Okay, I'm confused
You can reach redline in top gear, or not?
If you're going 80 in top gear, it's redlined?
Can you redline it in any gear while you're riding?
What do the plugs look like? Post a picture1978 GS 1000 (since new)

1978 GS 1000 (parts)
1981 GS 850 (anyone want a project?)
1981 GPZ 550 (backroad screamer)

Ditto on the clutch!
Sure sounds like a slipper of a clutch!
High speed/high revs is pretty typical place to see 'em slip ona GS.

Different wet clutch. C'mon Dave! Give us a break! ;-)Originally posted by Dave8338 View Post
Don't worry, the guys just blowing smoke.
So what you're saying is going down the road at 80 MPH you tach is redlined? Either you're in third gear or you clutch is slipping BIG TIME!!!
Either your clutch cable is adjusted too tight, bad clutch springs, worn clutch fibers or glazed clutch steels or E all of the above.1983 GS 1100E w/ 1230 kit, .340 lift Web Cams, Ape heavy duty valve springs, 83 1100 head with 1.5mm oversized SS intake valves, 1150 crank, Vance and Hines 1150 SuperHub, Star Racing high volume oil pump gears, 36mm carebs Dynojet stage 3 jet kit, Posplayr's SSPB, Progressive rear shocks and fork springs, Dyna 2000, Dynatek green coils and Vance & Hines 4-1 exhaust.

It's all in the perception
Mr. gsx/gs biker,
Perhaps your tachometer or speedometer is not reading properly. The gauges do go bad sometimes. My speedo would dance around all over the place, reading 85mph with the tach at only 5000 revs (which should be 70mph). A little cleaning, a little lubrication and it worked much better.
Thank you for your indulgence,
