SRAM Grip Shifters
Since my bike was new, it has been easier to turn the gripshifter when going to bigger cogs. The detents seem to have more resistance to shifting to smaller cogs. This isn't a big problem on single gear shifts. However, multi gear shifts to smaller cogs and more difficult to get right. With the extra effort required to shift, it's easy to get more gears than you want.
How to fix? bk

Can you tell us what model of gripshifter.
Normally when going toward larger cogs you are going against the spring so the mechanism is like a pawl. On the way back down you have to twist hard enough to disengage the pawl (harder detent) even thought the spring is helping you. There really is no way to change this as long as the shifter is working properly.
The reason that I ask about the model of gripshifter is that SRAM makes 2 completely different families of shifter, the Shimano compatable (also known as 2:1) group and the High performance SRAM Esp (1:1) group (X.7, X.9 and X.0) The latter group requires the use of a matching SRAM 1:1 rear derailleur. This latter group is very nice machinery and shifts in either direction in a similar manner. There will be a significant "clack" when shifting to smaller cogs however as the cable takeup spring is relatively strong.

A. Have you been lubing the cable as you're supposed to?
B. Multi-gear shifting in one move is not advised with a derailer bike.
C. If it's a serious problem, you might do better posting on the Mechanics forum.

Multi gear shifting is one of the specialities of the SRAM gripshift/rear derailleur system.
MTB riders like them because you can grab a handful of gears after unexpectedly bogging down in a slow corner.
Even Shimano allows at least 3 gears per push.

They are X-9 gripshifters. They are working properly and I recently recabled to accomodate new h-bars. It definitely has more clack shifting down the cogs but it takes more effort to get past the detents. I'm wondeing if the down detents aren't a little tougher to prevent the der spring from pulling a gear change.
One thing does amaze me. I can shift from 1-9 or 9-1 in one snap and it will be a flawless shift. Of course, there'd be no reason to do it other than checking out your derailleur tune. bk

If the change is noticable from before the recabling job, pop the cable window open and make sure that the cables went into the guide hole. You will find this when the shifter is rotated full forward. If the cable is not seated somehow, it may be dragging between the guide on the spool and the housing.
X.9's should feel about the same in both directions except for being slightly louder when shifting toward smaller cogs.

My X.9 grip shifters are as maddmaxx describes, about the same in both directions.

One more quick question. Are both shifters behaving the same?

Both shifters are doing the same thing. I am going to check for proper cable seating in the housings. I guess I should mention it is an EZ Sport and the new h-bars are 4.5 inches longer than stock. Yes, I got a lot of cable. The front has 4 ft. of cable housing and the rear is pretty close to 5 ft. This may be the problem. bk
