1000G feels "sluggish"

[Guest]

I've never ridden another GS so I am not sure exactly how these bikes perform when running "perfect", but I feel as though the bike may be running a bit "sluggish". I know this thing is 40 years old and all, but I feel as though when I get on the gas, the RPMs start getting up there around 5 and 6 but the bike doesn't pull really hard. I guess the best way to describe it is that the motor seems to respond pretty well to the throttle, but the bike doesn't seem to really take off at any time...its completely stock to my knowledge, and the only thing I think might make the bike feel a bit off is the fact that the carbs have not been vacuum synched...

Should the bike give a pretty hard pull at hight RPM's? Or is it just the nature of these bikes, considering their age and the shaft drive that they aren't incredibly "peppy". It gets going pretty good, just doesn't accelerate too hard. Thanks guys..

Have you adjusted the valves? Verified the jets are stock? Freshly clean air filter?

Clutch slipping?

Jets are good and the air filter is nice and fresh. I know I need to check the valve clearances, I have just been putting it off but I know its important and I really should check it and just get it done.

-Regarding the clutch slipping...its funny you mention the clutch because thats kinda what if feels like, almost as if when the bike's RPM's get up there it feels like the clutch is partially being pulled in and not letting the gears and drivetrain rip free and unleash the fiery hell that is a 997cc motor

Yeah, try new clutch springs, it will work a lot better.

Okay, I will try messing around with adjustment first, the clutch doesn't let go until the lever is pretty far out, so I will try that. But I'm sure the clutch springs become a bit less springy after sitting compressed for 34 years.

They are just as strong and stiff, but they get shorter with time. New stock Suzuki springs will be fine.
