm in top gear and multiply by 2 to get a theoretical speed at redline (9000 rpm).

I've hit a 114 mph according to a gps on my 1980 GS 550E

140 MPH measured with an accurate digital speedo, chest flat on the tank at a secret northern Utah test facility* at around 4500 feet.
