How do I remove the seat lock to adjust it. It currently is in and will not lock the seat.

Replace the spring with a heavier duty should do the job.
Have you tried adjustments in the spring load to stiffen it up.
The rear shock on your Yamaha V-Star 1100 motorcycle assures that the rear wheel is always in contact with the ground and makes your ride much more comfortable by absorbing road vibration and shock while you ride.

But your shock needs to be adjusted for different riding styles, so depending on whether you ride fast or cruise slowly and how quickly you take turns, you may want to adjust the shock to get the most out of your ride.

1

Remove the passenger seat by loosening and removing the rear passenger seat mounting bolt with a socket wrench.
With the passenger seat removed, you should see two larger rider's seat mounting bolts.
Remove these bolts and pull the rider's seat off of the bike to expose the internals of the motorcycle. 2

Detach the quick-release clips of the ignitor unit found just beneath the seat using a screwdriver. Pull the ignitor unit up and to the right of the bike to move it out of your way.

Remove the mudguard quick-release clips in the same fashion, then pull the mudguard out of the bike to expose the rear shock adjuster. 3

Look for the small numbers on the rear shock adjuster.
On most 2002 V-Stars you should see the numbers 1 to 9 printed on the shock adjuster.

These numbers give you an idea of the current setting of the shock.
The higher the number, the stiffer the adjustment. 4

Loosen the shock by turning the shock adjuster counterclockwise to a smaller number using a spanner wrench.

This makes the shock softer and more forgiving when riding over bumps and uneven pavement, but will feel slower in turns and accelerations.

Tighten the shock by turning it clockwise to a higher number.
This makes the shock stiffer, increasing road response in turns and giving you a better feel of road conditions at the expense of comfort. 5

Replace the mudguard, ignitor unit, rider's seat and mounting bolts, and the passenger seat and mounting bolts.

Take your bike for a ride to feel the difference a turn of the shock adjuster makes.

The adjusting lever for seat position is not locking into place. On the bottom of seat are runners on each side with holes in them that the adjusting lever tabs will lock in and hold seat in place. The seat slides on the runners if those tabs are raised. There is also a connecting wire or rod from the lever to the other side of seat so when lever is pulled up, tabs on both runners are raised for seat to slide. Something is keeping the tabs from locking into the holes on the runners in your car. Maybe the adjusting lever is broken somewhere, or the wire/rod came loose, or the lever is just dry and sticky and needs a shot of WD40 to loosen it up. If you can't see it and fix it with seat in place, then pull the seat back off for the repair. Good luck. Post back if my explanatiopn is not clear or you still need help.

How to diagnose this problem ? Viewing wiring diagrams to see what all is invovled in these electrical circuit's , check power supply's an ground connection's using a DMM - digital multimeter !
What type power seat's ? does it have memory ,heated an cooled etc ?
Power Seats System Description and Operation
There are 2 options of power seat systems available in full size trucks. The first is 6 way driver and passenger power seats without memory. The second is an 8-way driver seat plus 4-way lumbar with memory, heat and optional cool function. While the passenger has 8-way power seats with heat and optional cool function. For the driver memory seat operation, refer to Memory Seats Description and Operation. Power seats without memory are completely controlled through the power seat switch. Battery voltage is supplied to the power seat switch through the power seat circuit breaker. While the seat adjuster switches are in an inactive state the switch contacts are closed to the power seat switch ground circuit. When a power seat switch is pressed to an active state the switch contact is closed to the battery voltage supply circuit. Each seat adjuster motor is controlled by the power seat switch through 2 motor control circuits. The seat adjuster motors are bidirectional and the direction of adjuster motor rotation is determined by which of the adjuster motor control circuits is switched to battery voltage while the other remains grounded.

If it has memory seat's there is a control module !
Battery voltage is supplied to the driver seat module through a 25 A circuit breaker. The driver seat module supplies the seat adjuster switch assembly with a battery positive reference voltage. While the seat adjuster switches are in an inactive state the switch contacts are closed to the adjuster switch common circuit.
Both right side windows have a seperate power supply from the left side window's ,has RT DOORS circuit breaker CB1 - 25amp. location left instrument panel fuse block . Circuit breaker's very rarely fail .Do the door lock's work on that side of the vehicle ? The windows won't work with their own switche's ?
The DDS controls the passenger window through a GMLAN message to the PDS. When a power window switch is activated in the up or down positions the PDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the PDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist, and during window motor operation the PDS continues to monitor the motor current to verify proper window motor operation. (Scan tool support is available for this system)
Check PDM fuse 4 15 amp ,this supply's B+ voltage to the DOORLOCK/WINDOW switch passenger side . Check for broken wires inside the flex boot from the body to the passenger door .

