Throttle issues

I went out to see if my clutch cable replacement worked.. It did thankfully and I got on and started her up and every time I give her throttle the Rpm drops and she cuts off. I tried again with it in 1st gear.. I let the clutch out into the friction zone and then the bike got moving and I let the clutch all the way out and she cut off again.. Anyone ever have this issue? If so I'd really appreciate some help

newbie1993

I was told to adjust my cable.. Hopefully that'll help

Still no replies.. Well that sucks.. Still lost

Err ... One thing I can offer at the moment is the clutch safety switch and side stand safety switch combo ... A possible wiring snafu in there? ..

Clutch switch is for starting the bike .. Ie .. Hold the lever in to be able to start it

Side stand switch is to make sure the stand is up and out of the way when you in gear

... A mix of the wires somewhere ? .. Not sure it's even possible but?

.... But when you moving off , enough throttle? ... Is it a sudden chop to engine power/stop ... Or does it putterputter and cough stop?

newbie1993

It's a sudden chop to engine cutting off.. It's like as soon as I'm past the friction zone rpm drop and rapidly from 2-3k down to 1-1.5k

The rear wheel gets rolling before it does too if that makes a difference in diagnosis

Just so I'm following, you're gradually opening the throttle as you ease the clutch through the friction zone, right?

I find that on my GS I need to rev to 2.5-3.0k rpm before I have enough oomph to really start moving and completely let go of the clutch lever.

I wait till I'm rolling a little then I gradually open the throttle.. Is that wrong?

Shouldn't be a problem as long as you're rolling on the throttle before dropping the clutch completely. Have to open the throttle to get your revs up if you want to let go of the clutch is all I was really trying to say. If you are slightly moving via friction zone but let off the clutch before rolling on enough throttle, you're guaranteed to stall out.

As I understand it, if you have the 2-stage carbs from the 90s model years versus the 3-stage carbs of the 2000s, you have to roll on more throttle just to get moving out of the friction zone. Mine is an '07, so I can't really speak from experience on the earlier GS models.

Just remember, as long as you've got good clutch control, you can rev the heck out of your engine without worrying it's going to take off from underneath you.

I've definitely gotta work on clutch control.. I'm gonna give it another try..

Not sure where you're located, but if in the USA, I'd definitely recommend taking a Basic Rider Course by someone teaching the MSF's BRC curriculum. They will help you with the basics, especially clutch control and the slow speed maneuvers that translate into more solid higher speed skills.

The one I took but didn't complete sped through the curriculum.. I'm just gonna get my permit and practice in a parking lot. The only thing I had trouble with really is not stalling the bike out... Everything else I'm really good at

The GS needs revs to roll. You must control the clutch and let it out smoothly and evenly. You rev it to about 3-3.5k and then begin letting out the clutch, while keeping the revs steady at 3-3.5k. You will have to give some throttle to keep the revs steady at 3-3.5k as you let out the clutch.

If you aren't used to it, revving to 3.5k seems like a lot. Especially with how much you turn the throttle on a stock GS. But really, 3.5k is nothing at all for the GS and its clutch or its throttle. Examine how far you have to move the throttle before its wide open, and look at how far redline is on the tach.  Don't be afraid to wind it up, you aren't going to hurt the clutch or the engine or anything on the bike... You just have to let out the clutch gradually and evenly. Don't let go of the clutch or release it quickly(aka popping the clutch) so that you don't take off too quickly and grab and handful of throttle you can't handle... Yet.  ;)

The first bike I ever rode was a Honda Nighthawk.. To me it didn't take that much rev to get it rolling maybe that's why I don't rev my gs that much. More revving and it won't stall out on me.. Got It! Thanks hopefully that's the only issue
