is this typical behavior?

[bargovic]

When i let off the throttle fully, and get back on i feel a jerk.  My chain is tight. ( to tight? ) and i dont know if something is wrong, out of tune, or if im just letting on and off to fast, tho ive tried closing and opening the throttle very slow and i stil feel the jerk, not as bad.

any insight?

[themaffeo]

i get this from my mustang as well (depending on what gear/rpm i'm at).  I think you'll get this behavior from any significantly powerful engine.

isn't that just engine braking?  :dunno:

[what?!]

hmm...i get that too...i thought it was because my chain's loose...

maybe it's a gs thing...

[bargovic]

Im not shifting at all, just closing the throttle - feel bump, then when i get back on and the throttle opens it bumps/jerks again and i here a clunk or a grab of some sort.

when i engine break via a down shift and let the clutch out, its feels simmilar, but a little smoother.

I just dont want to cause any damage to the bike. it got just shy of 1k miles on it. with a service at 600

I get that on my GS...  And just about every manual car I've ever driven. Your chain tension can lend to it though...  Check the chain...

Loose? Tighten...  

Not loose?  Try to be a little smoother on the throttle, use the clutch more often, or don't worry about it.

It's normal, even on a properly tightened chain, you are still going to get some driveline lash with the engine taking up the slack from a freewheeling rear wheel and chain.

thanks everyone for the input

Feathering the clutch is the only suggestion I can think of.

I'm almost positive this is a usual behavior from the GS Bargovic, I have the EXACT same bike as you do and I experience the same thing. I'm also JUST shy of 1000 miles (956) and I've put all those miles on it in 17 days.

This happens to me too if I'm not being smooth with the throttle input.  You can write it off to transmission lash.  Even though the transmission on the GS is "constant mesh" there is still slop between all the gears.

Good Luck!

In the MSC rode a 125 dirt bike. Now that bike had this bad. Mostly because you could do all of 8mph in first gear. So I learned to feather the clutch alot and I didn't look like I was riding a bull anymore.  :mrgreen:

check your cush drive gromets and check to make sure your rear axle is properly tightend, only time i felt that kinda bump was shifting rear wheel or warn out cush drive gromets (rubber bumpers)

Another way to understand what is happening is to put the bike on the center stand (engine off), select a gear with the shifter, then move the rear wheel by hand. What you see is the amount of play in the gearing, chain and sprocket drive that translates into a "jerk" when you get on & off the throttle. It's normal to have some play in any drive train. Chances are, any excess looseness will be due to chain being too slack and/or worn sprockets.

Significantly powerful engine? This is a GS!  :lol:  :lol:  :lol:  :lol:

WHAT?! I think I got jipped, My center stand I just bought must be short. My stand doesn't lift my rear wheel off the ground... /red wine is best

Oh, and    it is probably nothing to worry about.