Adjusting your seat height ....
1) Locate your Lock Tab ,this will be located under the front of your seat.
2) Flip the Tab of your lock tab,this will unlock your seat and make it feel rocky
3) Lift your seat off the bottom part of your Jet3, set the seat right next to your Jet3
4) Locate the four seat Post,two in the front two in the back.These post will have at least five holes,the holes are your adjustment
5) Locate the four Pins,two in the front two in the back.These pins are in one of the five holes on the seat posts.
Now that we know where everything is .....
6) Pull the two front pins located on the front seat post,putting the pins in a bottom hole will raise the font of the seat ,putting the pins in the top holes will lower the font of the seat."the same goes for the rear of the seat''.
Adjust your seat accordingly....
be sure everything lines up when putting your seat back on ,also before driving make sure your seat is locked .. Happy Riding..

Depending on the bike model you will need to get the tank off. Open the rear seat, unclip the front seat. Remove the pipes from the gas valve taking careful note of where they go. Unbolt the tank front and rear.(Some tanks only bolt at the rear and to remove you have to pick up the rear of the tank, then slide it bacward) At the gearbox end loosen the lock and adjusting nuts and unclip the cable. Take note of the cable routing. Route the new cable before removing the old one. Unhook the cable from the handlebar. If you have an adjustment nut at the handle bar end turn it in completely before adjusting the new cable. Take up the slack at the gearbox end and lock the nuts. Then do fine adjustments at the handlebar end.

Hi, sounds like your "seat adjusters" are failing. These are the two round buttons on the sides of the seat unit/bassinette. There is a plastic pin mechanisim inside the round buttons that either wears down with use or can snap off. Either way the seat unit wont lock into replace until the seat adjusters are removed and replace with new one's.

Contact Bugaboo for local repairers or if your are in Australia there is a service agent called Karlisles, their details are at www.karlisles.com.au.

Hope that helps.

The manual lever to release the seat is supposed to have a spring on it to return the release lever to the lock position, if the lever does not spring back when you let go of the seat adjustment lever then you know there is a missing, dis-connected, or broken return spring.

If this is the case try putting the seat where you want it to be and make sure that the adjustment lever returns to the lock position, now check to see if the seat will lock in with the adjustment lever in the lock position.

If it does lock in repair or replace the return spring.

Make sure that the adjustment lever is attached to the locking linkage and it does move the locking mechanism.

If it still does not lock into place then there is something wrong with the seat locking mechanism, and some WD-40 sprayed onto the seat rails and track might release a stuck mechanism, and if everything seems to be working alright, and you can see that the locking mechanism in the seat rail is moving in and out of the lock position, then the locking tabs are most likely sheered off and you will need to replace the seat.

Also look under the drivers side seat and compare the lever position and the linkage connections with the passenger side seat, and make sure that it is all operating like the drivers side seat.

On W-Body vehicles, the front seats are secured to the floorpan by two front hook attachments and two rear bolts installed to nuts welded to the floorpan.
The manually operated two-way front adjusters provides only fore and aft movement of the seat. When the seat adjuster handle located on the front seat is pulled up, the seat adjusters unlock, permitting travel of the seat. When the seat is in the desired position and the seat adjuster handle is released, the seat locks in place.
A power operated six-way seat adjuster is available. The adjusters are activated by three 12 volt, reversible, permanent magnet motors with a built-in circuit breaker. The motors are energized by a switch bolted on the seat side panel.
The three motors drive the front seat and rear vertical actuators and a horizontal actuator. When the adjusters reach the limit of travel, torque is absorbed through the rubber mounted grommets located between the motor and the support. An overload relay is provided in the circuit and will open should excessive stall be applied.
The optional 60/40 split bench front seats have seat back head restraints on the driver's and passenger's seat back. The head restraints are designed so they cannot be removed from the seat back without first inserting a small rounded tool inside the head restraint support tube to release the locking tab. The 60/40 split bench seat is equipped with a reclining mechanism on both the driver's and passenger's side. The recliner lever is located on the outboard side of the spring cushion. When the lever is pulled upward, the spring loaded dual linear reclining unit located in the cushion frame is released, allowing the seat back to be pushed rearward or allowing the spring loaded reclining unit to bring the seat back forward.
Bucket seats are equipped with manual reclining mechanisms. An optional six-way power seat adjuster is available. Some bucket seats are equipped with inertia seat back locks. This system allows the seat back to fold forward without requiring the occupant to release a locking lever or access to the rear seat area. During a sudden stop or deceleration, or if the front of the vehicle is nose down, the inertia system of the seat back lock will engage, holding the seat back in its rest position. A release lever is provided to allow manual release of the seat back lock when the vehicle is in the nose down position. The release lever is located at the lower rear outboard corner of the seat back.
Some W-Body vehicles (notably Pontiac coupes) have passenger front seats equipped with an E-Z Entry device. This is actuated, in an unoccupied seat, by completely folding the seat back forward disengaging the adjuster, and sliding the front seat forward to gain access to the rear seat area. To return the seat to its normal position, return the seat back to its rest position, and slide the entire seat rearward, engaging the adjuster.
W-Body rear seats are available in several styles including a rear seat with an integral child restraint device.

Sometimes it just takes two really strong people to remove these seats. Especially if it is that old. I`m not saying damage the chair,but i`ve had some that were almost impossible to remove.
