RPM Response?

[South East Rocket]

Got a question here.  I dont know what a GS 500 normal RPM response (maybe not be the right word for it:  the speed your engine reves up and back down).  My carbs were nasty and i had to get a few new parts for them.

We all know how CBR's Gixxer revs up and down really fast.   My bike doesn't.

Is the GS500 supposed to?
Is there something I can do to remedy that problem?

Check your cable and linkage for free movement.  

Also if both carbs are not in synch they will not return to idle quickly when you let off the throttle.

Also if you have a air leak it will cause a similar problem.

If its a stock US bike, stock carb jetting, it will have a tendency to hang on higher idle when warm. it will also not "snap" back when you roll off throttle. it will also not warm up quickly. This is due to the lean jetting and can be fixed (somewhat in the case of the snapping back of throttle) by proper jetting; 125 mains, 40 non-bleed pilots (for stock set up).


...and what he said above.

Cool, thanks guys...  I checked out the throttle cable and that seems to move easy.  Great!  Means i gotta start messing with the Carbs.
Hey!  Any remedies for carbphobia???

Just do it!  

The hardest part is getting the tank off - the rubber fuel lines can be a bear.  After that, the next pain is getting the rubber hose off of the bottom of the carb to allow you to get the bowl screws out (they may need an impact driver) to get loose, or a realy good philips screw driver w/ correct size tip, and the carbs upside down on the bench, w/elbo grease.

After that It's easy.  After you assemble the carbs w/new jets and washers, it's time to drill out the plugs (if there not already done).  This may require (depending on your experience) you to go to a shop and have this done.  It shouldn't cost but a few bucks.  Make sure they don't drill too far and hit the tops of the screws underneath.

Follow the recomendation for jet size for your year bike.

Pablo, when we do your carbs, we need to document w/photos and discription on the HOW TO MOD CARB section on your web site.
