83 gs750e build thread

[Rkt-Rch]

Hummm I've owned a lot of bikes and have many up over 140-150 and to say this bike won't go over 120 is @!$@# With a bad clutch last year I had mine over 110 in 3rd and still had 2 to go. And yes I was racing a Nissan Maxima and yes It was my maxima so I'm really sure it was accurate. And no I wasn't driving both at the same time !!

150mph can be done (down hill with a tailwind) LOL Lot's of mods are in order to get that out of a 700... Also If you put a light rider on it that would also help.

120 yes, but 150? not without some work on the cylinder head and some bigger carbs. I've got a 600 Katana front end and a 1100 gsxr rear wheel on mine and the wheels are a lot lighter than the stock stuff. The fork assy is about the same weight.

Im not certain that bike is capable of that speed, and if it is my concern would be stability. Have you ever gone 150 on a bike? It is a whole new dimension. I have done it several times on my FZ1, but have no desire to push my 700 to that speed on a set of bias skinneys. Good luck and be careful!

I agree. I've gone over 150 and these 750's aren't going to do it without a LOT of mods. The problem is that wall of air you've gotta push, it takes quite a bit of hp without a decent full fairing as you see on the modern sportbikes.

How accurate are our old gauges +/- 15 mph or more at top end?

[cyclefvr2]

well guys my cycle magazene says they did 131 mph factory!, im sure with some mods it would do it , compression is a big factor stock they only have 9.6:1
here are a couple pages for referance straight from those days
bikes these days have 12-14:1 easy
a big bore kit,and good cams would be sweet

[cyclefvr2]

here is a nother pic, i cant put them all on one sorry

[cyclefvr2]

pics for ya all

one more pic i have one more other than this

[cyclefvr2]

last pic

this is the last one, this is out of the service manual i have shows the compression ratio, and its low compaired to other bikes
maybe i can give the magazene lol its old has opages missing ,but it has the zuk in it still anyonw want it?, just pay the shipping n its yours

The difference between 131 and 150 is huge. Personally, I think you're underestimating the challenge, but by all means give it a try.

Most cars/vehicles have optimistic speedometers. They're built in by the factory so that you don't get a speeding tickets when traveling at the indicated speed. Have you tried using a GPS to validate your speedometer?
