The best free Scrambler modification or your money back!
So I'm riding to work yesterday and as I'm accelerating over some washboard asphalt I realize I'm getting jerked all over the place. Most might blame the suspension but the majority of this motion is the fault of another component and it's easy to fix. The Scramblers come with a rubber isolated stem designed to filter out engine and road vibration but unfortunately it just flexes back and forth. This motion makes throttle application difficult as you inevitably roll it on and off as you are being jerked around.
You start by removing your instrument cluster. Three allen head bolts removes the front cover plate exposing the connecting harness. There is a little button down the left side on the harness, pushing it in allows the locking lever to rotate around releasing it. Put your cluster in a safe place so you don't damage it. I also placed a thick blanket over the tank to help protect it as you will be laying the handlebars on top shortly. go ahead and remove the four stem bolts being careful that your handlebar doesn't spin down and ding anything, place it on you protected tank. You now have access to your stem mounting 8mm allen bolts. Use a 15mm wrench on the bottom nuts as you break the bolts free. keep the bottom two washers and nuts for reassembly.
Pulling the stem bolts out you will find two small washers under the stem, dispose of these (not needed). You will also notice how the underside of the stem's mounting points protrudes from the rest of the stem. These need ground and filed down to be nearly flush with the stems bottom so it can then lay flat on the top plate. After filing these down go ahead and place your stem on top of the plate checking that it rests completely flat against it. If so start reassembly running the long 8mm mounting bolts down through the stem and plate. I apologize for this next part as I didn't take a measurement of the two additional washers I added to the bottom side ahead of the original washer and nut. They need to be thick enough (approx.1/8") and the center opening large enough to slip over the rubber portion allowing full metal to metal contact bypassing the isolated center section. The washers are pictured after I hit them with some paint as I had to enlarge the center section.
Secure these larger washers with the original nuts and washers and tighten everything down making sure that the stem is centered as you tighten. Sorry But with decades of experience I go by feel so no torque specs given here. Reattach your handlebar making sure all control lines and wires are run properly and finish up with your instrument cluster. Once you power up you will notice your clock and trip meter have reset to zero so go ahead and set your clock. Your odometers total mileage will read correctly.
After I did this modification I took my Icon for a long back road blitz which had lots of twisty undulating roads. I was amazed how much more composed my bike felt, night and day difference. There is no detectable increase of engine or road vibration and a lot less monkey motion in the handlebars. Hitting washboard is way better now that the bar has a fixed position, none of the unwanted roll on throttle as before. Everything from acceleration to braking is now immensely improved, I don't feel like a rag doll anymore. I would love to hear feedback as members here try this for themselves.
