Back tier locked up on my 94suzuki intruder wanted to know if it just needs gear oil

There is a drain plug on the bottom of the final drive. Look up Suzuki intruder forum posts and learn how much hypoid gear oil to refill with.

Hi, all model VS 800 from1992-2000 take the same amount of oil in the front forks, using 10 weight fork oil measure into a clean measuring device or mark the side of the oil bottle 413 mls, pour this caerfully into 1 fork, and the same amount into the other fork, 413/413 cm (3)

Any brand with API SJ, SH, SG/CFd - Ratings

the brakes are locking/binding and need replacing

does the clutch lever release "sharply" and snap back after engagement? then lean bike over drain about a quart of oil, take off access cover to clutch and check to see if you have any broken clutch springs. if thats looks o.k. you"ll probably need new clutch plates. a real quick check when you ride the bike smell the oil, does it smell burnt? if it does, the plates are probably no good.

Tire* -- I don't know if I would suggest doing this yourself, but try taking the tire off, (this requires you to jack the left rear *tire* off of the ground), and checking to make sure your brake is disengaged, meaning that neither the drums (or pads if it is the sport neon) nor the parking brake is still engaged. If neither are, you have a more serious problem on your hands, but if they are engaged, remove the drums and reassemble. Make sure your springs are in the right spot.

You want gear oil in it, 80/90 or 90/130. Anything in that range will work. Change it about once a year.

No adjusting is possible.
Slip can be caused by several defaults:
- Wrong engine oil ( SAE 10w-40 API SE or SF only )
- Weak clutch springs ( free spring length : 34mm ( 1.34in ) MINIMUM
- Worn clutch disk 2(internal teeths ) ( wear limit 3.15mm ( 0.124in ) ) This is the last disk, against the clutch center
- Worn clutch disks 1 (internal teeths) ( wear limit 2.62mm ( 0.103in ) )
- Clutch plates ( thikcness between 1.55 and 1.65mm / 0.0610 and 0.0649 inches
- Damaged pressure plate ( cracks round the spring holes )

To check the clutch parts, the right engine cover must be removed.
Take attention while loosening the clutch spring bolts!
Drain engine oil, and set engine into first gear ( this locks the clutch for an easy loosening of the spring bolts )

Hope it helps

the oil level is max upper line on the sight glass on engine/ coolant level is max at upper level of expansion bottle as to the gears from neutral first is up and the rest are down
