Default Throttle spring is too heavy..what to do?

I've been having an issue with my 2011 throttle for a while and read another post that shows the Crampbuster as an option. This thing is a device that clamps onto the throttle and helps keep the throttle in place while using less force.

I'm trying to find a permanent solution that isn't an add-on.

I find that when I go for a longer ride the throttle creeps....the spring wants to close the throttle forcing me to grip it tighter. As a result I'm getting the effect of the death grip on the throttle side. I always ride with a very light grip and minimal input on the clip ons but the strength of the throttle spring is forcing me to tighten more than I want to in order to keep the throttle open where I want it.

Would a set of more "grippy" grips help? Driven D3 or others?

Anyone out there have this problem and found a solution?

I've found after fixing the "clicking throttle," cables being too tight (happens on every RR I've personally touched) that the throttle got a lot more reasonable. It's so common in fact that I thought it was a normal characteristic of the S1K's throttle.. It's not.

I have made a simple bracket to ease the tension on the spring.I have several prototypes being used,with excellent results,and the design is now finalised.I am preparing to make this bracket for anyone interested.Soon I will post more details and photo's showing the fitting process.
I brought this up in a previous thread but was let down by a local raceparts machine shop so have decided to make them myself.

IMO the throttle on my bike is easier to hold steady than on my 01 Gsxr 1000. I just kinda roll it into position and lay my hand on it and it holds pretty steady. On my gixxer, my speed would flucuate, not on the S1K however.

Yeah, the 2012's really are a world different from the older models. I got a chance to ride my buddy's 10' just the other day and I was pretty surprised with how much the throttle resisted.

I'm not mechanically inclined so hopefully this can be fitted easily!

Would this be an issue retrofitting the bike in terms of potential side effects to the throttle assembly or other?

Definitely interested...when do you expect to have something?

Thanks!

The hardest part is removing the airbox assembly.Fitting the bracket is then easy.No OE fittings are affected.

I am waiting for the aluminium to be machined then I can finish the brackets

We took photo's of a recent install which will be posted shortly
