Hi all!

So I've been running the 11S for a couple of months and have begun to bond with it now. I must admit it has took longer than expected with a number of adjustments to my riding style. It definitely grows on you. There are a number of minor things I don't like the bike, most of it subjective though.
One thing I'm not keen on is the throttle response. I find the throttle action too slow. In that I have to twist the throttle grip too far to get wide open throttle. It makes it feel lazy, and when you do get it wide open it really picks up and goes.
Coming from a Suzuki GSX1250 I just can't get on with it. Is there an aftermarket option for the throttle cams? I'd guess if wanting to only change one it would be that on the throttle grip or the one at the linkage point where it splits.
Thanks in advance!

Thank so for the quick reply Steve. Looks just the job if a little bit of a pain to fit. Not cheap for a small bit of metal though

I ended up ordering a schwabenmax fast throttle cam thingy. Fitted it on Saturday and it was easy enough. Can't say as I'm impressed with what you get for the money. It's well machined, but still needs a fettle with a file to get it to operate correctly. You have to drill a small hole in the original throttle cam which acts as a locating point for a pin machined into the insert. This needs shortening though as it catches internally when rotating the throttle.
I'm yet to test ride the bike due to weather and flat pack building duties, but my original throttle opening from closed to full was about 100 degree rotation. It's now just under 90. So exactly the result I was after. Also as the insert follows a ramp the low speed control and times when the throttle is only slightly cracked open shouldn't be affected.

I grew up with old British bikes and developed a love for the low down grunt that they give. I tried the Jap bikes; 2 stroke twins and threes; then the big 4 fours. Blistering acceleration to be had, constant gearbox work. But my heart was with the torque offered by the Norton big twins. Newer Triumphs were acceptable, the Buell fantastic. The compromise was the R1100S, owned now for getting on 15 years, my last bike. Age! I get the same feel from my 180 bhp diesel car, albeit more slowly.
You can not expect the same response from a R1100S ( circa 1995) to a Suzuki 4.

I'm interested in one of these too, let us know how you get on with it
Its not lack of power that is the issue, it's the ergonomics of getting the twist grip rotated to WOT that is the problem.
Attempting to go from cruising to WOT gives quite an exaggerated wrist position, or often does not quite get you there.

Went out for a ride finally yesterday, and I can say i'm much more happy with the throttle response of the bike now. As previously mentioned I'm not under any illusions about the bike being faster, or having more torque. It was purely an ergonomic exercise and it's worth every penny for me.
The bike now gives the kind of response I personally prefer with less wrist twisting action. That combined with a throttle wrist rest and its now pretty much perfect for me. I've noticed that rev matching on down shifts is now easier too, as again I don't have to twist the throttle as far to get the required 'blip' in engine revs.

A bit old this post - but have only today tried it out
I made my own though - easily done by using a cutout from a 2-inch diameter plastic tube.
With a bit of filing etc. it fits OK.
From the grip side drill a small hole and countersink it for a locating screw to hold it in place (this is for safety as you dont want anything rattling loose in there to jam the throttle open... )

Just my 2c - anyway nice to be back on 2-wheels - first ride this season - yay!

How are you finding your modification? Am still pleased with mine. It did exactly what I needed.

The mod works great - now I can actually produce a decent acceleration without having to change grip halfway through
So definitively worth it - especially considering cost (virtually zero) and speed - takes about 20 minutes to do.

Can you show some photos, as I am not sure how/what your mod is from the description above?

Thanks

I am putting in a new battery this afternoon - will try to take a few pictures and post them

cheers,
Steen

Picture:



The grey plastic at the bottom of the "channel" is the "mod". It is simply a bit of a 40mm plastic tube - cut to the appropriate length and tapered at either end. So it fits snugly in the "channel". I dont recall the thickness - but it should be enough to leave a bit of lateral guidance for the cable - just to be sure...

The arrow shows the location of the (very small) screw placed at the bottom of the insert to keep it in place.

Contrary to what i wrote initially in this thread - the screw is not sideways mounted but radially. Size is really small, so you need a 1 or 1.5mm drill bit and a very short screw.

Alternatively, you could glue the insert in place - though personally I feel safer with a mechanical fixture.

The difference this mod makes is quite astounding - the bike feels much "snappier" and its much easier to accelerate neatly out of corners etc.

Have a go - and dont hesitate to ask questions if there is anything!

cheers,
Steen
