Hi, Kennie great talking to you last night this is just for points it's the same stuff that I sent you, and the usual suspects are:
1. Fuel tank empty.
2. The fuel tank has old dead gas.
3. Fuel tank bottom contaminated with ethanol sludge, dirt, water, rust, etc.
4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the enrichner.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
8. Fuel valve/petcock or filter clogged.
9. Fuel line to carburetor or throttle body pinched, kinked or blocked.
10. Carburetor float stuck.
11. Fuel injectors clogged.
12. Fuel injectors stuck open.
13. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a cursory reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.
14. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
15. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
16. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections loose, or connected to the wrong cylinders.
17. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
18. Faulty neutral, clutch lever, or kickstand safety switch.
19. Faulty fuel pump or fuse or relay.
20. A stuck bent or burnt valve.

The original manual states :-
Engine oil for XS1100
not below 5 Celsius (40F) SAE 20W/40 SE
not above 15 Celsius (60F) SAE 10W/30 SE

You will be lucky to find SE spec these days though!!

undo 2 nuts connecting brake caliper to bike (leave the hose connected) once loose and the pads removed, loosen the brake fluid holder lid, the cylinder needs to be pushed back into the caliper, a 'G' clamp is ideal for this.
put new brake pads in as the old ones came out, bolt back on bike checking 1 pad on each side of disk, pump brake a few times untill pressure can be felt on clutch lever, repeat other side. Important..only loosen one at a time replace pads then do other side.

Are u crossing the terminal at the button end or the starter motor terminals? if the termianal u r crossing is at the starte end check the button terminal end and cross them. It could be just abadly corroded button. If not that replace the starter relay, buy a haynes mannual to see where is located, the mannual will be a good investment.
