This is the install instructions for the Yamaha FJ-09 / MT-09 /FZ-09 / Tracer 900 Seat Slope mod parts sold at JK3D.us Click the images to see the full instruction picture.
If you are not familiar with DIY work on your motorcycle or have any questions, be sure to have a qualified mechanic do this install. The install is straight forward, but if you are not familiar with doing this kind of work have a professional handle this. JK3D.us is only responsible for supplying the parts and giving the guidance below, any installation issues outside the scope of this is the responsibility of the end user/installer.
Remove The Tank/Seat Mount
- Remove the Front and Rear Seat
- Using a 10mm socket and a 4mm hex wrench, remove the 4 bolts holding the seat bracket in place. (Note the tank will rest in place with the bracket removed, but I would recommend doing this with a low fuel load in the tank to make it easier)
- Remove the OE Metal bushings, and Rubber bushings from the mount. (Use a pliers if needed to help push the rubber bushings out, the metal inserts should slide out easily) Keep the rubber bushings if you need to return to stock, you will re-use the metal inserts in the next steps.
Insert the TPU Bushing
- Insert the TPU Offset bushings so the hole is aligned toward the bottom center. This should be easily done just pushing it through the hole.
UPDATE: From late December 2021, an update to the JK3D TPU bushing has been shipping, the new bushing has a flange on one side that is larger. Install it the same as below but with the larger shoulder toward the tank like the below image. If the TPU bushing you have does not have the larger shoulder on one side, the orientation does not matter.
Insert the metal Yamaha bushing into the TPU
- Push in the metal insert/bushing so the wide portion is facing away from the tank.
Place the Mount back onto the bike and secure the tank bolts
- Set the mount back into its original position and thread in the tank bolts with the 10mm socket. Torque the bolts to 7Nm
(Note : if the tank is close to full, lifting the rear of the tank may be heavy)
Place the mount shim under the mount
- Gently lift up on the tank mount that was just installed to give clearance for the shim to be put in place
- Slide the shim carefully under the mount, be sure to not push it too far or it will fall down under the mount and you will need to remove the mount to retrieve it.
- Nudge the shim so its aligned side to side and front to back with the holes in the mounting bracket.
- Insert the mount bolts and torque to 7Nm (or slightly more to compensate for the plastic seating on the initial torque) *TIP* : Use some Thread lock on these bolts as there is less threads being used and the general elastic nature of most plastics.
Place riser pads on the forward seat mount tray, and mount the seat.
In the package Velcro is already attached to the seat shims, and an extra set is included for any replacement, or if you want to place velcro on the High and Low positions. You will need to apply the Velcro to the seat tray in the location you want. There are 4 “Fuzzy” velcro pads included so you can use both high/low seat settings. I am using Velcro for this implementation so you can move the pads to the high or low seat setting easily.
- Prepare the seat pan surface, clean the area the pads will go with isopropyl alcohol or some cleaning agent that won’t leave any residue/oils. (Alcohol lens wipes work for this as well)
- Place it where the seat forward feet normally land, you should see marks from from where the seat has been setting. – Press down firmly for 15 – 30 seconds on the velcro pad to ensure it adheres well to the base.
- Place the seat foot riser pad in place on the fuzzy velcro and wiggle it back and forth to fully engage the hook and loop
- Tips for Lower Location – Place the foot with the little tab that extends out the front (toward front of the bike) against the fully forward seated portion of the mount area. This should leave the slanted nose sticking out facing the back of the bike and let the feet slide onto the top easily.
- Tips for the High location – Place it so the slanted face extends out toward the back of the bike a bit as shown in the pictures on the top food pad area of the seat mount. This will allow the seat foot to slide onto the shim easily.
- Carefully align the tongue of the seat to the mount and slide the seat down to lock the rear clasp. Listen if the velcro releases or the seat pads move. The comfort seat and the standard seat both have different clearances for the rubber feet and it may take some trial and error if the pads are being moved by the feet. I designed the riser pads to put pretty firm loading on the front of the seat to ensure it does not sink.
- Tips for inserting the seat – Look for when the tongue goes into the mount at the front, and firmly push forward all the way before pushing the rear down. This will let the feet go over the lower seat mount tray riser pads before putting a lot of preload/pressure on them. You should know when this is working as the seat will be firm up front, and when you unlock the rear latch it should pop up a bit.
Test the seat is in position on the pads. the nose of the seat should be firm and not move around, if there is a wobble or gap that the seat moves up and down at the front with remove the seat and make sure the foot pad is still in place. You may need to move the foot pad toward the back of the bike slightly in some cases so that the seat foot slides up and onto it.
If you need to replace the velcro or add more, Industrial or Automotive velcro from the hardware store will work for this.
- If one of the pads gets displaced after a while, it is generally because the foot pad didn’t go up onto the riser properly and was kind of squished along the front, so it eventually wiggled it forward. It can also be caused by the surface the “fuzzy” velcro is on was not adhered fully.
- I’ve tested add-on feet, stick-on feet, and the velcro pads are the most consistent, but it does require a bit of a delicate touch to ensure the seat slid completely over the pad. If I get reports of the pads moving, I may make a video regarding placement of the seat.
- Do not force the seat too far forward and compress the nose of the seat too much or the seat may lock into the “high position” in the rear lock! Gently, with the seat still angled up from the back(a few inches or what ever lets you slide the nose lug in), put steady forward pressure to let the feet slide over the pads, then push down on the rear to lock it.
- If none of these work (the comfort seat has much softer and more grippier feet and have given me more issues than the standard seat), you can also remove the velcro from both sides and use 3M VHB tape to semi-permanently place the pad on the pan. This will reduce the height of the shim about 1mm.
- And as always, msg me @ Support@jk3d.us if you have any questions.
