Check the fuel filter and if it has a breather pipe on the tank, check it isnt trapped or kinked

1996 suzuki 750 katana engine shuts off when put into gear

Check your sidestand switch. It might think your stand is down so clean it and spray with WD40. Road grime and corrosion gets everywhere :(

Just put a new battery in and the bike starts great and runs great but when I put it into gear it dies (yes I am using the clutch). Tried to give it a little more gas before putting it into gear and it...

Okay.....I think you have a sidestand switch problem.
Do you notice that if you leave it in gear after it stalls....that even with the clutch in it won't crank the starter?
The sidestand switch is a plunger that presses in when the sidestand is down. The interlocks on the RS require that to start the bike...with the sidestand down, it must be in neutral. If you place it in gear which the sidestand down, it kills the ignition to prevent riding off and snagging the stand on the road etc..
So if you had the sidestand up before placing it in gear.....since the bike sat for a year...I suspect the plunger for your sidestand switch is stuck partially in (its been pushed in for a year!)
Find the switch down by the sidestand pivot....have someone hold the bike or support it so you can raise the stand, and spray some WD40 on the plunger and work it in and out letting it snap out several times then try it again.

When i put my xj600 into gear it jumps forward and stalls

You probably need to short the two wires together in the side stand switch plug,
It can also be a problem with the clutch switch

Sounds like the clutch is sticking. You may be able to free it off. Bike on centre stand, rear wheel off the ground, run engine, front brake hard on, pull in clutch and put in gear. Apply rear brake. May work,may not. Be careful to keep rear wheel off the ground.

there is a side stand cut out switch to stop you riding off with it down, either the plunger on the switch is stuck in or the switch isnt wired up (or not correctly). hope this helps

Yamaha XJ600 diversion starter motor problem

sound like your starter gear might be missing a tooth or some other king of damage, this shouldnt be a costly repair, but I wouldnt ride too much as it is, if there is a chunk of the starter gear in the transmission, this could cause much damage and be very costly
