Triumph Daytona 955i 2004 , Just had a 12,000 mile service but the bike as started to smoke / burn oil this did not happen before the service any idea what the course could be.

If the oil is too thin, that may be a cause or if the oil has cleaned the carbon deposites off the piston rings because it is a detergent oil, that may cause it.
Check the oil that was used and check the crank case breather is not blocked building up pressure in the cranl case with obvious consequences.

2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Fuel tank empty.
10. Fuel tank contaminated with ethanol sludge.
11. Water or dirt in the fuel system, or clogged filter.
12. Restricted, blocked or kinked fuel line.

Battery not charging 03 955i

sounds like the regulator rectifier has gone bad, but the first thing I would do is get my hands on a manual for quick reference d see if its something simple that you could do yourself like replacing the regulator.
